Zynq-7000, Processing System 7 - PL to PS interrupts changes and migration flow from 2013.x to 2014.x Vivado

Description

The zynq PL can interrupt the PS via the IRQ_F2P port.

When more than one interrupt needs to be used in the PL, a CONCAT IP block is added as a shim between the interrupt sources and the PS IRQ_F2P port.

Changes have occurred in this IP, as well as in the PS wrapper code, that modify the interrupt mapping done in Vivado 2014.x compared to the 2013 version.

 

Please read the presentations attached for a detailed explanation. 

The presentations also cover how to migrate a design from 2013.x to 2014.x and what to expect when doing so.
