The GOWIN ecosystem continues to be adopted by the open-source FPGA community!
Support for GOWIN FPGAs has been added to the popular FPGA debug toolchain!
fCAPZ is an open-source, vendor-agnostic suite of FPGA debug cores, including, among others, an Embedded Logic Analyzer (ELA) for waveform capture and an Embedded I/O (EIO) for runtime read/write of fabric signals. Coupled with OpenOCD, fcapZ opens up a new realm of debugging possibilities:
* No more fiddly, platform-specific, GUI-based configuration of debug cores.
* No more interrupted synthesis / PAR flow for debug core wire-up.
* Simple plug-and-play debug cores, platform-agnostic interface.
* Command line-based, i.e. probe, capture, with a multitude of debug options.
* Automated, AI-based review of debug capture
* Allows waveform review using open-source viewers such as Surfer or GTKWave.
For those wishing to see fcapZ in action, BrisbaneSilicon has integrated it into the example project for their popular BRS-100-GW1NR9 FPGA development board!

The adoption of the GOWIN ecosystem by the open-source community is continuing, making FPGA access even easier.
