Hi Brian,
"Warning(18395): "Low Speed Viterbi Decoder" does not support the Intel FPGA IP Evaluation Mode feature"
Can you check by disabling the evaluation mode?
Refer the "1.6 Disable Intel FPGA IP Evaluation Mode" from following link,
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an320.pdf
"Warning(115005): Unlicensed IP: "Low Speed Viterbi Decoder(6AF7 0038)"
also check the license status,
Refer the "1.2 Viewing IP Core License Status " from above link.
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
Best Regards
Vikas Jathar
