Explanation

What are the differences between blocking and non-blocking assignments in Verilog?

a: Blocking assignments occur simultaneously while non-blocking assignments occur sequentially. Explanation

Explanation

b: Blocking assignments are used in combinational logic, non-blocking in sequential logic. Explanation

Explanation

c: Blocking assignments force a specific sequence, non-blocking allow concurrent execution. Explanation

Explanation

d: Blocking assignments are used with numbers, non-blocking with strings. Explanation

Explanation

Explain the concept of 'race condition' in digital circuits and its relevance to Verilog design.

a: It represents a competition between different modules for resources in Verilog design. Explanation

Explanation

b: Race condition occurs when two operations depend on each other's output. Explanation

Explanation

c: It's a conflict situation in which the output depends on the sequence of operations. Explanation

Explanation

d: Race condition is a design error that is irrelevant in Verilog. Explanation
