Generated single flat AMS netlist

Hi Andrew and all,

I have an AMS design inside Virtuoso. My top level config view has mix of schematic, spectre, verilogams and verilog views. I want to generate single command line netlist of this design. My final goal is to encrypt this netlist and send it to third party. I believe, generating single AMS netlist will make encrypting easier.

Right now, I am generating command line AMS netlist from ADE (ADE->Export->Simulation scripts for irun). This creates a self contained netlist directory in unix terminal. It has single netlist.vams file. However all text files(verilog and verilogams) are present in their individual cell directories and referenced in "irunArgs" text file using -f switch.

Is there a way I can dump a single netlist.vams file which will append all verilog verilogams file content in the same netlist. Then I can just encrypt this single netlist file and pass it to third party?

I'm using AMS-UNL netlister, IC618 ISR4 and Xcelium 19.03

No, not as far as I know. You'd have to assemble it yourself, but that's not going to be possible because you can't have multiple languages in a single file (I didn't notice that when I started typing this!). So no is definitely the answer, even assembling it yourself wouldn't be possible.

Sorry.

Andrew.

Hi Andrew. I have only verilog and VerilogAMS languages in my design. ADE already generates netlist.vams file. Since vams is superset of verilog, I don't think single netlist.vams file would be an issue?

Possibly, unless you use any reserved Verilog-AMS words in the Verilog code. It's probably OK though, but you can check that by assembling it yourself and trying it out, I guess. It doesn't make any sense for Cadence to provide an option to do this because it would only work in a narrow set of circumstances.

Regards,

Andrew.
