Error found by spectre during circuit read-in

[Rajeev]

Hello cadence lovers,

Am trying to simulate an inductor circuit using spectreS and also
spectre. I get this error message while doing so. Any idea why this is
happening.

"
Simulating `raw/inductor' on mercury at 11:08:34 PM, Thur Nov 2, 2006.

Error found by spectre during circuit read-in.
raw/inductor: xl is an instance of an undefined model ind.

spectre terminated prematurely due to fatal error. "

I've included the right model path and that also matched the model name
in the instance properties.
Can anyone with some previous experience with this kind of a problem
help me troubleshoot this.

Thankyou!!

I would regenerate the netlist, look at all the include statement and
cut-and-paste those entries to the unix commandline to see that they
are correct and that the model file actually contains the line
model ind inductor l=...
Then I would consider looking at the spectre -h inductor help since you
obviuously want to use an inductor with a model.

Hi Svenn. Thanks for taking your time to reply. Here's my netlist after
I simulatyed using spectre. I really couldn't understand what to do
next.

Does the path really begin with "#", or is that just you truncating the path.

Also, does the file ind.scs contain a subckt definition for "ind"?

This is bound to be something obvious...

Regards,

Andrew.
