Convergence Problems with spectre

eppo

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,

  • Thank you Quek for your answer. Indeed, in DC simulation I have 3 same warning but it simulates : Line 160 : Warning: dependencies passed throught array arguments ignored. can cause potential convergence problems. I think that is the problem of convergence (warning) that creates a problem in transient simulation. Line 160 ==> I(Vdrain,Vsource)
