Open Source FPGA Tooling, Our Journey from Resistance to Adoption
summary
Company moves its FPGA toolchain from proprietary to SymbiFlow and open source repos and demonstrates a working QuickFeather board running qorc-sdk that loads FPGA bitstreams at boot. Gateware implements USB-serial and two extra UARTs to link a PM2.5 sensor and a LoRa radio, sending base64 payloads over a gateway; bitstream build integrates into the normal make flow and recompiles on-device in ~10 ms. Work takes about a year with partners, enables ADC sampling, convolution offload, and sub-10 mW operation.
