Fix findIVerilog Method to Resolve Symbolic Links on macOS with Homebrew

Description

This PR addresses an issue in the findIVerilog method where symbolic links (e.g., /opt/homebrew/bin/iverilog -> ../Cellar/icarus-verilog/12.0/bin/iverilog) on macOS were not being resolved correctly. This fix ensures compatibility with Homebrew installations on macOS.

Changes

1. Symbolic Link Handling:
   • Updated to resolve symbolic links to absolute paths, ensuring correct execution even with relative links.
   • Added .normalize() to clean up paths.
2. Logging Improvements:
   • Replaced System.out and System.err calls with LOGGER.
   • Added debug and error logs for better traceability and diagnostics.
3. Fallback Mechanisms:
   • Retains existing behavior but enhances it with safer path resolutions.
4. Removed Hardcoded Debug Outputs:
   • All debug information is now logged via the Logger instance.

Impact

• Fixes issues on macOS systems using Homebrew where iverilog could not be detected due to symbolic link resolution failures.
• Improves maintainability with better logging practices.

How to Test

1. Ensure iverilog is installed via Homebrew on macOS (brew install icarus-verilog).
2. Confirm the symbolic link in /opt/homebrew/bin/iverilog points to the correct target.
3. Run the updated method to verify it correctly detects iverilog.
