Technique for determining performance characteristics of electronic devices and systems

摘要

A technique for determining performance characteristics of electronic devices and systems is disclosed. In one embodiment, the technique is realized by measuring a first response on a first transmission line from a single pulse transmitted on the first transmission line, and then measuring a second response on the first transmission line from a single pulse transmitted on at least one second transmission line, wherein the at least one second transmission line is substantially adjacent to the first transmission line. The worst case bit sequences for transmission on the first transmission line and the at least one second transmission line are then determined based upon the first response and the second response for determining performance characteristics associated with the first transmission line.

1. A transmitter integrated circuit for use in a signaling system in which the transmitter integrated circuit is to be coupled to a receiver integrated circuit via transmission lines that form a digital bus, the transmitter integrated circuit comprising:
data transmitters to each transmit data over respective ones of the transmission lines to the receiver integrated circuit; each of the data transmitters to transmit in parallel a test data signal to the receiver integrated circuit to determine a performance characteristic of the signaling system.
