ACTIVE LEAKAGE RESISTANCE CONTROL TO IMPROVE NUMERICAL CONVERGENCE IN AN ELECTRONIC CIRCUIT SIMULATOR WHICH SEEKS CIRCUIT SOLUTIONS ITERATIVELY

摘要

Operation of an electronic circuit simulator is improved by actively controlling the test leakage resistance values at junctions (12) of active devices while seeking stable circuit solutions of modeled circuitry. By choosing an initial junction leakage resistance value lower that the actual value in each active device being modeled, convergent circuit solutions can be easily obtained, which may in turn be used as initial conditions to achieve the circuit solution for the real circuit with a significantly improved effectiveness.
