Question 1

What is the function of an 'Output Job' file in Altium Designer?

Accepted Answer

It consolidates all fabrication outputs (Gerbers, drill files, BOM) into a single configurable job that can be run repeatedly

Answer

An Output Job file packages all required manufacturing outputs so the entire fab package can be regenerated consistently with one click.

Question 2

Which technology in modern EDA tools uses machine learning to suggest optimal component placement based on connectivity and thermal constraints?

Accepted Answer

AI-assisted placement

Answer

AI-assisted placement tools analyze net topology and thermal hotspots to recommend placement arrangements that reduce routing complexity.

Question 3

In PCB design software, what does 'cross-probing' between the schematic and layout editors allow a designer to do?

Accepted Answer

Click a component or net in one editor and have it automatically highlighted in the other editor

Answer

Cross-probing links the schematic and PCB editors so selecting an element in one view instantly highlights it in the other, speeding up debugging.

Question 4

What is the role of a 'design variant' feature in PCB EDA software?

Accepted Answer

It manages multiple versions of the same board that differ in component population without maintaining separate schematics

Answer

Design variants let you define which components are fitted or unfitted for different product configurations (e.g., standard vs. premium) within a single design file.

Question 5

Which PCB EDA capability lets designers simulate the thermal distribution across a board during operation without leaving the design environment?

Accepted Answer

Integrated thermal analysis / thermal simulation

Answer

Integrated thermal simulation tools compute steady-state or transient temperature maps based on component power dissipation and PCB thermal conductivity.
