1. Get the data sheet. 2. Identify the package. 3. Take note of center to center pitch of the pins. 3. Search your library for a corresponding footprint. 4. If...
Colleagues, To make a split ground plane in a 4-layer board I need to switch the ground plane layer from "Plane layer" to "Routing layer". Do I need to change...
Nick, I highly recommend getting this book called, "Complete PCB Design Using Orcad Capture and Layout". It really explains how to do Split Plane. For a simple...
Hello there!! I would like to know if someone has the following footprints : TQFP-64 20-pin TSSOP PQFP-208 or where can I find these footprints ? thanks Manu ...
Manu, TQFP-64 and PQFP-208 are in a library QUAD.olb TSSOP-20 is in SOG.olb Both QUAD.olb and SOG.olb are standard libraries that come with OrCAD installation....
Hi all! Can anyone tell me if there is a footprint in the library for the Camden connector type CTB93HE series. the one I`m actually using is the /12 varient...
Folks, I've finished a layout in OrCAD 9.2 Layout Plus, and I want to run DRC on it. It's a simple board with only 45 nets, but I'm getting few hundred DRC...
Colleagues, AFAIK, OrCAD doesn't come with a layout footprint library for commonly used switches and buttons. There aren't very many switches and buttons in...
Hi! This is my first post. I have a.... bad english and you will need a little practice to understand to me :| It wanted to raise in this post to unify the way...
???dellectronics, Check out this link. http://www.pcblibraries.com/resources/libraries/OrCAD.asp?a=vw They also have a free footprint calculator. Also, you...
... Nick, Can't you copy the part and paste it as a new part in the lib? I've seen this also, the "Pins Visible" property is disabled - I usually see this when...
Man - the layout I'm working on has far too many Vias - boy do I miss the good old days when through-hole was the mainstream! I'm an electronics hobbyist, not...
Hazelnut, These are controlled in the SPECCTRA (not shouting here, just making it so someone can search for this topic later) router. I have never run the...
Terrence - Thanks for the reply and even more for the tips! I admit I've been using SPECCTRA (I'm not shouting here either ;)) without any kind of rules...
Thought I'd give you a little hint here. If you're trying to impliment something like a '245 you're barking up the wrong tree. I have been doing xilinx on and...
Hi PM - Thanks for the tip! So I guess I wasn't going crazy trying to implement 245 type transceivers into a CPLD - it can't be done! You hit the nail on the...
yup, I use Orcad capture to design for Xilinx PLDs too. If anyone wanted them I could post my libraries - I had to do quite a bit of work to sort them out so...
