WebSystemVerilog typedef SystemVerilog typedef In complex testbenches some variable declarations might have a longer data-type specification or require to be used in multiple places in the testbench. In such cases we can use a typedef to give a user-defined name to an existing data type. WebJan 17, 2024 · SystemVerilog struct and union are handy constructs that can encapsulate data types and simplify your RTL code. They are most effective when the structure or union types can be used throughout a design, including as module ports, and with modules that support parameterized data types.
