Abstract
Circuit simulation packages generate the network equations automatically. In time domain analysis this results in a system of differential-algebraic equations that is solved numerically by BDF schemes and/or the trapezoidal rule. CHORAL, a charge-oriented Rosenbrock-Wanner method, has been developed as an alternative approach for digital circuits. By its successful implementation into TITAN, the circuit simulator of Infineon Technologies, a second integration scheme is available for the first time. Results for benchmarks and industrial circuits show that CHORAL is competitive with the standard ansatz and possesses advantages for oscillatory circuits.
Markus Hoschek expresses his sincere thanks to Siemens AG for awarding him a Ph.D. grant.
