Abstract
As very large scale integration (VLSI) circuit speed rapidly increases, the inductive effects of interconnect lines strongly impact the signal integrity of a circuit. Since these inductive effects make the signal integrity problems much more serious as well as intricate, they become one of the critical issues in todays high-speed/high-density VLSI circuit design. In this paper, a generalized traveling-wave-based waveform approximation (TWA# technique is presented which can be accurately as well as efficiently employed for the signal integrity verification of the inductively dominated #moderate Q# multicoupled RLC transmission line system. The technique is composed of three steps. First, the signals in the multicoupled #n-coupled# transmission line system are decoupled into n-isolated eigen-modes #i.e., basis vectors). Next, the slow-transient low-frequency characteristics of the system response are determined, approximately, in the frequency-domain by using the dominant poles of the basis vectors. Finally, the fast-transient high-frequency characteristics of the system response are calculated in the time domain by using the traveling wave characteristics of the basis vectors. It is shown that the time-domain responses of the multicoupled RLC transmission line system can be accurately as well as efficiently modeled with the generalized TWA technique. Then, in inductance-dominant multicoupled interconnect networks, switching-dependent signal integrity, i.e., signal delay, crosstalk, ringing, and glitches are investigated extensively with the proposed technique.
