I am looking to create a skill program which could generate a schematic file from a given netlist file(present in text format).
netlist will be more of digital gate instances connected together.
Does anyone have idea or process how it can be done? A sample code would be great help.
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...
In reply to Andrew Beckett:
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 symbolview of the master cell, or use device-mapping to map 'capacitor' to a differentcell.
Is there a tutorial that explainshow to use it? It seem simple, but for me it simply failled...
In reply to ebecheto:
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.
Thanks, It shows me that I indeed have to map:
devselect := resistor resdevselect := 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
