Description

ISE 14.2 and Vivado 2012.2 design tools include NEW package flight times for all Kintex-7 and Virtex-7 device/package combinations. Package flight times are typically used in the matching of trace delays for Memory Interfaces and other high speed source synchronous interfaces.

NOTE: No packages have physically changed, but flight time (i.e., package trace delay) data is now more accurate due to an improved data extraction flow.

Solution
