Introduction / Context:
Large schematics can become unreadable if every wire is drawn end-to-end. An effective drafting convention is to break long or repetitive connections and use labels or reference designations to indicate continuity. The statement claims this practice is not acceptable; we must assess its validity.
Given Data / Assumptions:
- Schematic aims for clarity and maintenance utility.
- Net names, signal tags, or reference bubbles are available.
- Reader can cross-reference page and sheet numbers.
Concept / Approach:
Using interrupted paths with consistent net labels (e.g., +5V, GND, CLK_A) reduces visual clutter, minimizes crossovers, and improves comprehension. Industry standards and good practice encourage labeled nets, off-page connectors, and reference indicators for repeated or global signals.
Step-by-Step Solution:
Identify long or global connections that would create excessive crossings.Replace lengthy wires with labeled net stubs or off-page connectors.Provide sheet references (e.g., To Sheet 3, Net CLK_A) to maintain traceability.Ensure unique, unambiguous net names and a legend if needed.
Verification / Alternative check:
Have a reviewer trace a signal using only labels; if they can follow it reliably across pages, the simplification is successful.
Why Other Options Are Wrong:
Correct: The claim “not acceptable” is false; interrupted paths are widely accepted when labeled properly.Valid only for power rails / Allowed only on wiring diagrams: The technique is used for many nets on both schematics and interconnect diagrams.
Common Pitfalls:
Using inconsistent or duplicate net names.Omitting sheet references, causing ambiguity.
Final Answer:
Incorrect
