Title: schematic to Verilog-A
Post by rajdeep on Dec 9^th, 2008, 3:35am

Hi all,

Is there a way to convert a schematic into a structural Verilog-A code.
Say, I connect 3 blocks A, B and C in some way using Cadence Schematic Editor.
Now is it possible to translate this scheamtic into an equivalent verilog-A view?
The inbuilt view translator doesnt work!

One easy way cud be translatng the spectre netlist into an equivalent verilog-A netlist using
soem scriptng, but the script is failing at time...so in the lookout for a robust code or available
tool for this! Otherwise, it is abs nightmare to wire those big netlists manually!

You can do such netlisting by using NC-Verilog or Verilog-XL integration in ADE.
This means netlisting by netlister for Verilog-D.
But you have to force netlister to stop before transistor level.
Here you have to specify any virtual stop view for lowest blocks which include transistor, resistor, etc.

Or you can use the cell-based Verilog-AMS netlister to do this. If you use Tools->AMS->Netlist in the CIW, you can specify a cellView. It will create the netlist within the cellView directory, so you can find it there...

This doesn't need any switch/stop view setup (because it only netlists a single cellView), but if you have primitive devices in the schematic, it would need ams simInfo in the CDF (this isn't needed for blocks though).

Andrew.
