Relaxation-based algorithms are efficient in simulating large-scale circuits. One of the Relaxation-based algorithms, ITA (Iterated Timing Analysis), has even been widely used in industry. Hence we present accelerating techniques to fasten ITA’s speed. The basic idea is to let ITA utilize local time steps of subcircuits as much as possible. Our techniques include a heuristic approach, a method based on Strength of Signal Flow, and the method combining the previous two techniques. Proposed methods are quite advantageous, which have been justified by real experiments.

This paper considers utilizing the popular ITA (Iterated Timing Analysis) algorithm in CSM (Combining Simulation Method) to do parallel large-scale circuit simulation. An automatic partitioning method for jobs of CSM is presented, in which the related load balancing issue is also discussed. All proposed methods have been implemented and tested. Experimental results justify pleasing effects of proposed methods.

In this paper, we propose a modified Waveform Relaxation algorithm to perform large-scale circuit simulation for MOSFET circuits containing lossy coupled transmission lines that have been encountered in modern circuit design community, in which a full time-domain transmission line calculation algorithm based on the Method of Characteristic is adopted. New software techniques are proposed to enhance the robustness as well as efficiency of the simulation process. All proposed methods have been implemented and executed to justify the claimed advantages.

This paper investigates incremental circuit/sensitivity simulations for large-scale MOSFET circuits using the well-known ITA (Iterated Timing Analysis) algorithm. Incremental simulation uses the result waveforms of previous simulation to fasten the simulation speed, which is quite advantageous in the practical incremental-modifying circuit design strategy. Most proposed methods have been implemented and tested to justify their advantages.
