MIG v3.9-3.92 Spartan-6 MCB - Design fails on the SP601 board using CES silicon
描述
Issue Found: MIG v3.9
When using the MIG v3.9-3.92 design on an SP601 board, the design fails in hardware. This issue only occurs when targetting an SP601 board with CES silicon.
解决方案
This failure occurs due to a change in the MIG rtl to support Self Refresh with Suspend operation (reference (Xilinx Answer 42802) for more information). As Self Refresh is not used int he SP601 design, revert the change In the infrastructure.v/vhd file asfollows:
From BUFGCE U_BUFG_CLK1 ( .O (mcb_drp_clk), .I (mcb_drp_clk_bufg_in), .CE (locked) ); To BUFG U_BUFG_CLK1 ( .O (mcb_drp_clk), .I (mcb_drp_clk_bufg_in) );
