Which of the following is the correct way to define a guard trace in a PCB layout tool?
ADraw a trace overlapping the sensitive signal and assign it to the signal net
BDraw a trace around the sensitive signal and assign it to the power net
CDraw a trace around the sensitive signal and assign it to the ground net
DDraw a trace disconnected from any net around the signal
Step-by-Step Solution
Solution:
  1. Step 1: Understand guard trace assignment

    Guard traces must be connected to ground to shield signals effectively.
  2. Step 2: Check trace placement and net assignment

    Drawing around the signal and assigning to ground is correct; power or floating is wrong.
  3. Final Answer:

    Draw a trace around the sensitive signal and assign it to the ground net -> Option C
  4. Quick Check:

    Guard trace = ground net trace around signal [OK]
Quick Trick: Guard trace must be grounded and surround the signal trace [OK]
Common Mistakes:
MISTAKES
  • Assigning guard trace to power net
  • Overlapping guard trace on signal trace
  • Leaving guard trace unconnected
