DESIGNING TARGET BOARDS FOR ETM TRACE
Because ETM trace port signals might have very fast rise and fall times—regardless of
the trace frequency—it is important that the target PCB is designed properly so it does
not distort the trace signals before they get to the connector.
For best results, it is recommended that the ETM trace signals be simulated for signal
integrity on a routed PCB by HyperLinx (or similar signal integrity SW).
