eCADSTAR – Schematic Library Searching and Internet Part Resources

January 16, 2020

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 our search. Let’s take a look. As we scroll down the library, you can see we get a preview image of the schematic symbol, the footprint and we can also interrogate the device attributes. If the device has more attributes than we can see in this second window, simply click on the device and we would then be able to scroll down this second window and interrogate all the device attributes. When we dock this window on a second
monitor or make it fill the screen, you can see that the preview images change
to the top and all the devices and the attributes are listed line by line. It’s good practice to assign of part
class to a device, capacitor, resistor for example and then you can isolate your
search per class in the first instance. Okay, Searching for devices. Depending upon how you configure your library, you may have a descriptive part name that includes information like value or package size. Or you may have a library that is linked to an ERP or PLM system and the device
part name is essentially a nonsensical part number. So we need to be able to
expand on our searches. Here I’m simply searching in the part name. I’m entering
22 and the search very quickly isolates all devices with 22 in their part name. Let me change that to 22 u (micro) It returns nothing but, as I mentioned, you 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 classes selection, then you
save that filter with the part class Now imagine for a minute that that
description column we can see next to the values doesn’t have any useful
information in it, we can add an additional level of filtering. 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 that further by manufacturer or
supplier or any other attribute you think might be applicable. 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 the Zukens ECIPS. Our electronic component information partners My default here is to use Samacsys but there are some others You can see my search has returned nothing within my own library, so I can simply click on the globe icon.
It will take the search criteria I have already entered and apply it to the ECIPS search We are presented with a list of devices that contain our keysearch if we follow the link at the end it will take us to availability and cost
from the various suppliers. I can close this window and return to my initial search. The column I’m really interested in is if the device has an eCAD model or not. This one does. It’s also telling me it has a 3D model and the datasheet So let’s go and take a look. At this point you might be prompted to
log into your Samacsys account. It’s a free service, by the way. Just register. Next, it will ask us if we want to open or save. It doesn’t matter which we choose
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 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 an integrated circuit and I will also edit the properties in the
approved status and change them to unapproved, then at various stages of the
design this device will be flagged as unapproved. It’s not prohibitive, it’s just a reminder to go and look at this device and check its integrity Whilst we’re in the library we’ll take a
quick look at how easy it is to create a new device based on an existing device. I’ll take one of these devices at the top and I’ll just simply make a 1210
version. Simply copy the part, then paste, change any attributes you might want to
change and in this instance, I’m going to push into the part and change the
footprint to a larger device. So I’m now editing the part and I’m
telling it I want to assign a new larger footprint. I save the device, save my library and
return to my schematic and we can see the device is available for selection
straight away. 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. It is really easy to
build a comprehensive but importantly manageable library using ECADSTAR.
