Timing Characteristics
VersaTile Specifications as a Sequential Module
The ProASIC3E 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, IGLOO/e, and ProASIC3/E
