UG885 (v1.1) - VC707 Evaluation Board for the Virtex-7 FPGA User Guide - HA pairs listed twice for FMC connectors

Description

UG885 (v1.1), VC707 Evaluation Board for the Virtex-7 FPGA User Guide, lists the FMC HPC connector pinouts on pages 52 and 53.

For FMC1 HPC connector J35, the pins listed are:
34 LA pairs (LA00-LA33)
24 HA pairs (HA00-HA23)
22 HA pairs (HA00-HA21)

For FMC2 HPC connector J37, the pins listed are:
34 LA pairs (LA00-LA33)
24 HA pairs (HA00-HA23)
22 HA pairs (HA00-HA21)

Is this pin listing correct?

Solution

This pin listing is not correct, and lists the HA bus twice for each FMC header.
The correct pin listings should read:

For FMC1 HPC connector J35, the pins are:
34 LA pairs (LA00-LA33)
24 HA pairs (HA00-HA23)
22 HB pairs (HB00-HB21)

For FMC2 HPC connector J37, the pins are:
34 LA pairs (LA00-LA33)
24 HA pairs (HA00-HA23)
FMC2 header on VC707 does not support the HB bus

UG885 (v1.2) includes the correct pin listing.
