Difficulty: Easy
Correct Answer: Correct
Explanation:
Introduction / Context:
HDLs such as VHDL and Verilog allow two main styles of design: behavioral (describing what the circuit does) and structural (instantiating components and wiring them together). Students often wonder whether the act of connecting components is difficult or error-prone.
Given Data / Assumptions:
Concept / Approach:
Structural HDL is akin to drawing a schematic with text. Once component interfaces (entity/module ports) are known, interconnection is straightforward: declare signals, instantiate components, and map ports to signals. Good naming and consistent types make the task routine rather than difficult.
Step-by-Step Solution:
Verification / Alternative check:
Typical introductory HDL labs include building adders, multiplexers, and small datapaths structurally. Students reliably wire components with minimal difficulty when they use named associations and maintain type consistency.
Why Other Options Are Wrong:
Difficulty is not dictated by simulator brand. Structural connections are absolutely valid for synthesizable RTL; testbenches are not the only context. Declaring that it is “Incorrect” ignores common practice in industry and academia.
Common Pitfalls:
Mismatched bus widths, mixing std_logic with std_logic_vector inconsistently, or relying on positional port mapping which can lead to miswiring if the port order changes.
Final Answer:
Correct
