WaveCrux

WaveCrux is a modern, high-performance waveform viewer for digital design and verification engineers. Open VCD, FST, and GHW simulation traces directly on your iPhone or iPad — review a regression during a meeting, triage a CI failure from anywhere, or walk through a trace without opening your laptop.

WAVEFORM VIEWING
• Native Rust parsing engine — large multi-million-event traces open fast
• VCD, FST, and GHW file formats
• Smooth pinch-to-zoom and pan, tuned for touch
• Full design hierarchy browser with search and filtering
• Cursors, markers, and time measurements
• Value formats: hex, decimal (signed and unsigned), binary, octal, ASCII, and enum translation

PROTOCOL DECODERS
• Serial: UART, SPI, I2C
• Buses: AXI4-Lite, APB, AHB-Lite, Wishbone
• RISC-V instruction decode
• Decoded transactions overlay directly on the waveform

GTKWAVE FRIENDLY
• Import GTKWave .gtkw session files — signal lists, groups, colors, and formats come across
• Reads GTKWave translate filter files

BUILT FOR MOBILE
• Open waveform files straight from Mail, Slack, AirDrop, or the Files app
• Layout adapts from iPhone to iPad multi-pane
• Sessions preserve your signal selections, formats, cursors, and zoom

PRIVACY FIRST
• No account, no sign-in
• Your waveform files never leave your device
• No analytics, no telemetry, no ads
