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

vinod joshi

I got this message in the log file while performing the DC simulation. Please help

error found by spectre during DC analysis `dcOp'.

ERROR (SPECTRE-16385): There were 8 attempts to find the DC solution. In some of those attempts, a signal exceeded the blowup limit of its quantity. The last signal that failed is I(I7.I4:Ttrans_flow) = -1.80144 GA, for which the quantity is `I' and the blowup limit is (1 GA). It is possible that the circuit has no DC solution. If you really want signals this large, set the `blowup' parameter of this quantity to a larger value.

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

    Well, if you want us to help then you better tell us a little bit about your circuit, share a netlist, screenoshots ....etc. This error message can come a simple RC filter as well as from a more complicated PLL. Ideally:

    - Post a netlist

    - Post a logfile (it has Spectre versions) . ...etc

    - Make sure you don't post anything sensitive and/or under NDA.
