spectre - 7031 error: SST2: Input/output error

pratikdd

 Hi,
I am doing a transient analysis for around 100us to check for a PLL Design and after 640ns im getting an error message:
Error found by spectre at time = 639.8ns during transient analysis 'tran'
ERROR (SPECTRE-7031) : SST@ Error: Input/output error.

Can someone please help me put regarding the same.
thanks in advance.

  • It might be that the disk filled up, or it might be a bug in the SST2 output from the simulator. Assuming you're using a recent MMSIM version, I'd suggest reporting it to customer support at http://support.cadence.com but you can probably  workaround it by setting the output format to psfbin or psfxl on Save->Options (near the bottom of the form). If that's not there, use:

    envSetVal("spectre.outputs" "simOutputFormat" 'string "psfbin")

    In the CIW before starting ADE (can go in the .cdsinit too)

    Regards,

    Andrew.

  •  Hi Andrew,

    Thank you so much for the instant reply. Yes, indeed it was due to disk space. I deleted all the .psf files which gave me lots of free space. thanks for your reply
