Functional chaining mechanism allowing definable models of electronic devices

Fast and stable processing optimized for given simulation problem is essential for any modern simulator. It is characteristic for electronic circuit analysis that complexity of simulation is given by circuit size and used device models. Implementation of electronic device models in program SPICE uses traditional functional paradigm allowing fast computation but further modification of model can be questionable. In this article, we propose modification of standard procedure inserting functional computation layer into the process. It allows on-the-fly modification of standard models and own functional definition during circuit definition without a loss in computational performance. It also gives a possibility of functional chaining mechanism and improves mapping performance of circuit variables to device models.
