Pyverilog-based verification/design tools

Project Description


Pyverilog_toolbox is Pyverilog-based verification/design tool including code clone finder, metrics calculator and so on.
Pyverilog_toolbox accerating your digital circuit design verification.
Thanks to Pyverilog developer shtaxxx.

Software Requirements

- Python (2.7)
- Pyverilog (you can download from
Pyverilog requires Icarus verilog.


If you want to use Pyverilog as a general library, you can install on
your environment by using

If you use Python 2.7,


python install

Or you can use pip


pip install pyverilog_toolbox

Python 3.x is not tried by author.



codeclone\_finder can find pair of the register clone, which always hold
same value. Also can find pair of the invert register, which always hold
different value.

Combinational logic loop is sticky problem, but you can find it by
combloop\_finder easily.

Unreferenced\_finder can find signals which isn't referenced by any
signals. By using this, you can delte unnecessary codes.

metrics\_analyzer is metrics measurment tools for Verilog HDL. You can
visualize complecity of module/register/function/.

regmap\_analyzer can analyze register map structure from RTL. After
install Pyverilog\_toolbox, you can use regmap analyzer by this command.

cnt\_analyzer analyze counter property(up or down, max value, reset
value and counter dependency). And extracting event which depends on
counter value. This feature help you finding redundunt counter, deadlock
loop, and other counter trouble.
