- The following coverage strategy is implemented:
- * The counters are covered at the max
- and min corner cases and for the middle values
- * Data bus has functional coverage using walking ones and zeroes
- * One bit width variables are wrapped in one cover point
- while counters and data have designated cover points
- * Channel enable signal is stand alone cover point
+ Covers the ch0 pattern generation complete interrupt and event done.
+ Covers the ch1 pattern generation complete interrupt and event done.
