Add the serial ports of JESD204B to SignalTap, but compile failed.

I don't know anything about this IP, but it looks like you're trying to tap something that goes to I/O pins so it can't be both routed to the pins and routed to the core logic for the logic analyzer. In situations like this, you should tap the internal signal that drives the register or logic that drives the pin.

Thanks, I'll try the register or logic.
