As an experiment I generated a 208x208 mesh plane model. Just
to read it into Hspice (2001.2) without even doing any simulation
at all took 1398 seconds ( ~23 minutes) on a 440 MHz Ultra-10
workstation. Had this model been used for a simulation it would
have been able to simulate a board 10ft 3in square accurately to
1 GHz (or a much smaller board to a much higher frequency).
What's it prove? Not much except to point out that very large
models consume lots of computer resources, and that users need
to make intelligent choices on how detailed of a model makes
sense for any particular application......
