- 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 today’s 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 ( -coupled) transmission line system are decoupled into -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.
