Dear all,

I am using the PDRACULA to do LVS, in the netlist there is description of CAP and RES such as:

Cp n1 n2 1p
xR2 n3 n4 rnwell l=100u w=3u

But there is no CAP and RES check report in the final LVS result. Would you please tell me why.

Thanks in advance
Jay

In your CDL netlist, you need to have (at the top, although not on the first line):

Code:

*.BIPOLAR
*.CAPVAL
*.RESVAL
 

The *.BIPOLAR is needed in order for LOGLVS to realise that it is not a MOS-only design (the use of the word bipolar is a little archaic) - essentially, the idea was that resistors and capacitors would be representing parasitics, perhaps, and so should be filtered out in normal usage for LVS.

Regards,

Andrew.
