Kintex-7 FPGA KC705 - UCF File Comparison between Rev B and Rev C

描述

SomeUCF file differences exist between Rev B and Rev C of the Kintex-7 FPGA KC705 Evaluation Kit. The pinout differences are listed in the table below.

Points to Note:

1. KC705 Rev C supports External VREF on the DDR3 Banks and the pin changes below are the result of implementing External VREF.

2. KC705 Rev C DDR3 Memory designs will require the following syntax in their UCF file: CONFIG DCI_CASCADE = "33 32 34";

3. Net PMBUS_CTL_LS has been removed on KC705 Rev C as it is no longer necessary
