Write a small function to push 10 unique values from 0 to 50 into a queue.
function random();
bit [7:0] array[$];
for (int i = 0; i 10; i++) begin
int num;
std::randomize(num) with { num inside {[0:50]};
!(num inside {array};
};
array.push_back(num);
end
endfunction
In Verilog, conditional statements are used to control the flow of execution based on certain conditions. There are several types of conditional statements in Verilog listed below.
Conditional Operator
<variable> = <condition> ? <expression_1> : <expression_2>;
The conditional operator allows you to assign a value to a variable based on a condition. If the condition is true, expression_1 is assigned to the variable. Otherwise, expression_2 is assigned.
Static cast is a SystemVerilog feature that allows converting an expression from one data type to another at compile time.
Syntax
'(value or variable or expression)
Properties
Here are some of the properties of static cast in SystemVerilog:
SystemVerilog DPI (Direct Programming Interface) is a feature that allows users to interface between SystemVerilog and foreign programming languages such as C, C++, and SystemC.
DPI enables users to integrate their SystemVerilog designs with external components written in other languages, creating a more powerful and flexible design environment. It also provides an easy and efficient way to connect existing code, usually written in C/C++ without the knowledge and the overhead of PLI/VPI.
What is a SystemVerilog interface ?
SystemVerilog interfaces are a way to create structured hierarchical connections between modules and blocks in a design. They provide a way to bundle signals and functionality into reusable components, which can be easily instantiated and connected in a design.
- Modular design: Interfaces provide a modular approach to design, making it easier to create and reuse building blocks in a system.
- Encapsulation: They help in encapsulating the functionality and signals inside a module or block, making it easier to understand and maintain.
- Configurability: Interfaces can be parameterized, allowing for easy configurability and scalability.
