Abstract

An accurate signal integrity verification method based on high-frequency measurements is proposed. For practical transmission lines that require a package process, process variations metal roughness and skin effects and boundary conditions may have deteriorative effects on circuit performance. These effects are represented in terms of parameters that can be readily utilized for field-solver. Thereby a more accurate signal integrity verification using field-solver can be achieved. It is shown that in both single and coupled lines the signal transients using the proposed method have excellent agreement with the measurement data.

본 논문은 실험적 고찰을 통해 고주파 전송선 회로의 시그널 인테그러티를 정확하게 검증하는 방법을 제시하였다. 패키지 공정을 이용하여 제조한 배선의 공정편차, 표면 거칠기 효과, 표피 효과, 시뮬레이션을 위한 경계조건 등은 시뮬레이션의 정확도에 상당한 영향을 끼친다. 이러한 영향을 장해석기(HFSS)에 적용할 수 있는 변수로 변환하여 보다 정확하게 시그널 인테그러티를 검증 할 수 있도록 한다. 단일 신호선과 두 개의 전자기적으로 결합된 신호선에서의 신호 천이 특성을 측정 데이터와 제안하는 방법의 시뮬레이션 결과와 비교를 통해 제안한 방법의 정확성을 검증하였다.
