NI sbRIO-9651 System on Module Carrier Board Design Guide
FPGA Config
The sbRIO-9651 SOM provides an FPGA Config signal to indicate when the FPGA is
configured.
FPGA Config Signal Definitions
Table 1-18 describes the FPGA Config pins and signals on the sbRIO-9651 SOM connector.
FPGA Config Implementation on the
Reference Carrier Board
Figure 1-9 shows a schematic design for the FPGA Config implementation on the reference
carrier board.
