LogicCircuit Checks Exported Verilog Across 46 Suites

LogicCircuit exports its visual designs as Verilog and checks 46 test suites against the generated result.

Thesis connection

A circuit drawn in an interactive tool can enter a standard chip flow without losing its behavioral tests.

LogicCircuit can now export a visual circuit as structural Verilog, the standard text format that describes connected hardware blocks. It supports generic cells and the SkyWater 130-nanometer cell library, so the same drawing can become a portable simulation model or input to an open chip-layout flow.

Export alone would only move the trust problem. LogicCircuit also generates Icarus Verilog test benches from its existing circuit tests and compares the exported behavior with its own simulator. All 46 suites match across four export variants. As a harder check, its 2,181-cell eight-bit computer reaches a design-rule-clean layout in OpenROAD, meaning the generated design obeys the manufacturing geometry rules.

That combination makes the visual editor more than a teaching front end. A builder can sketch logic, keep the behavioral tests, and learn where the design fails in a real layout tool. The next useful test is whether a design that passes this path can run unchanged on a small fabricated chip.
