| 18 | | The WARP FPGA board also includes Xilinx's SystemACE !CompactFlash chip for managing the configuration process of the FPGA. The SystemACE chip acts as an interface between the FPGA and a standard !CompactFlash slot. The SystemACE automatically configures the FPGA on powerup or when the manual reset button is pushed. Multiple configuration files can be stored on the CF card. The SystemACE chip reads a 3-bit address from a DIP switch to choose one of eight configuration files. The fourth position on the DIP switch, labeled CFGMODE, should generally be set to 1 (slid to the right). |

| | 23 | Two LEDs indicate the status of the SystemACE controller. The green LED will glow when the controller has successfully configured the FPGA using a bitstream on the !CompactFlash card. The red LED will blink when no !CompactFlash card is installed; it will glow continuously if there was an error downloading a bitstream to the FPGA. These LEDs do not indicate the status of the FPGA's configuration if you are not using the SystemACE to configure the FPGA. |
