Ultrasim DSPF Stitching Failed

Chao Wang

Hi,

Recently, I want to run post-layout simulation using Ultrasim, futher more I want to using xrun+ultrasim to run co-sim.

But from the simulation results, it seems DSPF stitching failed, because the results are the same regardless of whether stitching is enabled or not.

When I check ADE->Simulation->DSPF Log, some errors are as follows:

ERROR  (STITCH-0040)(:38434) : Element I_counter.xi_buf_delay.xi24.xmn0 not found.

I can find  I_counter.xi_buf_delay.xi24.xmn0 instance in spf file and schematic, why the stitching failed?

Is there any other post-layout simulation method using Ultrasim?

Thanks and regards,

Chao

    Hi,

    It seems the simulation is successful even though this error reported.

    But I encoutered another fatel error: "UltraSim is terminating, it received a Segmentation fault signal."

    This error will block the simulation process, so I can't get a result.

    Thanks,

    Chao

    Chao,

    Please contact customer support. Debugging this without seeing the data is going to be rather hard.
