CDL Import

[Szekit]

Hi,

Somebody has done this for me in the past but I didn't pay attention
on how to do it. Now it's my turn to do it and I am seeking your
help!!!

I have a CDL netlist of various standard cells and I need to import it
for schematic capture and simulation. What is the solution??

Thank you very much for your assistance!!!!

Hi,

I am able to import the CDL netlist into schematics!!

However, the AS, AD, PS, PD don't get updated!! What can I do? Do I
need to write my own SKILL? Any easier solution????????????

Let me elaborate more...

The AS, AD, PS, PD parameters only get updated when I go into each
schematic and modify the w parameter. In another words, when I CDL in
a netlist, AS, AD, PS, and PD are assigned with default parameters. I
need to modifty the w parameter in order to trigger the CallBack
function to update the AS, AD, PS, PD parameters. Any ways to do this
in an automate steps?

Thanks for your comment.

I was able to update those parameters at the end with a script I got from my friend.

Not sure what you want here.

When you rad in a CDL netlist, do you have the AS AP PS PD info?
(i.e. is the source a layout? )
the proper way is to have the fields populted on Reading them in.

Note that these parameters are highly dependant on layout topology.

I have created a set of callbacks that CAN recalculate the areas &
perimeters of the sources and drains
based on a parameter (called style , i think )
The style would have choices like: Nominal, Minimum, Custom.

When a mosfet was placed in a schematic, the default would be Nominal and
the S/D sizing numbers would be
calculated assuming an isolated mosfet, rectangular layout and minimum
design rules. When a schematic was
backanotated form an extracted rep, we would set the default to custum and
read i the measured S/D sizing numbers
from the extracted rep. If a mosfet was known to be in a series chain, then
the Minimum number would be uses.

(i.e. nominal would calculate using the Design Rules for a square contacted
S/D. Minimum would calculate using 1/2
of the Minimum Gate spacing.)


You say that you only trigger the callback by changing W. Sound like Nominal
values get populated. You could be
in for a surprise if you rely on these numbers ...
