2022.1 English

You can use the same coding method as was shown to describe a clock enable to describe synchronous control logic, such as a synchronous reset or set.


IMPORTANT:   You cannot describe a sequential element with asynchronous control logic using a process without a sensitivity list. Only a process with a sensitivity list allows such functionality. Vivado synthesis does not allow the description of a Latch based on a wait statement. For greater flexibility, describe synchronous logic using a process with a sensitivity list.
