ABSTRACT:
Improvements are made to an electronic circuit simulator. The circuit is represented by a set of nodes to which devices and components are connected. In a computer simulator of circuit behavior using the Harmonic Balancing methodology it is desirable to precondition the Jacobian matrix associated with the circuit equations. Proper preconditioning of the Jacobian matrix may increase the computational efficiency of the simulator. A preconditioning matrix for the Jacobian matrix may be obtained by generating an inverse matrix for dissimilar diagonal blocks.
