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.
You can use:
and then save it. Note that this should obviously be done with caution because you may be destroying the integrity of the connectivity when you are editing the extracted view.
Thank you very much Andrew.
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
The idea is that you ought to be able to use the parameterisation flow to (e.g. the Variables and Parameters) assistant to do these "what if" experiments, but currently it's not possible with extracted views. But it's being looked into...
what's the equivalent command in ic6?
