Hi all,
My customers use "DDR3_slave_ratio_search_auto.out", they all return with a value of 0, like the console below.
If PHY_INVERT_CLKOUT = 0, a value other than 0 is returned.
Does anyone know the reason why "DDR3_slave_ratio_search_auto.out" returns 0?

Enter the PHY_INVERT_CLKOUT value (0 or 1) from the spreadsheet

Enter the Seed RD_DQS_SLAVE_RATIO Value in Hex to search the RD DQS Ratio Window
40
Enter the Seed FIFO_WE_SLAVE_RATIO Value in Hex to search the RD DQS Gate Window
114
Enter the Seed WR_DQS_SLAVE_RATIO Write DQS Ratio Value in Hex to search the Write DQS Ratio Window
