Scanalog: Interactive Design and Debugging of Analog Circuits with Programmable Hardware
summary
Interactive tool that programs a real FPAA together with a digital oscilloscope and an arbitrary waveform generator to let users reconfigure analog hardware live, view internal traces, record/replay inputs, and run unit-style assertions. It reverse‑engineers FPAA memory to map GUI modules to subcircuits, uses time-multiplexed scanning of a single scope (trading per-node refresh for circuit size), demonstrates a proximity-sensor, EKG and audio mixer that all function, and an informal study where 8 users succeeded. Exports to PCB tools and supports custom JavaScript assertions.
