Launching very soon · round-trip-verified, zero dependencies

SPICE netlist into a verified analog schematic.

SpiceGlass turns a raw .cir netlist into a readable, analog-convention drawing — deterministically, with no model in the loop. Every sheet is checked by re-extracting its connectivity and comparing it back to the netlist.

We're putting the finishing touches on it. Leave your email and we'll tell you the moment it goes live.

Examples

Auto-generated. Every sheet verified.

Each schematic was produced by the engine from a SPICE netlist — placed, routed, and stamped VERIFIED ✓ by re-extracting its own connectivity.

How it works

Text goes in. Every wire comes back out — traced.

The output

One netlist in.
Two files out — automatically.

Every verified schematic is written to disk as both a simulatable LTspice .asc and a pristine .svg — generated in the same pass. No manual export, no clean-up, no lock-in.
