Instance configuration with analog simulation under spectre

[Hannes]

Hello,

I want to use one analog testbench cellview (for doing a spectre
Simulation controlled by an Ocean Script) for a couple of different
versions of one "DUT" instance.

Do somebody know, if there is a way to replace one instance in a
hierarchical cellview (like configurations in vhdl)?
I don't want to handle 6 (that's the number of my different chip
versions) copies of the same testbench cellview.

Best regards

Hannes

Hi Hannes,

Could you use the hierarchy editor to do this? Then you could create 6 different
configurations of the testbench - and then point to the config when simulating.

Note that this would depend on the different versions being different views of
the DUT cell.

You could also (if you didn't want to manually create the config) use the hdb.*
SKILL functions to build the config dynamically and then use that in your OCEAN
script.

Regards,

Andrew.
