IMA Hot Topics Workshop
Algorithmic Methods for Semiconductor Circuitry
November 24-25, 1997


Jacob White, MIT

The aim of the workshop was to bring together researchers who work on algorithmic methods together with researchers in semiconductor circuitry in order to address the difficult computational issues that arise in circuitry. The activities included informal presentations and discussions.


  • Linear and nonlinear model-order reduction (including eigenvalue-calculation based approach).

  • Methods for quasiperiodic analysis (including nonlinear phenomena in oscillating circuits: stability and bifurcation).

  • Fast PDE solvers plus MOR

  • Partitioning methods covering areas such as waveform relaxation, domain decomposition (parallel circuit simulation) and mixed level simulation.
