Quartus 23.3 "Channel closed" error - Quartus 23.3 "Channel closed" error Hi, I am using Q23.3 and it throws a "Channel closed" error after running BER test for a while (~5/10 mins). I am running BER test for PAM4 channels. I have tried downgrading the JTAG blaster speed from 24MHz to 6MHz, but this did not help solve the issue Please advice.
