SystemAce Configuration (Default Mode)
SystemAce is a Slave Serial configuration mode, and is the default mode for the QDR II
Demonstration Board.
If the SystemAce Controller (U2) detects a Compact Flash card present in socket P2, it
attempts to load a configuration file from the Compact Flash card into the FPGA.

1. Recommended SW5 switch setting for the SystemAce mode is 111; refer to
SelectMap Configuration
The Virtex-II FPGA is programmable using SelectMap, a parallel configuration mode. In
this mode, two possibilities of programming exist:
•
Master Mode: FPGA delivers the CCLK download clock
•
Slave Mode: FPGA must receive the CCLK clock from the external device
The demonstration board can be programmed in both modes using the SelectMap
connectors; P99 and P111. The FPGA on the demonstration board can be programmed in
slave mode using a MultiLINX cable, or in Master mode when an external device is
plugged into these connectors.
The SelectMap connector P99 carries FPGA bits [7:0]. When SelectMap is not used, the
SelectMap connector pins can also be used as normal I/O.
