Hi.
I design a xilinx virtex2pro with pci-x interface that is connected to a server PC. I am using the PCI interrupt. Whenever an interrupt is completed the my fpga drive it to 'Z' and the pullup on the mother board pulls it to '1'.
The problem is that the pullup is very slow (300 ns) and the host interrupt service routine is accessed again for nothing.
I am using IOB type PCIX.
Am I doing something wrong ?
ThankX, Nahum
