lvsIgnore / lxRemoveDevice for K2 Chameleon

C

Guest
I have a schematic with analoglib resistor instances for simulation.
I want those instances to be ignored and treated as shorts for layout
and verification. lvsIgnore and lxRemoveDevice work great for layout
in VirtuosoXL, so problem #1 is solved. On this project we're using K2
Chameleon tools for verification, however, and it will ignore the
device instances, but leaves them as an open. Is there a similar device
parameter like lxRemoveDevice that will cause Chameleon to short these
instances' PLUS and MINUS pins?
 
What databases does K2 Chameleon use for physical verification,
Cadence cdba or cdl and gsd2?

I'm not sure. It does a translation of the schematic and layout to SV
DB (SVER).

For a CDL netlist there is a SourceLink solution, but this wouldn't help you?!

Maybe there is a command in K2 Chameleon to filter specific devices as
shorts, Assura LVS can do so!

Cody,

You can modify the SVER model name of the device to something
unique(which is not found in the rules file)

For example, you can call it RESISTOR_K2_SHORT and then you can delete
the device using K2 SVCOMPARE OPTIONS file.

In the "DELETE DEVICE" options you can add the "SHORT=YES" for this
particluar model name.

Plese let me know if you need any clarifications.

Regards,
Mohan R
