IP-less serializer is not working

[muzhiyun]

I had this problem today.In fact, someone else has already asked this question #33 , I use Tang Nano 9K and System Verilog 2017 like Apuder , so I guess maybe you are also using Gowin or even Lichee Tang Nano?

It seems that the author had knew about the problem through the previous issue, and Apuder provided a patch in that issue. Although the hyperlink is currently inaccessible, the modified file can still be found from https://github.com/apuder/TRS-IO/blob/nano-9k-xray/src/fpga/vg/v2.0/TRS-IO/src/hdmi/serializer.sv.

Through simple comparison, I concluded two points:

1. Apuder added define GOWINSEMImacro to solve this problem.
2. Zwenergy submitted the modification to #34 , and added the elsif GW_IDE macro in the serializer.sv file.

Therefore, I think adding define GW_IDE to the first line of the serializer.sv file can make the modification of Zwenergy take effect.In fact , the error has been successfully resolved as I supposed.

If you also use Gowin, can you try the method ?
