Engineers involved in product design and manufacturing use computer-aided design/computer-aided manufacturing (CAD/CAM) systems, which is an example of specialized information systems called knowledge work systems (KWSs) that create information in their areas of expertise.?

Engineers who are involved in product design and manufacture of computer-aided should have enough knowledge in circuit and auto cad electronic design.

Explanation:

He or she should have mother board, voltage in or out extra. Person who develops should enough knowledge on circuit design which capacitor, resistance and voltage and processor capacity.

Each design they have first simulates and tested and result should be recorded. On simulation test success design is made.

There is third party software also available for design the circuit and gives the tested results as report.
