and are used to model and verify hardware behavior at a detailed level. The net data types also have multiple strength levels and resolution functions for multiple drivers of the net. SystemVerilog adds several new data types, which allow hardware to be modeled at...
Obviously, to produce a sine wave, you need access to thesinfunction. This is where DPI is handy to add the math functions to your simulation. Here is an example of apackageI created to contain the math functions: package math_pkg; //import dpi task C Name = SV function name import ...
(Qi66)What is "scope resolution operator"? (Qi67)What is the difference between Verilog Parameterized Macros and SystemVerilog Parameterized Macros? (Qi68)What is the difference between logic data_1; var logic data_2; wire logic data_3j; bit data_4; var bit data_5; (Qi69)What is the...
Class scope resolution operator :: Parameterized classes Objects A class defines a data type. An object is an instance of that class. An object is used by first declaring a variable of that class type (that holds an object handle) and then creating an object of that class (using the new...
