14.2 ChipScope IBERT - Virtex-7 - GTH - Wrong setting for QPLL_REFCLK_DIV

Description

When using IBERT for Virtex-7 GTH, QPLL_REFCLK_DIV is set incorrectly for QUAD 116 only.

With line rate=10.3125 and refclk =312.5M, it is set incorrectly to 1.

Solution

This parameter can be changed manually to '0' in the IBERT console.

This will be fixed in a future version of IBERT.
