Figure 7. Assign SignalProbe Pins Dialog Box
When reserving SignalProbe pins, you can also use the register pipelining
feature to ignore jitter, to force signal states to output on a clock edge, or to
delay a signal output. You can also use register pipelining to synchronize
multiple SignalProbe outputs from a bus of signals, or to prevent
SignalProbe routing from becoming the critical path because of f
MAX
changes.
If the Compiler cannot route SignalProbe signals during a SignalProbe
compilation, you can allow the Compiler to route SignalProbe signals by
modifying the modify the latest fitting results.
You can also use the SignalProbe feature with Tcl. With Tcl commands, you
can add and remove SignalProbe assignments and sources, perform a
SignalProbe compilation on a design, and compile routed SignalProbe
signals in a full compilation.
