The timing diagram in
I/O is an output switching to an input using 3-state control. The switching characteristics
shown in the diagram are specified in the Virtex-5 FPGA Data Sheet.
X-Ref Target - Figure 7-12
The activities of the OBUFT pin are controlled by the propagation and state of the
TSCONTROL signal from the ODDR flip-flop. The 3-state control data receipt on the
OBUF and IDDR flip-flop from a PAD are in parallel with each other, depending on the
IDELAY_VALUE setting the final value at the IDDR flip-flop input in response to a clock
edge is valid before or after the pad is driven from the 3-state control. After the 3-state
control propagates through to the PAD and the IODELAY has been switched to an input,
the IDDR setup time is the sole determiner of timing based on the IDELAY_VALUE and
other timing parameters defined in the Xilinx speed specification and represented in the
ISE tools.
