SHS2 Engineering · Semester 1 Week 20: Circuits and Machines

Lesson notes

Learning Objectives

Indicator: 2.2.1.LI.3 - Use CAD tools for the design and analysis of simple analogue electronic circuits. (Depth of Knowledge Level 3: Strategic Reasoning)

By the end of the lesson, learners can:

Identify the key features and functions of a CAD tool (specifically Proteus) for electronic circuit design and simulation.
Use the component selection and placement features of Proteus to construct a simple analogue circuit on the schematic editor.
Apply the simulation function of the CAD tool to run a virtual analysis of a basic analogue circuit and record output readings.
Compare the simulated performance of a circuit with its expected theoretical behaviour, identifying possible sources of discrepancy.
Demonstrate collaborative and communication skills by sharing design ideas and giving constructive feedback on peers’ simulated circuits.

Exemplars (from the NaCCA curriculum)

Experiential Learning: At the computer lab, the facilitator explains to learners how to use CAD tools (e.g., Proteus software) to design and analyse simple analogue circuits. The facilitator guides learners to design and simulate simple analogue circuits.
Problem-based and collaborative Learning: In groups, learners search online for basic analogue electronic circuits to simulate and analyse.
Problem-based, Collaborative and Experiential Learning: At the workshop, learners build and test the circuits they had simulated. Other groups observe and comment.

Assessment (2.2.1.AS.3). The document marks these depth-of-knowledge levels for this indicator: Level 3 Strategic reasoning.
