  1. I am trying to implement a simple JTAG chain in a Cool Runner II development board. I am taking various TDI and TDO signals and routing them in the CPLD depending on what FPGAs are powered on. I see that the CMOD CPLD board provides headers for the clock pins but no actual clock. Can I run a design without a clock if it's just simple switches inside the CPLD to interconnecting TDI and TDO signals?
