eCADSTAR - Schematic Library Searching and Internet Part Resources

Video Transcript

For eCADSTAR Zuken have moved to a database format Library. This gives the user faster response times when searching and then expanding levels of filtering within that search.

Let’s take a look.

I’m just enabling the Library viewer window and it appears in my preferred location, docked to the side. Like all the panels in eCADSTAR we can dock these anywhere we like and we can also drag them off onto a second monitor. 

As we scroll down the library you can see we get a preview image of the schematic symbol, the footprint and we can interrogate the device attributes further. If the device has more attributes than we can see in this window, simply click on the device and we would then be able to scroll down in the attribute window as well.

Let's replicate this being placed on a second monitor and maximise it.


If we were to dock this window on a second monitor the preview images change the location and we see all the attributes displayed.

So searching for devices, Depending on how you configure your library you may have a descriptive Part name that includes information like Value and package size. Or you may have a library that is linked to an ERP / PLM system and the Part Name is essentially a nonsensical Part Number so we need to be able to expand on our search.

You can see here I am on the PARTS search. And I’m searching on Part Name. Its good practice to assign a Part Class to a device, Capacitor, Resistor, for example, to be able to isolate your searches further, but it's not necessary.


Here I’m simply searching in the Part Name.  I’m entering 22. The search very quickly isolates all devices with 22 in their part name. Let me change that to 22u.  It returns nothing.  but as I mentioned we might have a Part Number based library so let’s expand this filtering and add a value category.

These filters can be saved per part Class as well so if there is a common attribute that determines a specific part class’ selection then save the filter with the Part Class.

Now with the additional filtering in place I can repeat that search in the value field. As expected the same device are returned as they must all also have 22 in the value attribute. Let me change it again to 22u. Now it's just showing me the 22u devices.

Imagine for a minute that that description column we can see doesn’t have any useful information in it. We can add another filter level. 


Here I’m going to enter package type and see if we have an 0603.  Success.  Depending on your library evolution you could then isolate further by manufacturer or supplier. If I perform a search in my library and it doesn't return a relevant device I have the option to search in one of Zuken’s ECIPS.   Electronic Component Information Partners. My default here is to use Samacys but there are others.


I simply click on the globe, it will take the search criteria I have already entered and searched the ECIP. You can see we get a list of devices that might match our search criteria. My search was pretty loose, ST32. 


Let me pick one and we’ll follow this link where it will give me availability and cost from various suppliers. I can close this window and return to my initial search. The column I am interested in is if the device has an ECADS model or not. This one does, and a3D model so we’ll select this. At this point you may be prompted to login to your Samacsys account. This is a free service by the way.


Next, it asks us if we want to open or save. It doesn’t matter which we chose here. I have the tool configured to automatically load the device onto my cursor so I can place it immediately in my design. At the same time, it is building the device into our MASTER library even though the library is not open.


Let's open up the library and take a look.  Here it is. I’m going to assign it a Part Class of Integrated Circuit and I will edit the properties in the approved status to unapproved. Then at various stage of design this device will be flagged as unapproved. It's not prohibitive. It's just a reminder.


Whilst we are in the library, lets see how we can quickly copy a device to a new device. I’ll take one of these devices at the top and I’ll make a 1210 version. Copy the Part, Paste it onto a new line. Change any attributes if necessary. For this one, I’m going to change the footprint. We close the library and return to the schematic you can see the device is now available.


We’ll be taking a closer look at the library in another video but as you can see eCADSTAR offers us fast, intuitive search facilities. We’ve also had a brief insight into sourcing parts via the internet using our ECIP and you’ve seen how easy it is to copy an existing device. Its really easy to build a comprehensive, but importantly manageable library using eCADSTAR.
