8 years agoIf you are constructing your own custom GPIO and Timer modules, then you can also customize their interfaces to include Avalon Interrupt Sender/Receiver and have the modules connected directly when you construct the system in Qsys. There is no need to have NIOS [and software] involved in the triggering you are describing.
Also, you can use "Conduits" to make more flexible/complicated connections, in case what you're trying to accomplish can't be done with interrupts.
