© Copyright 2014 Xilinx. PS interrupt setup in 2014.x The note attached to the interrupt setup tick box is misleading: It gives an incorrect idea of what is happening See on the next slide for what is actually happening

© Copyright 2014 Xilinx. Two auto-generated source files are now of interest: –Dev_processing_system7_0_0.v is a wrapper for –Processing_system7_v5_4_processing_system7.v PS7 source files

© Copyright 2014 Xilinx. This is a new parameter introduced in 2014.x. It is assigned a value in Dev_processing_system7_0_0.v and passed to Processing_system7_v5_4_processing_system7.v The parameter value passed is “DIRECT”. C_IRQ_F2P_MODE

© Copyright 2014 Xilinx. Generated PS source file in 2014.x The “DIRECT” parameter is now used in mapping the interrupt vector IRQ_F2P to the internal interrupt vector irq_f2p_i
