Hardware description languages — comment syntax claim Assess the statement: “The comments in ADHL are enclosed between # characters.” Determine whether this assertion about comment delimiters is correct.

Difficulty: Easy

Correct Answer: Incorrect

Explanation:


Introduction / Context:
Comment syntax varies across hardware description languages and vendor-specific dialects. Accurate knowledge of delimiters is important for toolchains to parse code correctly. This question checks a specific assertion about using the # character as a comment delimiter.


Given Data / Assumptions:

  • “ADHL” is presented as a hardware description language context.
  • We are to judge the correctness of the claim about comment markers.


Concept / Approach:
Common HDLs such as VHDL and many vendor dialects do not use # as a general comment delimiter. For example, VHDL uses double hyphen for line comments. Therefore, the blanket assertion that comments are enclosed between # characters is not a correct general rule for HDL usage.


Step-by-Step Solution:
Identify typical HDL comment conventions (e.g., line-based double hyphen in widely used dialects).Compare with the given claim using # … #.The discrepancy indicates the statement is incorrect in the standard HDL context.


Verification / Alternative check:
Consulting language references or tool documentation will confirm the expected delimiters for comments and that # is not the generic enclosure.


Why Other Options Are Wrong:
Qualifiers about block comments or simulation-only usage do not convert the base statement into a correct general rule.


Common Pitfalls:
Transferring comment syntax from scripting languages (which may use #) into HDL code, leading to parsing errors.


Final Answer:
Incorrect
