| 12 | +description: | |
| 13 | + This clock is quite much similar to the basic gate-clock[1], however, |
| 14 | + it supports a number of additional features, including |
| 15 | + companion clock finding (match corresponding functional gate |
| 16 | + clock) and hardware autoidle enable / disable. |
