ABSTRACT:
A simulation system of an electronic circuit. The system comprises a memory, a processor, an interface circuit and data, address and control buses connecting these components. The memory has a first zone containing data for representing the simulated electronic circuit, a second zone containing instructions and a third calculating zone. The state of the electronic circuit is determined by the electrical potential in each node. The processor performs the instructions contained in the second memory zone. The processor is able to calculated the potential of all the nodes at a fixed time T.sub.n, 1.ltoreq.n.ltoreq.N by solving for each node an implicit equation relative to the potential of said node, the calculation being successively repeated for the times T.sub.1, T.sub.2 . . . T.sub.N.
