Signal Transient and Crosstalk Model of Capacitively and Inductively Coupled VLSI Interconnect Lines
نویسنده
چکیده
Analytical compact form models for the signal transients and crosstalk noise of inductive-effectprominent multi-coupled RLC lines are developed. Capacitive and inductive coupling effects are investigated and formulated in terms of the equivalent transmission line model and transmission line parameters for fundamental modes. The signal transients and crosstalk noise expressions of two coupled lines are derived by using a wave-form approximation technique. It is shown that the models have excellent agreement with SPICE simulation.

Comprehensive Evaluation of Crosstalk and Delay Profiles in VLSI Interconnect Structures with Partially Coupled Lines
In this paper, we present a methodology to explore and evaluate the crosstalk noise and the profile of its variations, and the delay of interconnects through investigation of two groups of interconnect structures in nano scale VLSI circuits. The interconnect structures in the first group are considered to be partially coupled identical lines. In this case, by choosing proper values for differen...
متن کاملSpice Compatible Model for Multiple Coupled Nonuniform Transmission Lines Application in Transient Analysis of VLSI Circuits
An SPICE compatible model for multiple coupled nonuniform lossless transmission lines (TL's) is presented. The method of the modeling is based on the steplines approximation of the nonuniform TLs and quasi-TEM assumptions. Using steplines approximation the system of coupled nonuniform TLs is subdivided into arbitrary large number of coupled uniform lines (steplines) with different characteristi...
متن کاملEffect of Equal and Mismatched Signal Transition Time on Power Dissipation in Global Vlsi Interconnects
High density chips have introduced problems like crosstalk noise and power dissipation. The mismatching in transition time of the inputs occurs because different lengths of interconnects lead to different parasitic values. This paper presents the analysis of the effect of equal and unequal (mismatched) transition time of inputs on power dissipation in coupled interconnects. Further, the effect ...
متن کاملClosed-Form Expressions for Crosstalk Noise and Worst-Case Delay on Capacitively Coupled Distributed RC Lines
Closed-form expressions for a crosstalk noise amplitude and worst-case delay in capacitively coupled two-line and three-line systems are derived assuming bus lines and other signal lines in a VLSI. Two modes are studied; a case that adjacent lines are driven from the same direction, and the other case that adjacent lines are driven from the opposite direction. Beside, a junction capacitance of ...
متن کاملGeneralized traveling-wave-based waveform approximation technique for the efficient signal integrity verification of multicoupled transmission line system
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 t...
