What is the main purpose of length matching in parallel buses on a PCB?

ATo reduce the overall size of the PCB

BTo increase the voltage of the signals

CTo ensure signals arrive simultaneously and prevent timing errors

DTo simplify the routing process

Step-by-Step Solution

Solution:

Step 1: Understand signal timing in parallel buses
Signals traveling different lengths arrive at different times, causing errors.
Step 2: Identify the role of length matching
Length matching makes all signals travel equal distances to arrive simultaneously.
Final Answer:
To ensure signals arrive simultaneously and prevent timing errors -> Option C
Quick Check:
Length matching = prevent timing errors [OK]

Quick Trick: Signals must arrive together to avoid errors [OK]
