GPU-accelerated rendering
Hierarchical LOD over millions of transitions. OpenGL 3.3. Smooth at 60 FPS on multi-gigabyte traces.
T₀ // routewave · waveform viewer
Read the trace.
A GPU-accelerated waveform viewer for digital-logic engineers. Decode bus protocols inline, diff a failing run against a passing one, drive every action from a scriptable console. One binary. No seat licenses.

Everything you need to debug hardware — in one tool.
No subscriptions. No feature gates. Every capability ships in every release.
Built-in protocol analyzers
UART, SPI, I2C, AXI-Stream, AXI4, valid/ready handshake. Decoded inline on the waveform — not in a separate pane.
Scriptable console
70+ commands with autocomplete, aliases, macro recording (.ltr). Every GUI action has a console equivalent.
Waveform diff
Load two VCDs. Overlay every transition that disagrees. Find the regression edge in seconds.
Virtual signals + bus tools
Expression engine (AND / OR / XOR / NOT / edge / arithmetic). Virtual bus grouping. Bit slicing. Hex value search.
