MIG 7 Series v1.2 - Component switching limit error on PHY hard blocks due to incorrect timing model

描述

In ISE 13.2 software release, an error in the timing model for the PHASER and the PLL can causeincorrectcomponent switching limit errors on PHASER_OUT, PHASER_IN, OUT_FIFO, and IN_FIFOPHY hard blocks.

解决方案

These errors can be safely ignored.

The component limit switching errors only occur on -1 and -2L speed grades for Kintex-7 and Virtex-7 devices.Following are some examples of the physical resources that could possibly show the error:

This issue is scheduled to be fixed in MIG 7 Series v1.3 inISE software release 13.3.
