Choosing between circuit simulators and physical prototyping is not straightforward, as the suitability of each method may depend on the specific goals, requirements, and preferences of your project. Here are some general tips and guidelines to help you make an informed decision: Consider the complexity and scope of your project; the cost and availability of your resources; and the level and type of your skills and knowledge. For example, if your project involves simple or basic circuits, circuit simulators may be preferable as they can save time and resources, while providing accurate results. On the other hand, if your project involves complex or advanced circuits, physical prototyping may be preferable as it can give a realistic and reliable feedback. Furthermore, if you have a limited budget or access to components and equipment, circuit simulators may be more suitable in order to minimize material and energy consumption. In contrast, if you have sufficient budget or access to components and equipment, physical prototyping may be more suitable in order to use the latest or custom-made features or devices. Lastly, depending on your level of mathematical or software skills versus practical or hardware skills, you may prefer circuit simulators or physical prototyping respectively.
