1.6.3. Make the JTAG Signal Traces as Short as Possible

Short JTAG signal traces help eliminate noise and drive-strength issues.

Give special attention to the TCK and TMS pins. Because TCK and TMS signals are connected to every device in the JTAG chain, these traces see higher loading than the TDI or TDO signals.

Depending on the length and loading of the JTAG chain, you may require additional buffering to ensure the integrity of the signals that propagate to and from the processor.
