System ACE SC
The SMT498 FPGA PMC module is equipped with In System FPGA configuration
solution called System ACE SC. As soon as the board is powered up the FPGA is
configured from the flash. The System ACE SC has a PROM, Configuration
controller, and a Flash. For more information on System ACE look at:
System ACE
PROM
The System ACE SC solution has a OTP PROM XC17V01. The PROM is
programmed with the configuration controller before it is installed on the board.
Configuration Controller
The XCV50E is used as the configuration controller. The PROM on power up
configures the Virtex-E chip (XCV50E). After configuration the XCV50E is seen as a
XCCACE64M (System ACE chip) in the JTAG chain. The controller forms a link
between the Flash and the target FPGA. Four status LEDs are connected to the
controller to monitor its state. (See the Appendix for status bit encoding table).
Flash
A 8MB Flash ROM device is connected to the XCV50E configuration controller. The
target FPGA bitstream is loaded in to this Flash via JTAG to configure the FPGA on
power up.
