Interactive Waveform Viewer

SiliFlow embeds a native waveform viewer directly in the bottom panel or editor tab strip—eliminating context-switching to external windows for day-to-day verification.

1. Supported Formats & Rust wellen Parser

• Powered by the native Rust wellen parser (commands/waveform.rs), supporting both VCD (.vcd) and FST (.fst) waveform traces up to 100 MB (with automatic fallback line-parser recovery for malformed VCD headers).
• Hold Alt while clicking Waveform in the Action Island (Alt+Click) to open waveforms directly in the secondary split pane beside your RTL code.

2. Key Capabilities

• 1-Bit & Multi-Bit Bus Rendering: Clear digital transitions for scalar nets and packed vectors, with red X unknown-state hazard highlighting and amber Z high-impedance highlighting.
• Radix Switching (HEX / BIN / DEC / OCT): Switch global bus representation cleanly across Hexadecimal, Binary, Decimal, and Octal.
• Dual Measurement Cursors (Cursor A & Cursor B):
  • Place and inspect independent primary/secondary time markers (Cursor A, Cursor B).
  • View exact timestamps, ΔT delta, and derived frequency (Hz / kHz / MHz / GHz), alongside live hover cursor time tracking.
• Collapsible Scope Tree & Signal Filter: Resizable signal sidebar (70–450px, saved across sessions), expandable DUT hierarchy scopes, scope dropdown filter, and substring/regex signal filter.
• Go to Signal Definition & GTKWave Handoff: Jump straight from a waveform signal to its RTL declaration via VerilogWorkspaceIndex, copy signal names/paths/values, or open huge external runs directly in GTKWave from the Run menu (Run → Open in External GTKWave).
