Math Functions
The ABM math function parts are shown in Table 6-2. 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 A/D “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.
ABM Expression Parts
The expression parts are shown in Table 6-3. These parts can be
customized to perform a variety of functions depending on your
Table 6-2
