Math functions
The ABM math function parts are shown in Table 1. For
each device, the corresponding template is shown,
indicating the order in which the inputs are processed, if
applicable.
Math function parts are based on the PSpice “E” device
type. Each provides one or more inputs, and a
mathematical function which is applied to the input. The
result is output on the output net.
