What is Verilog interview questions?

- What is the difference between blocking and non-blocking?
- Explain Verilog full case and parallel case.
- What is the difference between a task and a function?
- What is PLI?
- What is the difference between == and ===?
Why is it 2 b01 and 2 b10?
35) Why is it that “if (2’b01 & 2’b10)…” doesn’t run the true case? This is a popular coding error. You used the bit wise AND operator (&) where you meant to use the logical AND operator (&&).
What is Delta simulation time?
Delta Time is a simulation time cycle It is used to order sequential events during simulation. More than one event can occur during a delta time. ∎ The time between any two sequential events is called a delta. These two events may be happening at the same real time but.
How to write a Verilog code without a temp Reg?
1) Write a verilog code to swap contents of two registers with and without a temporary register? With temp reg ; always @ (posedge clock) begin temp=b; b=a; a=temp; end Without temp reg; always @ (posedge clock) begin a <= b; b <= a; end Click to view more

How to write Verilog code for digital designers?
A simple and common interview question for digital designers is to write Verilog code to generate Gray Code. I’ve seen two ways to accomplish this. The first method is converting the binary counter to Gray Code using a case statement. However, there is an easier method, a more general use method that you should be aware of also.
How to do a blocking assignment in Verilog?
1. Evaluate the RHS (right-hand side equation) and update the LHS (left-hand side expression) of the blocking assignment without interruption from any other Verilog statement. A blocking assignment “blocks” trailing assignments in the same always block from occurring until after the current assignment has been completed
