Spartan-6 FPGA Integrated Block Wrapper v1.1 for PCI Express - Clock-to-out delay required on cfg_interrupt_n for simulation

Description

There is an issue in the simulation model for the Spartan-6 FPGA Integrated Block for PCI Express which causes the simulation to hang if an interrupt is transmitted and there is no clock-to-out delay modeled on the cfg_interrupt_n pin.

Solution


A delay of 1ps or greater is required. A work-around is included in <component name>/source/<component name>.v. This file is generated as part of the files delivered by CORE Generator.
