Logic

Definition

Logic is a formal system used to evaluate the truth of statements and arguments based on well-defined principles. It serves as the backbone of reasoning in both mathematical contexts and computer science, providing a framework for verifying correctness and establishing sound conclusions. In hardware design and verification, logic is crucial for ensuring that systems behave as intended, enabling accurate decision-making and facilitating error detection.
