Insufficient memory to continue{MMSIM12}.

RFStuff

Dear All,

I was running a pexed circuit with APS enabled ( Manual, Cores-4). CPU has 4 cores.

In spectre.out, I saw the simulation (both DC & Transient) ended with ZERO errors proerley.

But, icfb(IC5141) inadvertently ended with following MESSAGE in the termial

 Insufficient memory to continue.
Cannot satisfy request for 87 more bytes of memory.
Terminating process.

Could anybody please tell why this is happening and how to fix this.

Kind Regards,

  • Maybe Virtuoso (icfb) is running out of memory due to the memory consumption of having the database in memory, memory used during netlisting, memory consumed during loading and plotting of the simulation results.

    Unfortunately in IC5141 you only have 32-bit versions of icfb and other executables that contain ADE functionality. So you are limited to less thatn 4Gbytes of virtual memory, even if you rmachine has more memory. This is solved from IC614 onwards, where all of Virtuoso is available in 64-bit mode and can therefore access more memory.

    Hard to know precisely where it's running out of memory. The ideal solution would be to migrate to a newer version which doesn't have this limitation, but since that would involve a database migration, that may not be so straightforward.

    If it's just about plotting waveforms, you could always run "viva" standalone from IC616 in 64-bit mode ("viva -64") and open the results database with the results browser and plot it that way.
