High Speed Signal Integrity

The use of high speed designs is becoming widespread in hardware systems. The challenge of such designs is to maintain the quality of the signals over long distances on printed circuit boards and wire-harnesses. We employ signal integrity simulation to check the effectiveness of steps taken to ensure signal integrity. After designing a system with signal integrity in mind, the verification of signal integrity is required to establish standard compliance of the design.
