Reading INIT_DONE internally

I noticed that the user logic already starts running before INIT_DONE is asserted (about 1 us). But for example the AS_DATA Pins are controlled by user logic only after INIT_DONE was asserted.

 

So for using the SPI-Interface (/AS_DATA Pins) I have to wait until INIT_DONE is asserted.

Is there a way to check INIT_DONE internally? (as the pcb is already routed...)

 

I´m using Cyclone V GX 5.

Hi,

 

Thank you for contacting Intel community.

 

Sorry but there is no way to access INIT_DONE internally. Please refer to our KDB and pin connection guidelines:
