Behavioral Parts
Behavioral parts allow you to define how a block of circuitry
should work without having to define each discrete component.

behavioral parts
These parts use analog
behavioral modeling (ABM) to define each part’s behavior as a
mathematical expression or lookup table. The MicroSim
libraries provide ABM parts that operate as math functions,
limiters, Chebyshev filters, integrators, differentiators, and
others that you can customize for specific expressions and
lookup tables. You can also create your own ABM parts.
Di

ital behavioral parts
These parts use special
behavioral primitives to define each part’s functional and timing
behavior. These primitives are:
Many of the digital parts provided in the MicroSim libraries are
modeled using these primitives. You can also create your own
digital behavioral parts using these primitives.
LOGICEXP to define logic expressions
PINDLY to define pin-to-pin delays
CONSTRAINT to define constraint checks
