Parameterized for Data Width
Choice of Input Buffers
Choice of Output Buffers (ProASIC3/E only)
Choice of Bidirectional buffers (ProASIC3/E only)
Axcelerator, ProASIC3/E, Fusion
SmartGen can generate Dual Data Rate Registers parameterized for a specific Data Width and with a choice of the type of Input Buffers.
In ProASIC3/E, the DDR Registers may also be combined with output buffers or bi-directional buffers.
The Bidirectional enable signal polarity (TriEN) is selectable.
