Modifying an extracted view for post layout simulation.

ghrshomali

I am using IC 5.1.41 and Calibre 2010.4. I have an extracted view which is extracted by Calibre and I want to use it for post-layout simulation. When I modify the extracted view, Analog environment gives the following error:

ERROR: Netlister: the cellview **** was modified since last extraction.

Is there any way to modify an extracted view and use it for post layout simulation?

Thank you very much.

  • wow fantastic trick!

     This saves editing the extracted netlist and doing a command line run simulation. Could this not be incorporated into the Parasitic Aware Design flow? With a health warning I agree. I found it useful as my layout effort is in a different time zone and when I found the extracted view was damaging my performance more than expected  I wanted to alter the design to make it more robust against the layout effects. A quick change to a device parameter within the extracted view then seeing if this has helped the extracted simulation result before issuing the change to layout is so useful
