Counter conditions can be used in two-way and three-way branching conditional statements. Each counter condition consumes one counter comparator.
Important: Each counter has only one counter comparator. This means that you can only use a particular counter in a counter condition once in the entire trigger state machine program.
The probe port conditions consist of a comparison operator and a value. The valid probe condition comparison operators are:
- == (equals)
- != (not equals)
Important: Each counter is always 16 bits wide.
Examples of valid counter condition values are:
- 16-bit binary value of 0
16'b0000_0000_0000_0000 16'b0000000000000000 - 16-bit hex value of 7A
16'h007A - 16-bit integer value of 123
16'u123
Examples of counter condition statements:
- Counter $counter0 equals binary 0
($counter0 == 16'b0000000000000000) - Counter $counter2 does not equal decimal 23
($counter2 != 16'u23)
