LogiCORE Triple Rate SDI v1.0 Virtex-6 - What is the correct signal name for the txbufstatus1 connection in the Verilog triple_sdi_rxtx_top.v top-level module?

Description

What is the correct signal name for the txbufstatus1 connection in the Verilog triple_sdi_rxtx_top.v top-level module?

Solution

Note: The problem below affects Verilog only and does not affect the VHDL top-level module.

The Verilog version of the v_triple_sdi_1_0 core does not drive the GTX TXRESET_IN pin correctly when the GTX TX buffer under or overflows. 

This is caused by an error in connecting the GTX TXBUFSTATUS[1] bit to drive the GTX TXRESET_IN port in the triple_sdi_rxtx_top.v file.

When the v_triple_sdi_v1_0 core is generated, the file is located at: <ise_project_dir>\ipcore_dir\<core_name>\hdl\triple_sdi_rxtx_top.v


To work around this problem, you must modify the signal connected to the txbufstatus1 port of the v6gtx_sdi_control module from gtx_txbufstatus to gtx_txbufstatus1 as shown below.

(This is located on line 508 of the triple_sdi_rxtx_top.v file)


Original: 

.txbufstatus1       (gtx_txbufstatus),

Updated: 

.txbufstatus1       (gtx_txbufstatus1),
