Get Results With Schematic Editor— Consistent, Connected, Comprehensive

Schematic Editor is eCADSTAR’s design capture application—a key part of our unified, internet-connected EDA solution for PCB design. eCADSTAR applications are clear and consistent. You work quickly and correctly. One user interface style. Universal web connectivity. Industry-proven technology. A short learning curve, but all the detailed features you need to optimize your designs.

Instant Web Part Access

Save time when you prototype, even before the new components you’re using are in your master library. Download what you need and carry on working.  Find a web part, place it and it becomes part of your schematic. Forward-annotate to PCB Editor. No need for a final form factor yet. Create a prototype in seconds—check it out in 2D and 3D physical context right away.

Web part lookup is part of eCADSTAR’s connected design platform, with access to extensive online parts libraries, including 3D models—and downloaded parts are fully editable.

Block Hierarchy

Schematic blocks make your design easier to understand. They are great for design reviews and they equip you for maximum re-use, design integrity and teamwork. It’s easy to share blocks with other engineers, so you can refine, optimize, and keep similar circuits consistent.

Schematic blocks are parts of a schematic design that you identify and save as re-usable work during schematic capture. This means you can share them with other engineers. Blocks add hierarchy. A hierarchical PCB design adds structure, making electronic designs easier to interpret in reviews. It empowers concurrent design and simultaneous working on parts of a PCB design or system.

Design Variation

Structure design variation from schematic entry through to physical design. Decide which components are fitted and even which parts are used in each variant. A way to think of variation is that the conductor metal on the PCB is always the same, but you can vary what is assembled on it.

Design variation is how you manage different varieties of the same bare-board PCB without duplicating the parts that do not change. For example, premium versions of a PCB could include additional HDMI or USB ports or more memory.

Signal Integrity

Good signal integrity is essential for many PCBs, even if the products they go into are not high-speed. Many standard parts, including memory and I/O, run at high speeds. This means they use up less PCB real estate, because signals that run faster can travel over fewer tracks. eCADSTAR supports professional signal integrity control in both schematic entry and physical PCB design, using consistent methods throughout. In Schematic Editor, you can use simulation and analysis to see how your proposed layer stacks, track widths, spacings, etc. will perform when they are laid out on a PCB. Even better, when you’ve decided what you want, you can instantly create a PCB prototype and lay out as much or as little as you like. Then you can drill down to fine detail, using the same simulation and analysis you used in Schematic Editor.

Control high-speed layout without external software in a consistent, unified environment. Check the high-speed performance of proposed topologies, layer stacks, track widths, track spacings and PCB materials before you commit to physical design. PCB signal integrity tools used to be bolt-on, with a variety user interfaces. With eCADSTAR, what you need to achieve good signal integrity is built-in.

Collaboration

eCADSTAR is a next-generation solution, not a collection of disparate EDA applications strung together to address new issues as they emerged. Want to copy a circuit or a block from one schematic to another? Just open both then select, copy, paste. Want to share a high-speed scenario and its simulation results with another engineer? Just save and send. That engineer can open them and even edit them, sharing their suggestions back to you in the same way.

Multi-Instanced Hierarchy

Structure your schematics to maximise re-use opportunities and minimise copy/paste errors with multi-instanced hierarchy. It provides block structure with clear functional overviews and declutters reviews of circuits containing multiple channels (like Audio circuits).

Furthermore, define one block and create as many instances as you need in addition to avoiding copy/paste in channeled or repeated sections of circuitry, such as multiple USB I/O circuits. Plus upgrade key schematic circuits quickly and safely by instantly propagating block enhancements to their instances.

SPICE Controller

SPICE Controller is best paired with LTspice^®, which is free to download and use. Simulate analog circuits while keeping key simulation setup with your schematic design. That makes analog circuits much easier to manage, review and re-use, even for single-board multi-technology PCBs.

Successful analog simulation requires precise setup. Benefit from the industry-proven analogue simulation facilities of LTspice^® with simulation data that is much easier to set up and manage.

Local Parts, Web Parts, PCB Technology and Design Rules

Library Editor is eCADSTAR’s library management application—a key part of our unified, internet-connected EDA solution for PCB design. Fast, consistent, and connected. Easy to learn, but with the power you need to create and maintain consistent core library data.

Library Editor provides everything you need for library management in one place.  Naturally, it complies with the same user interface style as other eCADSTAR core applications. All this means there’s a single short learning curve that gets engineers up to speed super-fast.

Library Editor combines all library editing and management in a single application—parts, schematic symbols, PCB footprints, pads, 3D models, web parts download and merge, PCB technologies, and design rules.

PCB Technology & Design Rules

PCB technology and design rules are part of your master library. You manage them in Library Editor, just as you do with other library data, so there is just one short learning curve.

PCB technology and design rules are structured for maximum re-use. That does more than save valuable time—re-entered data is error-prone data.

With eCADSTAR, once data is entered and verified, it becomes premium IP that you can build on with confidence.

A layer stack need not be identical to re-use a PCB technology. If the top and bottom PCB layers, or a pair of inner layers are the same, then it’s much safer and more efficient to reference just one master definition. If a set of spacing or track width rules are the same on completely different layers, then the same applies—define once and then reference as many times as you like.

A layer stack need not be identical to re-use a PCB technology. If the top and bottom PCB layers, or a pair of inner layers are the same, then it’s much safer and more efficient to reference just one master definition. If a set of spacing or track width rules are the same on completely different layers, then the same applies—define once and then reference as many times as you like.

This philosophy carries over into the PCB design itself. If your PCB layout has a different number of layers from your reference layer stack, you can just pick the ones you want to create your production stack.

And if you need to, you can customize PCB technology and rules locally, in your design itself.

PCB technologies define materials, layer thicknesses, layer types, and layer stacks that you use to create PCBs. Design rules are settings like track widths, via spans, differential pair spacings, and clearances that you apply during PCB routing and placement. Technologies and design rules are structured for maximum re-use, including design rule stacks that you can compose from known-good lower-level rules.

Schematic Symbols, Parts, Footprints, Padstacks, Pads & 3D Models

With Library Editor, you manage all the key items you put on your schematics and PCBs in one place—even if you merge online parts into your library. A straightforward, consistent user interface. A true Windows GUI, so easy to use side-by-side with other applications. For example, adding data from one library to another is a straightforward copy and paste.

Schematic symbols often represent parts or functions within them, but they can also be items like sheet connectors, power supply voltages, and routing star points. 

Footprints are what gets imprinted on the unpopulated PCB for a component. Pads, conductor shapes, solder mask, and any other data layers. You can include documentation layers too. Footprints can consist of 3D models. You can import STEP format models and these are often included in data for web parts. 

Parts unite schematic symbols and footprints, managing pin assignments and settings like legal pin swaps and the symbols used to represent each function (called “gates”, but can be items such as IO banks or multi-voltage power supply symbols). 

Just as with PCB technology and design rules, these items are structured for maximum re-use and minimum repetition. You can independently create and edit pads, padstacks, footprints, the parts that use them and the symbols that represent those parts—but without switching applications. 

You can download web parts and merge them directly into your library.

Once in the library they become fully editable and you can adjust them to, for example, comply with your company standards. eCADSTAR features direct integration to some of the world’s largest part vendors and online component libraries, including Allied Electronic & Automation, Arrow, Digi-Key, Mouser Electronics, RS, SamacSys and Ultra Librarian.

You can open schematic symbols, parts and footprints for editing from Library Editor’s main tab. When you edit footprints, you can even split to multiple views in any mix of 2D and 3D, to avoid later surprises due to out-of-view errors. Built-in access to cloud component libraries, including electrical schematic symbols, datasheets and 3D models makes PCB prototyping fast and accurate and you can manage part obsolescence and sourcing dynamically. With eCADSTAR’s fully-structured PCB parts libraries, you only enter data once and re-use it anywhere, bringing greater efficiency, accuracy and reliability.

3D Model Manager

The 3D Model Manager organises your 3D models to suit your standards with fantastic 3D visibility. Rename, assign or delete 3D component models and have transparency on what each 3D model represents in your library. For example, matching a corporate footprint naming convention

Even organise these models into subfolders bringing structure and clarity to 3D component models, such as organising them according to package style.  You can visualize these models in 3D as you manage them.

Additionally import models from a wide range of popular 3D formats, expanding your choice of 3D model sources.

CONSTRAINT BROWSER

Setting constraints means you can verify that your design meets standards—internal or external. And your design follows those constraints as you go, because it costs much less to avoid an issue than to find and fix it later.
A constraint set early works for you, but consistency is critical. A constraint in library design rules must look the same and work the same as one applied locally, in schematic or PCB.

Necking-down DDR4 strobe routing by switching between differential pair rule stacks as it approaches its controller. Differential pair rule stacks defined in the library can been set as constraints using the unified Constraint Browser in both schematic and physical PCB design.Xi

Design Rule and Constraints

Set or edit constraints in Schematic Editor or PCB Editor. Define technology and design rules in Library Editor. Keep your design settings in sync with your master library or make them local.

Local settings can be useful for prototyping, while synchronized settings are best for production.

Manage constraints in Constraint Browser, in a clearly presented object hierarchy. Look and feel is the same whether you do that in Schematic Editor or PCB Editor.

Forward and back annotation ensure that your constraints are always in sync. Define classes and groups to organize your design and constraints. Create differential pairs and buses. Cross probe selections between the canvas and Constraint Browser in both Schematic Editor and PCB Editor. Highlight objects you constrain by setting colors and taking advantage of visibility options such as shading between differential +/- and E-net pin pairs.
Route with confidence, assisted by simultaneous display of real-time measurements versus constraints.

-Verify constraint compliance with built-in, consistent simulation

Verify signal and power integrity with time and frequency domain simulation

Drive and organize your analog simulation more effectively

In our increasingly digitized world, analog circuits show no sign of diminishing. Mixed analog/digital designs are very common. Sensors, controllers and multimedia interfaces all include analog circuits.

Traditionally, analog analysis has been separate and tackled by specialists. There’s no substitute for expertise but keeping data in a different place is never a good idea—especially when there are engineering changes or enhancements.

With Schematic Editor SPICE Controller, you can set up simulation directly and that setup stays with your schematic design.

Once you are simulating with LTspice™, there is no substitute for experience and its extensive, freely available online information. But keeping the setup with your design data and closely linked to it makes tasks like AC analysis and corner case checking parts of a joined-up process.

Best-in-class analog simulation for your PCB designs

Schematic Editor SPICE Controller provides enriched integration, as well as ideal facilities to explore design options while keeping your setup with your schematic.

-Use the leading, proven analog simulator LTspice™ while keeping key data with your eCADSTAR schematic

-The LTspice™ SPICE circuit simulation software is free to download and use

-Explore operating ranges and passive component values dynamically, even if you have not yet assigned production parts. Decide on the tolerances, wattages, etc. that you need to make your design both economical and robust

-Perform Monte Carlo analysis to check for random combined-effect issues that can put your analog circuit’s performance out of specification, without the number of simulations getting unrealistically high.

Preserve and recall settings easily with built-in simulation control

You can simulate parts of your schematic or your whole design. It is usually more useful to focus on specific circuits. LTspice™ models have their own pin numbering conventions. As well as mapping to the correct pins to simulate components like transistors, diodes and operational amplifiers, you can override the values of passive components like resistors and capacitors. You can, for example, explore the effect of different bias levels, passive filtering or alternate independent voltage sources.

You define the simulation setup and LTspice^® model pin assignments directly in Schematic Editor. This means the setup data stays safely with the design instead of being separate.

Simulate your analog circuits with powerful, industry-proven methods

Once you have set up the simulation parameters, you can save and re-use them for the same schematic. The simulation parameters are paired with the simulation netlist you generate, so they are valid only for that circuit. Once LTspice^® simulation is running, you have all the facilities that it offers.

This simulation netlist is for one sheet of the schematic: an audio amplifier circuit. You can also simulate framed areas of your schematic or your whole schematic.

In this simulation of an audio amplifier, the lower, red traces show the amplitude of the input signal being swept in 0.1 Volt steps. The corresponding blue traces above show the response at the speaker output. You can see at what input level the output stops clipping. In audio terms, this would be the point at which a guitarist stops sounding as though they are using a fuzz box.

Roll the dice before production and beat the odds of a surprise

As its name suggests, Monte Carlo analysis is about rolling the dice. What will happen if multiple things over which we have no control vary at random and simultaneously? What if the environment is particularly hot or particularly cold and at the same time, one or more of the components is operating at the limits of its specification?

Simulating all situations where there are multiple variables means a very large number of simulations. If you roll two dice at Monte Carlo, they can land in 6×6=36 different ways. If you have, say, five variables, each in ten different states, then your number of simulations would be 10×10×10×10×10=100,000.

The beauty of Monte Carlo analysis is that instead of simulating all values, it intelligently randomizes which values to consider based on mathematical statistics.

Here is a simple example: checking the effect of a ten percent versus a one percent tolerance for the input and output resistors of an operational amplifier. You choose the number of samples and variations in the two values are distributed intelligently to show the variation in output without having to simulate every case.

The two resistor tolerances are set by these parameters. For the first Monte Carlo simulation, they are set to 0.1, which represents a 10% tolerance.

There is about a 1V drift in output amplitude as both resistors drift from their ideal values—too much for this circuit. The setup created within SPICE Controller in Schematic Editor is shown in LTspice^® form in the same view.

There is about a 1V drift in output amplitude as both resistors drift from their ideal values—too much for this circuit. The setup created within SPICE Controller in Schematic Editor is shown in LTspice^® form in the same view.

When both resistor tolerances are set to one percent, the same Monte Carlo simulation shows a very small output amplitude drift, so one percent tolerance resistors are chosen for this circuit.

What Schematic Editor’s SPICE Controller gives you and how best to use it

Why not just use LTspice® directly? You can add and connect components right there and simulate them. There is no reason why you should not do that too, but SPICE Controller keeps the simulation setup with your schematic design and links simulation to your schematic design data. That makes LTspice® simulation cases both easier to manage and easier to set up. It closes the loop between your schematic design and your LTspice®analysis in a way that means you can retrieve it later.

The recommended way, preferred by many analog engineers, is to create separate mini designs in Schematic Editor that they can use as design building blocks, together with their simulation setups. These can be imported into different schematic designs while keeping the reference copies of the analog designs separate. If an analog designer enhances one of these circuits, it will be available as an upgrade to designs that use it at a time of your choosing.

Here is a demonstration that goes deeper into LTspice^® simulation from Schematic Editor
