Hi all,
I am trying to create an interconnect capacitance in my circuit.
So I created a schematic view with only the PINs (PLUS and MINUS) and I created the layout of the cell.
My aim is to extract the parasitics for having a schematic to use in simulations.
The problem is that, when I try to run the Calibre PEX (as for the LVS), I get:
"ERROR: Nothing in source.
ERROR: Nothing in layout. "
How can I solve the problem of extracting the parasitics from my cell?
Thanks,
Stefano
Hi Stefano,
I don't have xRC experience but it sounded like "black box" extraction. when I searched for that on Supportnet I found a TechNote that referred to the xRC User Manual section called "Running Gate-Level Extraction".
Do you think that might apply?
I will check.
Thanks.
Hi, Stefano,
I am a student from Tsinghua university,this days i was facing the same problem with you. I found that the calibre pex always reported the error:noting in source,then I checked the calibre input files,and changed it with the .sp file created from the lvs. Finally,it worked. So I guess your problem may be the same. Good luck!
