Abstract
A new formal model for variable-delay simulators is presented for comparing the effects of time base on circuit parallelism. This model more accurately reflects current simulation strategies than previous models. Using this new model the author shows that parallelism is not a nondecreasing function of time base. She bounds parallelism, however, by two functions that converge to the unit-delay parallelism as the time base increases, preserving the intuition that coarser timing models result in greater parallelism. In addition, the author corroborates the model predictions via an empirical study and discusses the impact of the results on synchronous and conservative asynchronous parallel simulations.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
