WaveCrux vs Pocket VHDL

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. WaveCrux is also available for macOS, Windows, and Linux — visit wavecrux.app to learn more.

Pocket VHDL is an offline VHDL code editor for iPhone and iPad. Open, edit, and save .vhd and .vhdl documents through the Files interface. Syntax highlighting distinguishes keywords, types, strings, numbers, and comments, while document-aware completion helps you reuse declarations from the source you are editing. Features • Create, open, edit, and save .vhd and .vhdl documents • Highlight VHDL keywords, types, strings, numbers, and comments • Complete signals, variables, constants, types, and VHDL language items • Find, move between results, replace, and replace all • Show line numbers and go directly to a line • Navigate entities, architectures, processes, and declarations in the symbol outline • Use automatic indentation and paired brackets or quotes • Access a mobile coding toolbar and hardware keyboard shortcuts • Adjust font size, tab width, and editing behavior • Work in portrait or landscape on iPhone and iPad Pocket VHDL requires no account and includes no advertising or user tracking. Document contents are not sent to a developer-operated server. The current version focuses on code editing and does not compile or simulate VHDL.
