Since the FPGA is very old, the Xilinx WebPack ISE 10.1 is the last working tool chain. You can download this legacy development on Xilinx and register for a free product installation id.
Or use mine `11LTAJ5ZJK3PXTUBMF0C0J6C4` The package to download is about 7Gb and linux based. Though I recently managed to install it on WSL for Windows 10.
There is a docker image with webpack built in which has been built which you can use to easily compile the images:
```
docker pull nhutton/prox-container:webp_image_complete
docker run -v <LOCAL_PATH>/proxmark3:/tmp --rm -it nhutton/prox-container:webp_image_complete bash
$ cd /tmp/proxmark/fpga
$ make all
```
In order to save space, these fpga images are LZ4 compressed and included in the fullimage.elf file when compiling the ARM SRC. `make armsrc`
This means we save some precious space on the ARM but its a bit more complex when flashing to fpga since it has to decompress on the fly.
