Sure, here's a common Verilog interview question: **Question:** Explain the difference between blocking and non-blocking assignments in Verilog. **Answer:** In Verilog, blocking assignments (`=`) are executed sequentially in the order they appear in the code. This means that the right-hand side (RHS) is evaluated immediately, and the assignment is performed right away. Non-blocking assignments (`<=`), on the other hand, are used for modeling concurrent behavior. They allow multiple assignments to happen at the same time, without being influenced by the order in which they appear in the code. The RHS is evaluated immediately, but the assignment is scheduled to occur after all other statements in the current time step have been evaluated. This distinction is crucial for modeling digital circuits accurately, and using the appropriate assignment type depends on the intended behavior of the design.
