Output Register Block
The output register block provides the ability to register signals from the core of the device before they are passed
to the sysI/O buffers. The block contains a register for SDR operation that is combined with an additional latch for
DDR operation. Figure 2-29 shows the diagram of the Output Register Block.
In SDR mode, ONEG0 feeds one of the flip-flops that then feeds the output. The flip-flop can be configured a D-
type or latch. In DDR mode, ONEG0 is fed into one register on the positive edge of the clock and OPOS0 is
latched. A multiplexer running off the same clock selects the correct register for feeding to the output (D0).
Figure 2-30 shows the design tool DDR primitives. The SDR output register has reset and clock enable available.
The additional register for DDR operation does not have reset or clock enable available.
