描述

Version Found: MIG 1.7

The MIG Series design sets a DQS_AUTO_RECAL parameter based on the configuration of the core.

This parameter is defined within the module user_design\rtl\phy\mig_7series_v1_7_ddr_byte_lane.v

This parameter is set correctly when using XST, but incorrectly with Synplify.

解决方案

To work around this issue, modify the setting of the DQS_AUTO_RECAL parameter within the user_design\rtl\phy\mig_7series_v1_7_ddr_byte_lane.v module as follows:

localparam   DQS_AUTO_RECAL = (BANK_TYPE == "HR_IO" || BANK_TYPE == "HRL_IO" || (BANK_TYPE == "HPL_IO" && TCK > 2500)) ? 1 : 0;

localparam   DQS_AUTO_RECAL = (BANK_TYPE == "HR_IO" || BANK_TYPE == "HRL_IO" || (BANK_TYPE == "HPL_IO" && TCK > 2500)) ? "1" :" 0";
