creating a schematic file from a netlist file

Srinivasa,

Why would you want to write a SKILL program to do this? Both File->Import->Verilog and File->Import->SPICE (IC61) or File->Import->CDL (IC5141) will do this for you from different netlist formats.

It seems a bit unnecessary reinventing a standard capability...

Regards,

Andrew.

Hello Andrew,  hello Srinivasa,

I had asked myselft one day if I should develop a netlist parser, without knowing it allready exist un Cadence. However, I dit not succeed in importing a simple spectre netlist with the spice In Import (IC6).

 I tried to import :  /soft/cadence/IC610/tools/dfII/samples/artist/OCEAN/opamp741Char/design/netlist

 But it fails, spiceIn.log issuing :        

 Master Cell: 'capacitor'.
        Master cell CDF data not found for 'sample.capacitor'
        Did not find 'basic.capacitor:symbol'.
        Did not find 'analogLib.capacitor:symbol'.
        Did not find ANALOG_TUT.capacitor:schematic.
ERROR (SPICEIN-24): Spice In did not find the symbol view of the master cell 'capacitor' of the instance
'c5' in the subcircuit 'opamp_g1'. Specify the reference library that has the symbol
view of the master cell, or use device-mapping to map 'capacitor' to a different
cell.

 Is there a tutorial that explainshow to use it? It seem simple, but for me it simply failled...

Did you try reading the documentation? You'll almost certainly need a device map and a reference library. I don't think there's a tutorial, but the documentation exists... the Help button on the File->Import-SPICE form takes you to the right manual.

I think there are a number of solutions on this on Cadence Online Support. Here's a simple one - there are others.

Andrew.

 Thanks, It shows me that I indeed have to map:

devselect := resistor res
devselect := capacitor cap

 I allready added analogLib to the 'Reference Library List', but I added 'basic' too, which seams to be not a good references library for capacitor.

Thanks it worked.

 I haveaccidently deleted my schematic File (sch.cdb) but i have the netlist file 

 I tried to use File->Import->CDL In

I dont know exactly how to do it ........But i tried and i didnt specify any thing in Parameter File and Device map File

I got ni.log files Which was as below

What do i do...........or any you suggest any better way

pl help

Venkat,

Well, File->Import->SPICE will do this - although how "human readable" it ends up being is a matter of opinion, I guess. There is the "analog schematic generation" option which tends to produce better schematics for analog circuits (this is an option on the Import SPICE form).

Did you try using the SPICE import?

Andrew.

I can  get spice net list from RTL.  How  do a get a spice netlist into Cadence composer ?

Hmm. You post a question on a 6 year old thread (suggest you read the forum guidelines), but what's stranger is that the post you replied to actually answered your question...

The  only company  I know that take a netlist and make is  schematic  is SpiceVision  from Germany. (www.concept.de) 

I was  hoping   Cadence had a tool  for  this.
