LogiCORE IP Ethernet 1000BASE-X PCS/PMA or SGMII v11.1 - Error - Invalid Target Device when Running Virtex-7 Example Design in 13.2 and Later

Description

When the LogiCORE 1000BASE-X PCS/PMA or SGMII v11.1 is generated for Virtex-7, the example design UCFtargets an xc7v285tffg784-1 device.Because this device is no longer a valid part, the tools will error out if the example design implementation script is run in ISE Design Suite 13.2 software or later.

Solution

The example_design/<core_name>_example_design.ucf can be modified to target one of the Virtex-7 devices available in the latest software.For example, at the top of theUCF, the target part can be changed to:

CONFIG PART = xc7v585t-ffg1761-1;

When using the1000BASE-X or SGMII core, the target part listed above is the only change needed. However, it is recommended that the following location constraints be removed as well:

INST "receive_gmii_tx_clk" LOC = "BUFIO_X0Y3" ;
NET "gmii_tx_clk_bufio" TNM_NET = "TN_gmii_tx_clk_bufio" ;
TIMEGRP "TN_gmii_tx_clk_bufio" AREA_GROUP = "CLKAG_gmii_tx_clk_bufio" ;
AREA_GROUP "CLKAG_gmii_tx_clk_bufio" RANGE = CLOCKREGION_X0Y0;

INST "drive_tx_clk" LOC = "BUFR_X0Y2" ;
NET "gmii_tx_clk_bufr" TNM_NET = "TN_gmii_tx_clk_bufr" ;
TIMEGRP "TN_gmii_tx_clk_bufr" AREA_GROUP = "CLKAG_gmii_tx_clk_bufr" ;
AREA_GROUP "CLKAG_gmii_tx_clk_bufr" RANGE = CLOCKREGION_X0Y0
