About:
Surfer is a modern, cross-platform waveform viewer designed for digital logic simulation analysis. It efficiently handles large VCD, FST, and GHW files, providing a responsive user interface for navigating complex signal traces. The tool aims to offer a streamlined alternative to legacy viewers with improved performance and usability.
Key Features:
  • Supports VCD, FST, and GHW formats
  • High-performance rendering for large waveforms
  • Modern Qt-based user interface
  • Cross-platform (Linux, macOS, Windows)
Use Cases:
  • Debugging FPGA/ASIC simulation results
  • Analyzing signal timing relationships
  • Inspecting hardware design behavior
Alternatives:
  • gtkwave – Legacy tool; Surfer offers a more modern interface and potentially better performance
  • sigrok – Focuses on hardware logic analyzers; Surfer is specialized for simulation waveforms
