Many of you already received communications about the move of the Cadence user community into cadence.com. And many of you have already joined, with over 4000 registrations in the first two weeks.

The new Cadence Community enhances the ability of Cadence users to connect and collaborate. In addition to moving the community into cadence.com -- enabling single sign-on for community, Sourcelink and Cadence events -- the new site is organized around nine technology segments, giving you easy access to product information, training, forums and blogs. Some of the new features include:
  • Ability to respond to posts via e-mail
  • Technology-specific blogs
  • Latest Web 2.0 social networking capabilities
  • Public profile options
  • Private messaging
  • Friends lists
Visit the new Cadence Community today at www.cadence.com/community and join the discussions!

Registration note: Due to the scope of the enhancements and the new SSO registration system, we were not able to migrate existing cdnusers.org member accounts. So new registrations are required, but this enables a broader set of functionality we think you'll enjoy.

Forum note: Under the guidance of forum moderators, we have taken the 20+ cdnusers.org forums and consolidated them into 11 forums on the new site. Posts have been brought over so you can leverage that posting history. CDNusers forums will be set to read only starting 7/30, and cdnusers.org will be redirected to the new community on 8/4.

Best regards,
Mike and Tom

You can Import PADS ASC (ASCII) Files directly into Allegro using File > Import > Pads.. which will build a library on the fly based on the components used in the PADS design. The output is an Allegro .brd file that the libraries can be extracted. I have used the translator many times in the past with good results but the footprints and padstacks always needed to be tweaked on the Allegro side. No translator is perfect but it certainly is much easier than loading Gerber files or spending money on other tools.

I would certainly try and run the PADS ASC file thru the Allegro translator but just one thing to note is that you will have problems translating designs completed on the later releases of PADS, I would still give it a try.

Hope this helps,

HeeHeeHee. Been there, done that dozens of times.

There's a PADS_IN.ini file in the %INSTALL%/tools/pcb/bin folder. You'll probably need to modify it to match the layering in your PADS database. It's not too hard to figure out, and it's nearly impossible to mess up.

You will need to use an older PADS (preferrably v3.5) .asc file to import. I've done it with newer ascii files, but you'll need to change the 1st line to read something like this:

!PADS-POWERPCB-V3.5-BASIC! DESIGN DATABASE ASCII FILE 1.0

Good day.

you can export your libraries by Export>> Libraries option. For exporting your Pads footprint first place your all PADs footprint in one PCB file & then export in ascii format. After that import that ASCII file in Allegro then choose Export>> Libraries option.

Good Luck,

I had the PCB but i didn't have a sch. I've now created a sch and don't know what will happen if i run an update. Will I lose the routing?

thanks Sam

For footprint conversion or exporting your Pads design you don't need schematic.

Thanks
