HDL organization (VHDL context): “Constants must be included in a package.” Evaluate this statement about design organization.

Introduction / Context:
Hardware description languages (e.g., VHDL) allow constants to be declared in various scopes. Packages are a recommended place to share constants across design units, but they are not the only legal place to define them.

Given Data / Assumptions:

• Context is VHDL-style packaging of shared declarations.
• Claim uses the word “must.”

Concept / Approach:
In VHDL, constants can be declared inside an architecture, a package, or other declarative regions depending on desired visibility and reuse. Placing widely reused constants in a package improves modularity, but it is not mandatory. Therefore the statement, as written, is incorrect.

Step-by-Step Solution:

Verification / Alternative check:
Synthesis and simulation tools accept constants declared locally in architectures or entities. Packages simply expose them project-wide.

Why Other Options Are Wrong:

Common Pitfalls:
Confusing best practice (“should”) with language requirement (“must”).

Final Answer:
Incorrect
