System ACE CompactFlash Solution
CompactFlash (CF) to Configuration JTAG (CFGJTAG) Setup
This setup provides a standard CompactFlash interface for high-density FPGA systems. The CompactFlash interface is the
source of configuration data. The data configures the Xilinx FPGA chain through Boundary-Scan (JTAG) using the
Configuration JTAG port, as shown in
The System ACE CF controller handles all necessary steps to perform configuration from the CF to the target system. The
appropriate signal connections for this setup are shown in
any of the other interfaces.
