Timing Characteristics
VersaTile Specifications as a Sequential Module
The ProASIC3 library offers a wide variety of sequential cells, including flip-flops and latches. Each
has a data input and optional enable, clear, or preset. In this section, timing characteristics are
presented for a representative sample from the library. For more details, refer to the Fusion,
