Abstract

See full text

A programmable logic integrated circuit device has several features which help it perform according to the PCI Special Interest Group's Peripheral Component Interface ('PCI') signaling protocol. Regions of programmable logic within the device are closely coupled to the data signal output pins and clock signal input pins such that delay between application of a clock signal to the device and output of a data signal from the device is within PCI signal standards for delay. The device also includes output circuitry that can be configured to selectively invert signals to output enable and data input enable terminals of the output circuitry.
