Each VDU decoder instance uses one interrupt (vdu_host_interrupt*). There are options in LogiCORE IP to use single interrupt per instance, and single interrupt for all instances. Clear checkbox Combine VDU Interrupt to get single interrupt for all instances. This interrupt has to be connected to either PL-PS-IRQ0[7:0] or PL-PS-IRQ1[7:0]. If there are other interrupts in the design, the interrupt has to be concatenated along with the other interrupts and then connected to the PS.
