Modules are fundamental building blocks for structural and behavioral system description in the Verilog-A language. Ports provide module connectivity and allow communication between a module and its environment. When working on large designs, it is a common practice to decompose a system into a set of interconnected modules representing system components. Verilog-A supports a hierarchical system design by allowing modules to be instantiated within other modules. Higher-level modules create instances of lower-level modules and communicate with them ...
