Title: errors caused by netlist extracting
Post by Robert on Nov 11^th, 2007, 10:10pm

hi, guys
I use the cadence IC5141 ADE to run analog simulation, but i can not run it successfully, since there is always a error "input.scs: R62 is an instance of an undifined model subcircuit". i check out the netlist created automatically by ADE, it is illustrated as following:

R62(net100 net99 0) subcircuit length=15u width=2u

but the right one should be:

R62(net100 net99 0) nplus_u length=15u width=2u

what happen? and how can i fix this problem, hope someone give me helps, i would really appreciate it, thanks!

The netlist is created by what the netlister get's from the
component description format (CDF).
And there might the problem be located.
I assume that you have no proper description for your resistor.
Check you CDF with 'CIW -> Tools -> CDF -> Edit...'.

CDF Type should be base, then check the for the correct
model name under 'component parameters' and your
check your simulator information for the desired netlister
as well.

hi,bernd
thanks for your kindly reply.
i have fixed the problem, i did not set something correctly in the bash file, i replace the "export CDS_Netlisting_Mode="Digital"" by "Analog", now the simulation can be run successfully.

Sounds reasonable with CDS_Netlisting_Mode="Digital" the netlister does not
look for the CDF information as well.
