It's been a few years since I mentioned the rise of China in the supply of original components. GoWin is one of those companies that for several years has developed a series of FPGAs.
So I thought it was time to try this type of components. For this I managed to get the programming tool GWU2X :
The development software tool is available directly on the GoWin site. I also had to find a development board equipped with an original GoWin FPGA. I couldn't really find what suited me on the market, so I decided to develop my own board, in Qmtech format, since I had developed a few projects with this board format:
Very recently, I managed to implement the 'Hello World' (the blinking led) on this board. The next step was very ambitious, namely trying to implement a complete Z80 system within this FPGA.
So, I chose to try installing the Microprofessor version 1B system on the electronic board dedicated to this small vintage computer:

So, after a few hours of work, the result is there:
