Iterated Timing Analysis
In the previous two chapters, the circuit simulation problem was identified and efficient techniques to solve the problem were described. In this chapter, a detailed description of event-driven electrical simulation based on nonlinear relaxation methods is provided. The chapter begins with the equation flow for nonlinear relaxation when applied to the circuit simulation problem. Then the timing analysis and iterated timing analysis (ITA) algorithms are described. Algorithms for event-driven electrical simulation with block partitioning and global variable time-step control are presented in the next two sections. Finally, the issues relating to latency detection and event scheduling in ITA are discussed.
