Adding D and Q ports to Sim waveforms

From the Assignments Menu, Select Assignmenst editor to bring up the Assignments editor window.

Under the Assignments Name Column in a new row you can find the "Add D and Q ports of register node to Simulation Output Waveforms" option.

You can then apply it to whatever nodes you like.

I have to say I have never used this option!

the help says

"....A logic option that adds the D and Q ports of a register node to the list of signals in the output waveforms that are shown in the Simulation Waveforms section in the Simulation Report after a successful simulation.

This option is useful because it makes the D and Q ports of a register node observable during a simulation.

The option must be assigned to a register node or it is ignored. This option is available for all Altera devices..."

Hope this helps
