... chip. 14.8 Summary In this chapter, we discussed the following aspects of logic synthesis with Verilog HDL: • Logic synthesis is the process of converting a high-level description of the design ... constraints is an important part of logic synthesis. High-level synthesis tools allow the designer to write designs at an algorithmic level. However, high-level synthesis is still an emerging ... states—s0 = 0 cents; s5 = 5 cents; s10 = 10 cents; s 15 = 15 cents The bubble diagram for the finite state machine is shown in Figure 14-10. Each arc in the FSM is labeled with a label <input>/<output>...

... LiB ] 14.3 Verilog HDL Synthesis For the purpose of logic synthesis, designs are currently written in an HDL at a register transfer level (RTL). The term RTL is used for an HDL description ... discuss RTL-based logic synthesis with Verilog HDL. Behavioral synthesis tools that convert a behavioral description into an RTL description are slowly evolving, but RTL-based synthesis is currently ... appear. If you rely on operator precedence, logic synthesis tools might produce an undesirable logic structure. Table 14-2. Verilog HDL Operators for Logic Synthesis Operator Type Operator Symbol...
