An extension to the popular SPICE circuit simulator is described that analyses analog circuits with digital com- ponents represented at the gate, functional or behavioral levels. The analog-to-digital conversion is performed by (multilevel) “thresholders” which assign digital signals to subranges of voltages determined by a set of voltage thresholds. The digital-to-analog conversion is implemented by voltage sources with “controlled” characteristics that approximate (discrete) digital signals by continuous piecewise linear functions. The paper outlines internal organization of mixed, analog/digital simulation, presents modification of analyses and extensions to the input language needed for analog-digital interactions, and describes the specification of digital circuits.
