Pinmux Web Tool

Purpose-built for hardware teams, the Pinmux Web Tool enables planning and validation of pin usage across MCU and FPGA families. It models a pinmux matrix to evaluate feasible mappings, detect conflicts, and propose optimized configurations. The tool covers common peripherals (UART, SPI, I2C, PWM) and supports alternative functions, drive strength, IO standards, and shared-pin constraints. The core logic translates device data into a constraint-satisfaction problem, solving for assignments that satisfy per-pin limits and peripheral requirements, then presenting one or more viable mappings with a recommended option. Users benefit from rapid iteration on device selection, package choice, and routing strategies, reducing design cycles and lowering risk during bring-up and field updates. Advanced users can run batch scenarios, export mappings for documentation, and integrate results into design logs. The tool focuses on mapping correctness and basic electrical constraints, not on full timing analysis or detailed signal integrity. It is suitable for electronics engineers, PCB designers, and verification teams seeking deterministic pin usage insights and auditable design records.
