Figure 2-22. INDDRXB Primitive
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 sysIO buffers. The block contains a register for SDR operation that is combined with an additional latch for
DDR operation. Figure 2-23 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 as a D-
type or as a 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 2-24 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.
