PSPICE-FOR-TI: PSPICE-FOR-TI - BUG - simulation settings window opens blank

Hi Robert,

Does this happen on every project? If so, please exist PSpice for TI, rename these folders and launch it again:

"C:\cds_spb_home\cdssetup\ORCAD_CAPTURETIPSpice_Install"

"C:\cds_spb_home\cdssetup\OrCAD_PSpiceTIPSpice_Install"

If this happens on a few projects only, then please share the projects.

Thanks,
JC

Hi JC, thanks for fast response.

Unfortunately that renaming hasn't solved the problem - empty simulation settings window persist in both old and very new project. Also - the two folders were recreated as soon as PSPICE has restarted - that is, I suppose, expected.

Actually the problem happens on any project, even trivial one created from the scratch.

Any other suggestions ?

Thanks

Robert

Hi JC,

I did requested searches and found that indeed PSPICE.ini variable "CDSROOT" is not listed under user environmental vars.

PSPICE.ini:

LIBPATH=$CDSROOT\tools\PSpice\Library;C:\cds_spb_home\cdssetup\pspTILibDir
BACKUP=$CDSROOT\tools\pspice\Backup

I have tried to fix it adding this variable manually:

so now all the paths aims to existing directories (hopefully to the right ones ?).

dir %CDSROOT%\tools\PSpice\Library;C:\cds_spb_home\cdssetup\pspTILibDir

 Directory of C:\Cadence\PSpiceTI\tools\PSpice\Library

But unfortunately this hasn't made the PSPICE working, the settings window is still empty, simulation can't be started.

Any other advice ?

Hi Robert,

If you don't have other tools from Cadence installed, then it is normal that there's no $CDSROOT. That being said, what's your time zone and what time during the day would be a good time for a conference call?

Thanks,
JC

Hi, see my PM

Hi Robert,

BTW, what's your OS?

Would you please try this as well?

Edit this file: "C:\Cadence\PSpiceTI\tools\bin\orCefSettings.ini", append the following line to it:

lang=en-US

Open PSpice and type below command in command window and press Enter. Wait for sometime and once the command is executed successfully, restart the tool and see if that helps

DboTclHelper_ReRegisterOrCADPlugins

Thanks,
JC

Hi JC,

OS: Windows 10 Pro (stated in my initial post)

The ini file you mentioned already has lang=en-US.

On the other hand the COrTclUtils_sGetLocale command gets "en-GB" - not sure it makes any sense.

Well, I have executed the command you asked anyway.

It has not fixed the problem.

Please take in to account that our PSpice installation has been already working well for some time - ca 2months ago. The point is that it has stopped working recently. I would suspect some update on the background.

Thanks and Regards

Robert

Hi Robert,

so have you tried to replace "lang=en-US" with "lang=en-GB" in "orCefSettings.ini"?

Thanks,
JC

Yep, no change, sorry, PSpice still doesn't work.

Hi JC,

we have run out of time already. Reinstalled everything and have PSpice actually working. We did no updates, no new libraries etc. hopefully to keep PSpice alive for our actual project.

Thanks for your effort, although the problem was not resolved. I may reopen it when we encounter the bug again.

Thanks & Regards

Robert
