Just give us a bit of time. We had to use some IPs that due to licensing limitations prohibited us to release the source and we were only allowed to release the bin files. We are replacing them to open source cores and we will have that part of the project available to you too. I hope you understand the situation of the project. I would love to see people adding more features to the FPGA part of it such as IRIG-B output and many other cool things that can be done. Please stay tuned.
