Solution Overview

Problem

It is challenging to directly generate and simulate power supply noise on the power plane of a printed circuit board in a laboratory setting, which is essential for observing and designing effective power transmit systems for IC chips.

Innovation Solution

A noise simulation system comprising a signal trace and a signal generating circuit is used to induce a simulated noise on the power zone block of a substrate. The signal generating circuit transmits an alternating current signal over the signal trace, which determines the waveform of the simulated noise, allowing for the simulation of power supply noise in actual conditions.
