Hi Alex


For the "Interrupt Sender Properties", it is the minimum required signals that needs to be present in your custom IP.

If you refer to the timer IP, the timer IP there is a reset input signal, clock input signal, avalon input signal and interrupt output signal.

You could leave the avalon signals unconnected, it should be able to run.

It is required to access the register or set settings from the avalon master.

Jingyang, Teh

Hi,

For my custom IP, I set some inputs as well:

input: 16bit control register, 16bit timer flag register

output: 16bit timer irq signal.

Please correct me if Im wrong:

In that case, if I want to control the timer in my usersapce & kernel space, I have to use Avalon MM bridge.

And my interrupt setting(the sender setting in platform designer) can be keep blanked?

Thank you

Reguards.
