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 Available in English, Simplified Chinese, Japanese, and Korean.
