This section briefly reviews the topics introduced in Section 4.1. There are three principal semantic styles for HDL coding: behavioral, register-transfer level (RTL), and structural cell-level netlist.
Behavioral-level models utilize the concurrent sequential process (CSP) paradigm for time-based model simulation. Behavioral models allow a sequential statement flow within an active process evaluation that assigns a new signal value on a subset of the possible execution paths; as a result, there is an inferred signal state that retains its value when not explicitly assigned. The RTL coding style explicitly defines all data registers and finite state machine elements, ...
