Performance improvement techniques
Advanced methods in circuit simulation

An analog simulator is used to characterize standard cells, to design more complex basic blocks and functionalities, and also to verify complete circuits and systems-on-a-chip. To improve productivity and enable analog simulator users to process ever larger and more complex circuits, simulator performance is a constant challenge for the teams in charge of their development.

For more details, please refer to [E 3 450], but we can briefly recall here that simulating a circuit always results in the solution of a system of nonlinear algebraic-differential equations using Kirchhoff's...
