LTspice

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 analogue 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 analogue circuit’s performance out of specification, without the number of simulations getting unrealistically high.

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.

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.
