VX-171 · Signal Router Reference Design

Every idea is a net.
We route it to the pin
that needs it.

Vireo Labs builds documentation systems for hardware teams — where a spec, a revision note and a failing test all live on the same trace instead of three different tabs.

U1

Intake stage

Capture the signal before it decays

Hardware knowledge arrives as noise: a Slack thread, a scope photo, a whiteboard from a standup that three people remember differently. Intake buffers all of it into one net and holds it at a known level until someone is ready to route it.

  • NET_IN0
  • NET_CLK
  • NET_D3
  • NET_VDD
Buffered 12 sources

Threads, tickets, bench logs and CAD comments land on the same rail.

Latched 0 loss

Nothing is discarded before a human assigns it a destination pin.

U2

Routing fabric

Length-matched paths, not folders

A folder tree assumes every document has one home. A board assumes every signal has many destinations and one impedance budget. Vireo routes each note as a net with declared endpoints — the spec pin, the test pin, the manufacturing pin — so a change propagates instead of getting filed.

  • NET_CLK
  • NET_D3
  • NET_GND
Differential ±2 mil

Paired revisions travel together; a spec never lands without its test.

Plane Layer 2

Shared context sits under everything as an uninterrupted reference.

Stitching 64 vias

Cross-team handoffs punch through layers instead of routing around.

U3

Netlist

Continuity report, rev D

Hover any row or any pad above — the whole net lights up across the board, including the copper between modules. This is the same connectivity model the routing fabric uses; there is no separate index to keep in sync.

Put a probe on your own stack

Send us a net name and we will route a sandbox board against your repo within a working day. No connector required — we bring the harness.
