Unable to allocate memory

nmobini

I use IC-5141 sub-version 5.10.41.500.6.139.

I am doing transient analysis of a large analog circuit. The simulator I use is Virtuoso ADE 7.1.1.071

As soon as simulation is done and waveform are to be plotted. I get these errors. 

ERROR: Unable to allocate memory for locator map bnode split.

ERROR: Unable to allocate memory for transition file rw buffer.

How can I fix it?

    Hi nmobini

    Would it help if you plot on a machine with more memory or plot less signals? By the way, ADE (Analog Design Environment) is the simulator interface which you use to run the simulator. I think the simulator which you are using is "spectre".

    Hi, Quek:

    I am facing similar questions but not exactly the same. After finishing my 3-day long simulation with selected saved option, the following error appears. I can actually plot the curve but since I simulate 256 data points, I would like to show the 256 data points on plot. The curve only display around 30 data points. The total file size is 1GB only.

    ERROR: Unable to allocate memory for variable transitions block (tran).

    I use IC6.1.5.500, can you give me some suggestions how to work around it?

    Thanks

    Hi Gaofeng

    It is not a good idea to append to an old thread which has already ended in Apr 2010. This is against the forum guidelines. In future, please kindly start a new thread for your issue. This will also help us to concentrate on only your issue and not be confused by the old issue.  :)

    Would you please try the following?
    terminal>setenv CDS_AUTO_64BIT ALL
    terminal>virtuoso &

    The issue seems to be due to insufficient memory. If the machine has more than 4Gb of memory, using 64bits Virtuoso will most probably help to resolve this.

    BTW, I tried the command you suggested in ~/.cshrc and source it after that. It works. I get 257 data points all.

    Hi Gaofeng

    Thanks for the update. It is good to know that using 64bits Virtuoso has helped to resolve the issue.
