Design Advisory for 7 Series FPGA Transceivers - GTX Port Name Changes in ISE 13.2 Software

Description

ThisDesign Advisory covers the name changes forGT ports in the 7 Series FPGAs Transceiversmodels and wizard released with ISE 13.2 software.

Solution

Customers using the ISE13.1 software should be aware that the port list in 7 Series FPGAs Transceivers wizard v1.4 and model (released with ISE 13.2 software) has been modified, and users need to update their instantiations to account for these port changes.

Port Name Changes

GTXE2_CHANNEL module:

'CPLL_RXOUT_DIV' is changed to'RXOUT_DIV'
'CPLL_TXOUT_DIV' is changed to 'TXOUT_DIV'

These names are changed to reflect the fact that these output dividers in the channel can be used with either QPLL or CPLL. These names have been updatedin v1.2of the 7 Series FPGAs GTX/GTH Transceivers User Guide (UG476).

GTXE2_COMMON module:

'BGBYPASS' is changed to'BGBYPASSB'

'BGMONITOREN' is changed to 'BGMONITORENB'

For example, these ports in the GTXE2_COMMON moduledefined in the gtwizard_v1_x.v/vhd file are being changed as follows:

Change:
BGBYPASS=> tied_to_ground_i,
BGMONITOREN=> tied_to_ground_i,

To:
BGBYPASSB => tied_to_vcc_i,
BGMONITORENB=> tied_to_vcc_i,

These new port names will be used going forward starting from ISE 13.2 software.
