Common Mistakes

Confusing star with bus routing

Choosing mesh or ring which are different topologies

The star routing method connects all components to a single central point, like spokes on a wheel.

💡 Hint

Common Mistakes

Mixing bus with star routing

Selecting ring or mesh which are not typical power routing methods

Bus routing uses a common line shared by all components for power distribution.

Fix the error in the statement describing star routing: 'In star routing, all components connect along a {{BLANK_1}} line.'

PCB Design

description = 'In star routing, all components connect along a [1] line.'

💡 Hint

Common Mistakes

Choosing bus which describes bus routing

Selecting ring or mesh which are unrelated here

Star routing connects components to a central point, not along a bus line.

4fill in blank

hard

Fill both blanks to complete the comparison: 'Star routing reduces {{BLANK_1}} but requires more {{BLANK_2}}.'

PCB Design

comparison = 'Star routing reduces [1] but requires more [2].'

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up noise and cost

Confusing wiring with components

Star routing reduces noise by isolating branches but needs more wiring to connect each component to the center.

5fill in blank

hard

Fill all three blanks to complete the statement: 'Bus routing is {{BLANK_1}} to implement, but it can cause {{BLANK_2}} and {{BLANK_3}} issues.'

PCB Design

statement = 'Bus routing is [1] to implement, but it can cause [2] and [3] issues.'

💡 Hint

Common Mistakes

Choosing complex instead of simple

Mixing noise and cost or other unrelated issues

Bus routing is simple to implement but can cause noise and voltage drop problems due to shared lines.
