- Definitions
-
- Pn.T1 Identifies the pin or node associated with the dual
- toggle flip-flop. The name must be defined in an
- earlier pin or node statement in the declaration
- segment.
-
- Assignment Operator A symbol that defines a specific operation as
- interpreted by the software when processing
- design files.
-
- Expression Identifies the logic you define to determine when to
- set the T1 input on dual toggle flip-flops high. In
- the syntax example, when IN1 is true and IN2 is false,
- the T1 input in the dual toggle flip-flop associated
- with the pin or node Q1 is set high.
- ·
- Use
- You can place the .T1 equation anywhere in the equations segment.
- Observe the following rules.
-
- ■ You cannot have multiple equations for the same pin or node. If
- you do, the software reports an error during compilation and the
- process is halted.
-
- ■ You cannot use negative polarity on the left side of the
- equation. For example, /Q1.T1 is not allowed.
-
- ■ You can use GROUP, STRING, and VECTOR notation to define signals.
- This is an excellent way to assign a .T1 equation to several
- pins.
