4. Configuration Process and Flow
Before it is operational, the FPGA goes through a sequence of states, including initialization, configuration and wake-
up.
Figure 4.1 shows the configuration flow.
Figure 4.1. Configuration Flow
The CrossLink sysCONFIG ports provide industry standard communication protocols for programming and configuring
the FPGA. Each protocol provides a way to access the CrossLink device’s internal NVCM, or to load its configuration
SRAM.
The sysCONFIG ports capable of accessing the NVCM have a priority order. The MSPI configuration port does not have
the ability to alter the NVCM space, and as a result is not a factor in the sysCONFIG port priority scheme.
