//// ////
|
| 13 |
|
|
//// Make a rising-edge triggered flop with async reset with a ////
|
| 14 |
|
|
//// distinguished name so that it's output can be easily ////
|
| 15 |
|
|
//// traced, because it is used for asynchronous reset of some ////
|
| 16 |
|
|
//// flip-flops. ////
|
| 17 |
|
|
//// ////
|
| 18 |
|
|
//// This flop should be used instead of a regular flop for ALL ////
|
| 19 |
|
|
//// asynchronous-reset generator flops. ////
