VerilogPADAnalyzer

VerilogPAD is Python tool designed to analyze Verilog files, providing power, area, and delay metrics. It is also released as a PyPi package under the name verilog-pad-analyzer (https://pypi.org/project/verilog-pad-analyzer/).

You may simply import it into your Python project by installing this package witht the command

$ pip install verilog-pad-analyzer

Prerequisits

• Install the following tools:

1. Python
2. Linux
3. Yosys: link (https://github.com/YosysHQ/yosys)
4. OpenSTA: link (https://github.com/The-OpenROAD-Project/OpenSTA)
5. Icarus Verilog: link (https://github.com/steveicarus/iverilog)

Note: add the binaries of 3, 4, and 5 to your PATH

Features

• Comprehensive Analysis: Compute detailed metrics for power consumption, physical area, and timing delay of Verilog circuits.
• Intermediate File Handling: Automatically manages intermediate files in a temporary directory to keep the workspace clean.
• Report Generation: Outputs analysis results in separate, organized report files for each metric.

Folder Structure

• ./config/: contains the technology library and synthesizer scripts
• ./src/: contains the main classes and modules of the project
• ./VerilogPDA.py.temp/: a temporary folder that is automatically created and stores the intermediate files such as synthesized files (can be safely removed afterward).
• ./VerilogPDA.py.report/: a temporary folder that is automatically created and stores the area, power, and delay reports (can be safely removed afterward).

Usage

To run the VerilogPADAnalyzer, use the following syntax:

Arguments

$ python3 VerilogPDA.py [path-to-input]

For example, assuming that a circuit called abs_diff_i4_o3.v is located at the root directory, one can get the area, power, and delay reports of this circuit using the following command:

$ python3 VerilogPDA.py abs_diff_i4_o3.v

Upon launching the command above, three report files will be generated in ./VerilogPDA.py.report/ directory.
