Hi friends,

I tried to run AMS designer tutorial but I have trouble. In the log file we see:

Fatal error found by spectre.
You do not have permission to run Virtuoso(R) Spectre.

However, my license is OK. I can run spectre alone. In cadence website, people say:

Problem

You have plenty of MMSIM tokens and are running a mixed signal design simulation via AMS-Designer. You run the simulation with Spectre as the analog solver and in doing so you see the above error message.



How can this be? There are plenty of MMSIM tokens but none seem to be getting used?
Solution

CCR 591581 has been filed for this issue.  This issue is caused by having the -profThread option in ncsim.  This option gets added to ncsim when you select "Allow profiling of threaded processes" in ADE.

Until the CCR is fixed, you need to turn off/remove this option in order for ncsim to run.  This CCR is currently planned to be fixed in the IUS 9.2 s16 release.

I have followed but it doesn't help.

Highly appreciate your help.

Rommel.

Hi BOE,

Thank you for your reply. We have only one license server for cadence, so I do not think we need to choose the license. Do you have any other suggestions.

Hi BOE, and friends,

Actually it is the bug of IUS. I have just updated IUS from 8.2 to 9.2 and now the AMS is OK. I highly appreciate your help BOE.

Anyway, I want to export one design macro from Cadence Virtuoso to Synopsys IC compiler. For physical part, I can export to a gds file, and import it from ICC. For logic part, I still do not know how to do. There is a program Liberty but it is for standard cell. My macro is large (more than a DAC). I only need a dummy db file for logic part. Could you tell me how I can do.

Thank you so much.

Rommel
