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 Tawna,

    I am facing the similar issue. I have already finished my simulation and my file is tran.tran.trn. Now I am running an ocean script to process the data. Since the data size is very huge some 40 50 GB, I am facing less memory problem.

    I used one method which Mr Andrew Becket has suggested. /forums/p/23266/1313635.aspx

    But I am facing the issue again. Sorry for reposting the issue again, as I think this is the correct thread to solve the issue.

    Best Regards
