3.three. Item-Oriented Simulation
Object-Oriented Simulation (OOS) is usually a methodology that utilizes the principles of object-oriented programming (OOP) to product units. In OOS, the procedure is split into objects that represent real-earth entities. These objects have Homes (attributes) and behaviors (procedures), which connect with each other to simulate the program in general.
Application in PCB Design:
In PCB structure, OOS can be utilized to design complicated units that include a range of interconnected factors. One example is, OOS can simulate how components with a PCB interact with one another, accounting for aspects like sign hold off, interference, and ability usage.
