sv2v - System Verilog to Verilog

sv2v is a script that converts System Verilog code to Verilog code using commercial tools. The cdn_sv2v.sh script uses Cadence Genus while the snps_sv2v.sh script uses Synopsys Design Compiler. The commercial tools are used to elaborate the design and print out the intermediate/generic verilog before synthesis.

Usage:

Genus

cdn_sv2v.sh {top-level-name} {include-path} {output-elab-file} {output-convert-file} {file1.sv file2.sv ...}

Design Compiler Note: you will need to include umich_snps_lib.v which contains the behavioral descriptions of the low level primitives used by design compiler.

snps_sv2v.sh {top-level-name} {include-path} {output-elab-file} {output-convert-file} {file1.sv file2.sv ...}

top-level-name - This is the toplevel design that will be elaborated

include-path - A directory that will be added to paths searched for 'include files. The scripts only support a single path

output-elab-file - Output file for the elaborated Verilog untouched after running through the commercial tool

output-convert-file - Final output file after any necessary replacements and modifications

file1.sv... - Input System Verilog (or Verilog) files.

Contributing

There are several tests in the tests folder, each test contains two files:

  1. {test_name}.orig.v is the original code to be converted.
  2. {test_name}.tb.v is the testbench that will run on the original code and the converted code.

To run an individual test:

make test-{test_name}

To run all the tests:

make test

For each test run, the outputs from the testbench (running on the original and converted) be printed out.

To remove all the generated results, run:

make clean
