JITX

Founded 2018

Design printed circuit boards using code and automated simulation checks

You can use JITX to design printed circuit boards by writing Python code instead of drawing them manually in traditional CAD interfaces. The system converts your manufacturing rules, board stackups, and signal integrity targets into programmatic hardware designs. Code edits are automatically generated and evaluated using electromagnetic simulation with tools like HFSS. Engineers can inspect generated schematics, review board routing, and execute rule checks directly on their local machines, allowing teams to iterate on high-frequency electronics and production-ready layouts with fewer manual drafting mistakes.

What JITX does

Generate circuit schematics from Python scriptsAutomate electromagnetic simulation setups in HFSSRoute high-speed traces and assign connector pinsDefine layer stackups and fabrication constraints in codePerform automated design rule checks on PCB layoutsEvaluate return loss and mode conversion metricsTranslates Python code into circuit schematics and layout geometriesRuns HFSS electromagnetic simulations automatically in a feedback loopExecutes locally on internal infrastructure to maintain design securityAutomates pin assignments, fencing, and signal trace routingIncorporates manufacturing stackups and tolerances directly into design codeValidates high-frequency signal integrity metrics against engineering targets
