Title: read spice into DFII
Post by sandy on Jul 2^nd, 2003, 1:10am

Hi,

I need to read spice into DFII. I have tried to import the spi using import CDL. It imported the netlist, but in the schametic, I can see nothing.

I have tried to give reference library, but not working either.

Anyone has some experience about it?

Thanks a lot for your comments

hi,

Some update.
I have tried to specify the schema lib. I can see the trasistor now. but they all stacked together and can not move.

any idea?

Sandy,

The Import-CDL route does not create an editable
schematic. The resulting cellView contains all the instances
and connectivity (i.e. the logical information), but
not physical information.

It's netlistable, but not editable as a schematic.

There's an enhancement under way to produce
a real schematic from the imported data as part
of the CDL import - and also to provide greater
control (greater than none, that is) over the mapping
of devices.

Currently we have a couple of services solutions available
if you need something now - which can create an
editable (yet perhaps not terribly pretty) schematic
and take care of mapping of transistors to a particular
design kit.

It _can_ be made to work, but usually requires some
effort (and often SKILL code) to be truly successful
with it as it stands right now.

Regards,

Andrew.
