Xilinx suggests that you instantiate this in the testbench file and not an implementation file or file used during
synthesis of the design. It may be used in conjunction with the design in order to help determine interaction and
start-up sequences between configuration loading and device start-up. In general, a configuration bitstream file
is to be used in conjunction with this model in order to observe configuration behavior.
More information on simulating and using this component can be found in the Xilinx Synthesis and Simulation
Design Guide. Please refer to that guide for further detail on using this component.

Width Function
2 Mode pins - determine configuration mode.
1 Active-Low asynchronous full-chip reset.
1 Determines the direction of the D[x:0] data bus:
• 0 = inputs
• 1 = outputs
RDWR_B input can only be changed while CSI_B is deasserted,
otherwise an ABORT occurs
