Are Case Statements sequential?

Are Case Statements sequential?

Sequential VHDL code is executed line by line. A sequential circuit uses memory elements, such as registers, to store the internal state of the circuit. We can think of the “case” statement as the sequential equivalent of the “with/select” statement; however, the “case” statement is more general.
