Waveform relaxation approach to PWL simulation of analogue andmixed A/D networks at the functional level

摘要

The application of waveform relaxation to the piecewise linearn(PWL) macro-simulation technique is considered. It is oriented towardsnfunctional-level analogue and mixed-signal structures of A/D networks.nThe main issues in the actual PWL approach are briefly described. Thenwaveform relaxation-based PWL algorithm is formulated in terms of anmathematical network model, and the convergence proof for it is given.nDifferent feedback loops faced in analogue and mixed A/D networks arendiscussed with respect to the algorithm convergence. Macro-simulationnexamples of practical use illustrating the presented approach are alsonincluded
