Sequential statements are used to express algorithms within processes and subprograms, where there is just one thread of control. Concurrent statements, on the other hand, express multi-threaded control. They are also used to represent structural decomposition of a design into concurrently operating subsystems.
In this chapter, we look at the enhancements to the statement repertoire in VHDL-2008. We start with changes to assignment statements, which include new sequential forms that mirror conditional and selected concurrent assignments. Next, we look at changes to case statements that allow matching of standard-logic ...
