Title: ncsim error during circuit read-in - AMS running from HED
Post by raftman on Feb 16^th, 2009, 5:00pm

My design is elaborating ok, but after ncsim launches the simulation never begins and the following error is in my ncsim.log

Error found by spectre during circuit read-in.
test_TOP.IADC.IO.I33.IPULL: error in evaluating parameter 1.

spectre terminated prematurely due to fatal error.

I've looked through the verilog.ams netlists for cell I33 (which instantiates IPULL) and IPULL and not seeing anything with a parameter named, or set to, 1. I also looked at the properties in the schematic and haven't found anything.

anyone know where I might look for more information about what's causing spectre to stop?

Can you post the instance line for IPULL from the netlist?

This may be a CDF parseAsNumber issue - see sourcelink solution 11086400.

Regards,

Andrew.

sure, of course, following is the instantiation line. I will check the sourcelink solution you mentioned.

Thanks!
Andres

What about the module definition for IPULL? (the instance line didn't reveal much, other than that there were no parameters).

Regards,

Andrew.
