memory error

Andy Liu
Recently my design goes into the last stage. The simulation was very slow (lasting several days). Moreover, my simulation software crashed several times. I got the error messages below.

(1). Unable to allocate memory for transition file slice variable transition index level (read). ERROR: Unable to allocate memory for reading transition file unpack map. Insufficient memory to continue. Cannot satisfy request for 364 more bytes of memory. Terminating process. malloc: Cannot allocate memory.

(2) Unable to allocate memory for transition file slice variable transition index level (read). ERROR: Unable to allocate memory for transition file slice variable transition index level (read).

My hardware is an eight-core Intel CPU with 32 GB memory (The memory size is already the largest supported by the hardware). I use Spectre in analog design environment of cadence.

My questions are:
(1) Is my memory not large enough?
(2) Is there any way (e.g. environment setting) to bypass these problem?

  • Hi Andy, How did you solve your problem? I met the same problem as you did when I was doing Monte Carlo analysis of my layout. Some files in my PSF directory are really large, more than 20G in size. Hope you can do me a favor, I really appreciate it.

     

    Best regard,
