... Figure 7-1. FSM for Traffic Signal Controller Verilog description The traffic signal controller module can be designed with behavioral Verilog constructs, as shown in Example 7-37 . Example ... 7-36 . Notice how concise the behavioral counter description is compared to its dataflow counterpart. If we substitute the counter in place of the dataflow counter, the simulation results w...

... now relate these hierarchical modeling concepts to Verilog. Verilog provides the concept of a module. A module is the basic building block in Verilog. A module can be an element or a collection ... checking, and coverage. However, these languages do not replace Verilog HDL. They simply boost the productivity of the verification p rocess.

... Next, we write the Verilog description for T_FF (Example 6-7 ). Notice that instead of the not gate, a dataflow operator ~ negates the signal q, which is fed back. Example 6-7 Verilog Code for ... Negative Edge-Triggered D-flipflop with Clear Given the above diagrams, we write the corresponding Verilog, using dataflow statements in a top-down fashion. First we design the module co...

... by an interrupt ($stop).  Verilog is a concurrent programming language unlike the C programming language, which is sequential in nature. Activity flows in Verilog run in parallel rather ... grouping is not necessary. This is similar to the begin-end blocks in Pascal programming language or the { } grouping in the C programming language. Example 7-1 illustrates the use of...
