Chapter3: Board Component Descriptions
On first use of the SCUI, go to the FMC > Set VADJ > Boot-up tab and click USE FMC
EEPROM Voltage. The SCUI buttons are grayed out during command execution and return
to their original appearance when ready to accept a new command. See Figure 3-29.
See the VCU118 System Controller Tutorial (XTP447) and the VCU118 Software Install and
Board Setup Tutorial (XTP449) for more information on installing and using the System
Controller utility.
Configuration Options
[Figure 2-1, callout 35]
VCU118 boards earlier than Rev. 2.0 host a linear BPI 16-bit flash configuration memory,
1 Gb (U133) Micron MT28GU01GAAA1EGC-0SIT. See Appendix C, BPI Flash Memory for
VCU118 Boards Prior to Revision 2.0.
The VCU118 board supports two of the seven UltraScale FPGA configuration modes:
• Master SPI using the onboard dual Quad SPI flash memory
•JTAG using:
°
USB JTAG configuration port (Digilent module U115)
°
AMD platform cable 2 mm, keyed flat cable header (J3)
See UltraScale Architecture Configuration User Guide (UG570) [Ref 2] for further details on
configuration modes.
Each configuration interface corresponds to one or more configuration modes and bus
widths as listed in Table 3-35. The mode switches M2, M1, and M0 are on SW16 positions 2,
3, and 4, respectively. The FPGA default mode setting M[2:0] = 001, selecting the master SPI
configuration mode.
