The AIE-ML array has a
single clock domain for all the tiles and array interface blocks. The performance
target of the AIE-ML array for the -1L
speed grade devices is 1 GHz with VCCINT at 0.70V. In
addition, the AIE-ML array has clocks for
interfacing to other blocks. The following table summarizes the various clocks in
the AIE-ML array and their performance
targets. For more information, see

Clock | Target for -1L | Source | Relation to AIE-ML Clock |
---|---|---|---|
AIE-ML array clock | 1 GHz | AIE-ML PLL | N/A |
NoC clock | 960 MHz | NoC clocking | Asynchronous, clock domain crossing (CDC) within the NoC |
PL clocks | 500 MHz | PL clocking | Asynchronous, CDC within AIE-ML array interface |
NPI clock | 300 MHz | NPI clocking | Asynchronous |
