Chapter 9examines the enhancements to design hierarchy that SystemVerilog provides. Significant constructs are presented, including nested module declarations and simplified module instance declarations. Chapter 10discusses the powerful interface construct that SystemVerilog adds to Verilog. Interfaces greatly sim...
When placed at the beginning of a module, it only applies to that module and has no effect on later modules, or nested module instances. If you put a timeunit construct outside a module, it applies to all modules declared in that compilation unit. You can only have one ‘timeunit’ ...
A case statement is a select-one-of-many construct that is roughly equivalent to an if-else-if statement. The general case statement in Figure 26 is equivalent to the general if-else-if statement shown in Figure 27. case (case_expression) case_item1 : case_item_statement1; case_item2 ...

Dynamic data and code definition can't be mapped to logic hardware. Nested (recursive) definitions can be used in generate constructs, but they are translated to parallel logic at compile time. If the recursion count isn't limited somehow, the construct isn't synthesiz...
But such definition makes global clock very expensive • In SystemVerilog there is a special construct for global clocking definition May be declared anywhere in the design Default clocking defines the default clock for assertions module m(input logic clk, …); global clocking @(posedge clk); ...
