create schematic from netlist ?

[Prasanna Tamhankar]

I have a netlist created by Analog Artist, is it at all possible to load
this back as a schematic (assuming I just have the netlist file and no
schematic database) ?

What I am asking for is the reverse process for netlist creation from Artist
(Simulation->Netlist->Create)..

Thanks,
Prasanna

There's not really a backwards process - there is CDLIN which can read a CDL
(which is spice like) netlist, and produce a schematic, although it is a bit
limited at the moment because it can't map the devices to whatever PDK you're
using. The schematic generation was added in IC5033 (I think that's when it came
in) - prior to that you get a netlistable view which isn't an editable
schematic.

Wouldn't it be better to get the original schematic - you've lost an awful lot
of information (useful positional information, for example, which would make
the design easier to comprehend) when the design was netlisted?

Regards,

Andrew.

I've used the CDLIN mentioned above in the IC5033 suite of DFII.
Basically CDLIN places and routes the transistors on a grid pattern.
This works fine for my purposes.

However, as Andrew said, CDLIN generates a funky schematic.
I find the distance between devices is large and regular in
a matrix manner. There may be settings to control this, but
I haven't bothered to use them as the schematics I have are
all huge digital blocks which we change all the time in text,
so I don't need to often mess with the schematic.
