VLSI-Linter

VLSI-Linter is a debugging and linting tool designed to assist in identifying and resolving errors in VLSI design flows. It parses log files, interacts with an error database, and provides both command-line and graphical interfaces for efficient debugging.

Features

• Log Parsing: Extracts and analyzes error messages from log files.
• Error Database Interaction: Interfaces with an error database to provide detailed error information.
• Command-Line Interface: Offers a CLI for quick debugging tasks.
• Graphical User Interface: Provides a GUI built with Tcl for interactive debugging sessions.

Usage Run the Debugger

To launch the debugger (CLI or GUI), simply run: ./run_debugger.sh

Run Python Debugger directly

python debugger.py

Sample Input and Output Input

The sample_log.txt file contains entries like:

ERROR: Net 'clk' has multiple drivers. WARNING: Unconnected input port 'reset' on module 'counter'.

Output

Running the debugger will produce output similar to:

Identified Errors:

1. Net 'clk' has multiple drivers.
   • Suggested Fix: Ensure 'clk' is driven by only one source.
2. Unconnected input port 'reset' on module 'counter'.
   • Suggested Fix: Connect the 'reset' input to the appropriate signal.
