Problem with importing verilog to Cadence virtuoso

aamn

Hi,

I am trying to import a synthesized file.v to cadence to use it as other analog circuits.

I have wrote a verilog logic and synthesized it using YOSYS open source tool. Then I mapped it to a library called cmos_cells.lib using the same tool and I named it: xxx_synth.v.

Well, in reference library: I put basic and cmos10lpe. Those two are already added in my cadence environment libraries.

In verilog file: I put the synthesized file xxx_synth.v

In -v option: I put: cmos_cells.v. This file is part of the tech library that I used to map it in the synthesis tool.

I choose schematic option.

Now, after I import it I got only symbol view. No schematic, gates or transistors.

Please can you help:

1- what is missing?

2- Do I need after synthesizing to map it to a specific library .lib?

3- If I don't have digital library .lib that match the analog library which belong to the same technology, how can I solve it?

Thanks

    Let me rephrase my question in a short way.

    I needed to import a synthesized file to cadence virtuoso. I have mapped it to a specific technology. Though once I import it I only get the functional not the netlist. Please help?

    Maybe your synthesized verilog contains some behavioural constructs (like assign statements)?

    Without seeing what you're doing, giving an answer is pretty hard. Maybe contacting customer support would be the best option here.

    Regards,

    Andrew.
