The SelectIO™ Link Detect FSM with deskew operation ensures that the AXI Chip2Chip Master core initiates transactions only when both Master and Slave cores are out of reset and deskew patterns are exchanged without any bit errors. Deskew operations align data until an optimized sampling point is determined for the data. The nibble level deskew operation also enhances the maximum frequency of operation for the SelectIO interface.
