1.5.3. Latches

A latch is a small combinational loop that holds the value of a signal until a new value is assigned.
Synthesis tools can infer latches from HDL code when you did not intend to use a latch. If you do intend to infer a latch, it is important to infer it correctly to guarantee correct device operation.
Note: Design without the use of latches whenever possible.
