- Definitions
-
- Equations You use this keyword to define the beginning of the
- equations segment in a PDS file.
-
- Boolean Assign equations that include an output pin or node
- Equations name, an assignment operator, and an expression.
- Equations can be standard Boolean, Case, or
- IF-THEN-ELSE constructs.
- ·
- Use
- The keyword EQUATIONS is required when Boolean equations follow.
-
- Note: PALASM software does allow both Boolean equations and
- state-machine descriptions in the same design file.
