Hi all,

How I can generate schematic from a given netlist in Virtuoso?

Cheers

What type of netlist do you have?    For CDL, you will use File--
>import-->CDL     for verilog, you need to
bring up the verilogXL tool from the "Tools" menu

Hi,

I am actually not aware of different types of netlist (e.g. as you are
telling CDL); But briefly my problem is -

I have a circuit consists of active-devices. After parsing the netlist
(netlist1) of that circuit, I am generating a netlist (netlist2) which
corresponds to the small-signal equivalent circuit of the actual
active-device based circuit. So netlist2 consists only resistances,
capacitances and voltage-controlled-current-sources (vccs). Now I want
to generate the schematic which corresponds to netlist2.

I am not aware how to do this. And again it will be great if you can
direct me how those importing is done.

Thanks,
Samiran

Hello Samiran,

i think you want to read this document:
transrefOA.pdf

Which is located in the doc directory of your local Cadence
installation directory.
<Cadence Inst Dir>/doc/transrefOA

In this document, you will find a chapter: Netlist import using
SpiceIn

I hope this will help you.

best,

bubu

In IC61X, you have File->Import->SPICE - this is more generic than the 
File->Import->CDL which was available in IC5141.

I have tried importing the netlist through File > Import > CDL...
option. But I got an error. the error msg written in ni.log file is:

############################################
ERROR (CDLIN-32): The option refLibList is not specified in the
options file /tmp/cdlInParf03455. This option is
needed to specify the list of reference libraries for master cells.

Usage error.


I provided  "CDL Netlist File" & "Output Library Name" as input and
didn't enter anything for "Parameter File", "Top Cell", "Reference
Library List" or "Device-map File". Is this causing the problem? Also
please let me know what exactly is referred to by "Reference Library
List"?

Almost certainly you'll need to provide a library containing the transistor, 
resistor, capacitor etc symbols, and a device map file to tell it how to map 
devices in the CDL netlist to components in the library.

Please read the documentation - it's in the 
<ICinstDir>/doc/transref/transref.pdf document.

Andrew.
