any rough idea on the computational complexity (simulation speed) of Hspice or Spectre? I only know it is strongly dependent on the number of internal nodes of the circuit because Spice have to make matrix of it. is this dependency linear or exponetial, etc?

Hspice use gausian method to get the solution of a matrix, so the dependency will be exponential
Spectre may be a different, it may divide the circuits and some them simultaneously, the dependency is between linear and exponential

thanks for the reply. do u know where I can find some information about such things? books, papers, etc
