... 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. Verilog HDL is still needed to describe the...

... Continuous Assignment Instead of declaring a net and then writing a continuous assignment on the net, Verilog provides a shortcut by which a continuous assignment can be placed on a net when it is ... to a high 10 time units later (time = 30). 2. When in1 goes low at 60, out changes to low at 70 . 3. However, in1 changes to high at 80, but it goes down to low before 10 time units hav...
