*ERROR* (AMS-1245): AMS UNL netlisting" in AMS simulation

RFStuff

Dear All,

I am running a AMS simulation for a testbench. When add a particular cell form a library to it, I see the following error.

*ERROR* (AMS-1245): AMS UNL netlisting 
*ERROR* (AMS-1245): AMS UNL netlisting has failed because of errors in the design.
Right-click the test name on the Outputs assistant pane
and check Output Log->Netlister Log for errors.
Correct your design and netlist again.
*Error* Error during netlisting of design for the point ID (4 1).
("error" 0 t nil ("*Error* "))

When I search, netlister Log file, I don't see any error report.

But, when I removed this particular cell, it works fine.

Could anybody please tell what is the cause for it ? and how to get over this issue.

Kind Regards,

Parents

  • Not really as it's quite hard to diagnose from such little info. If you're using current versions of the tools, I suggest contacting customer support. If not, try updating to a recent version (both of the IC and XCELIUM versions) and see if it's either cured or the netlister log gives more info. You'll need to provide the versions used to support if you contact them...

    Regards,

    Andrew.

    Thanks Andrew for the suggestions.

    But, if I create a new schematic and symbol view (with a different cell name :- original_cell_name_TEST) while copying the exact schematic and symbol contents of the original_cell, the simulation runs fine without any issues.

    Is there something in the original_cell is preventing it running smoothly in AMS ?

    Quite probably, but debugging it without seeing any of the data nor even knowing which versions you're using (still) is not something I can realistically do (yes, quite often I can infer problems on these forums with very little data, but not always). That's why I suggested going to customer support...
