"spectre + aps" issue : FATAL (SPECTRE-208) ?

samung

Hello,

using spectre MMSIM10_11 with the option : +aps

I have the following error message in the log file :

Fatal error found by spectre.

    FATAL (SPECTRE-208): You do not have permission to run Virtuoso(R) Spectre.

The point is the following :

I have let's say, a deck of 20 simu to launch (it means 20 times the cmdline : qs spectre +aps +mt=2 (or something) path.../input.ckt). There is a license servor query before each round of simu launch returning the available nb of licenses (&tokens) to use. The behaviour, is weird, 1st round simulations don't have any issue (like the above one), however, the 2nd round simu have all the issue. And there is obviously the license servor query before the 2nd simu launch.

Does it mean, that I have to include a tempo after the "lmstat" cmdline creates the file with all the tools licenses available & used at a "t" time ? File from which I extract the available nb of spectre licenses to use ?

Actually, using ultrasim for the same stuff, I do not have any issue like this one.

Thanks !

  • It's pretty hard to tell what your problem is other than the fact that at the time the simulation launches, it can't get a license, but you might want to add "+lqt 0" (which means to wait for a license forever before starting), or maybe "+lqt 900" to wait up to 900 seconds - depends if you really want it to potentially queue for ever. If using tokens, you might also want to add +lqmmtoken as this does true license queueing on the tokens, rather than repeated polling.

    Maybe your estimate of licenses available is incorrect, or maybe the timing is such that between the check and the simulation actually starting, the conditions have changed? If so, one of the license queuing optons might just be a safer way to handle that.

    Regards,

    Andrew.
