Convergence Problems with spectre

eppo
eppo over 14 years ago

Hello,

I have a Verilog-A model which works very well in dc analysis, by cons when I try to work with transient analysis I have the  following error message:

ERROR (SPECTRE - 11005) : Matrix is singular (detected at 'net09').

ERROR (SPECTRE - 16080) : No DC solution found (no convergence). 

How can I solve this problem. 

 

Thanks,

    Hi eppo

    First step to solving convergenece issue is to try with the latest version of spectre. If you think that there is no problem with the verilogA model, install and try the latest MMSIM package. : )  If it is possible, it would also be good for you to provide more details about the model.

    Best regards
