Design Advisory - 7 Series Package Flight Time Changes in ISE 14.2 and Vivado 2012.2 Design Suite Releases

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

Action Required for New 7 Series Board Designs

  • Customers must use the new flight time data in the ISE 14.2 and Vivado 2012.2 design tools.

Action Required for Existing 7 Series Board Designs

  • Use the following table based on memory data rate and check if your device/package combination is listed:

Up to 1066 Mbps

1067 to 1333 Mbps

1334 to 1866 Mbps
