Honored ContributorNIOS II reset
Dear everybody, My goal is to reset NIOS II. NIOS II owns the reset_n input and I drive this input with a signal ON-OFF-ON where the OFF state lasts 20 us with the clk signal always present...

--- Quote End --- Thanks JDHAR. But, wouldn't this only have an effect during power-up? I am not resetting the PLL's, so I would expect they would be running fine, and the lock output would be a constant '1'. Should I reset the PLL's? I typically don't even select the option to have an 'areset' input going to them.
