Signal Integrity Analysis

Advancements in high-performance microprocessors and access to high-speed internet is driving the need for compact, high-performance systems that offers reliable data transmission with superior signal integrity.

OVERVIEW

The demand for high speed, compute-intensive devices in compact packaging call for higher density PCBs. The advent of high-performance microprocessors and high-speed interfaces are greatly driving the need for high-performance gadgets that offers reliable high-speed data transmission.

These advancements are posing a challenge to designing boards with superior signal integrity and Signal Integrity Analysis Services. Over the past decade, microprocessors and chip fabrication technologies have evolved tremendously. However, PCB fabrication technologies lagged, impacting the overall system performance. Signal Integrity Analysis is one of the most important factors that pose a challenge to design engineers.

As signal integrity affects the electrical performance of the system, it is crucial to have a robust SI analysis methodology in place during the product development process. Negligence to Signal Integrity can result in various issues such as crosstalk, reflection, EMI and signal distortion among others.

In a complex PCB, signals travel between various devices such as processor, memory chips, connectors, etc. interconnected over the signal traces. The nature of these interconnecting signal traces has a high impact on the integrity of the signal being transmitted.
