For instance, consider the following example, where an HDL code produces a simplistic digital circuit design. module HalfAdder ( input A, // First input bit input B, // Second input bit output Sum, // Sum output output Cout // Carry output ); assign Sum = A ^ B; // XOR operation...

Now that we have defined a hierarchy, we can reference any named Verilog object or hierarchical name reference, by concatenating the names of the modules, module instance names, generate blocks, tasks, functions, or named blocks that contain it. Each of the names in the hierarchy is separated...
(2) items that are defined inside of a package are not permitted to makehierarchical referencesto items outside of that package. (this is also why we needvirtual interface) Another thing is that wildcard import statement import pkg::*; doesn't import any identifiers (just make them candidate...
The quickest way to verify the parameter values is to compile (build) the design, then navigate through the resulting graphical design hierarchy tree which shows the computed values of the parameters for each IP instance. You can search for all instances of a module in a tree by entering the...
