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

Does anyone know how to temporarily update the DEVPATH so that a spawned process will recognize the update?

Here's the scenario.

We need to add a directory to the DEVPATH, if it's not already there, so we do the following:

dir = "./devices"
path = axlGetVariable("devpath")
if( ! member( dir parseString(path)) then
axlSetVariable("devpath" strcat(dir " " path))
)

Now this works well, while you are in the Allegro session. Now we want to spawn netin to import a 3rd party netlist and have it recognize that the new directory we added is where to look for the devices.

The code above only affects the current Allegro session and not any spwaned processes, which is the case with netin.

I know that can I manually update the pcbenv/env file to add and then delete the dir from the DEVPATH, but I was looking for a simpler method.

Any suggestions?

I have been trying to find a work-around for this problem for years.

What I did was automatically create a macro to run the netin from within Allegro. (It uses the path already in memory)

Of course the problem with this is having to test/update the macro with every new release.

I have running the netin through a macro (setting the approriate form flags) and it stills doesn't recognize the DEVPATH. Am I missing something? Here is the script I use.

scriptmode +invisible
scriptmode +noinfo
setwindow pcb
netin
setwindow form.niparams
FORM niparams netin_netlist YES
FORM niparams other partslist
FORM niparams filename partslist
FORM niparams syntax_check_only NO
FORM niparams supercede YES
FORM niparams append_device_log NO
FORM niparams remove_etch_other NO
FORM niparams place_never_other YES
FORM niparams import
scriptmode -invisible
scriptmode -noinfo

I was updating the PSMPATH not the DEVPATH. I'll have to do some investigating.

When are you updating the variable?
Our update is done at load (allegro.ilinit).

I am checking/updating the DEVPATH when I run the function. I wouldn't want to put it in the allegro.ilinit as it is specific to the application I am developing.
