Abstract

PCI Express is high-speed point-to-point serial protocol, the system is designed by analysing loss and jitter through Eye Diagram. It is necessarily analyzing high speed serial signals when the PCI Express Gen3 which has 8Gbps physical signal speed is designed especially. This paper deals with topology extraction, channel analysis, extraction of s-parameters and system signal integrity simulation within transceiver buffer models through PCI Express Gen3 server connecting switch system design. Optimal parameters of transmitter buffer equalizer are found through solution space simulation of de-emphasis and preshoot parameters to compensate channel loss.

PCI Express는 고속 차동신호를 사용한 점대점(point-to-point) 프로토콜로 시스템 설계 시 Eye Diagram을 통한 신호의 손실(Loss)과 지터(Jitter) 분석이 필요하다. 특히 PCI Express Gen3 물리 신호는 8Gbps의 고속 직렬신호로 고속신호분석에 의한 시스템 설계가 반드시 요구된다. 본 논문은 PCI Express Gen3 서버 연결망 스위치카드 시스템 제작을 통하여 고속 직렬신호의 토폴로지 추출, 채널분석, 채널의 S-파라미터 추출 및 송수신 버퍼를 포함한 시스템의 신호분석 시뮬레이션을 다룬다. 채널의 손실을 보안하기 위해 수신단 Eye diagram 분석을 통하여 송신 버퍼의 이퀄라이저 파라미터를 조정하여 송신단 최적의 De-emphasis와 Preshoot 파라미터 값을 시뮬레이션을 통하여 찾고 있다.
