LogikOptimierung

Logikoptimierung, also known as logic optimization, is the process of transforming a digital logic circuit into an equivalent circuit that has a reduced number of logic gates, fewer inputs to gates, or a shallower logic depth. The primary goal is to minimize the area occupied by the circuit on an integrated circuit (IC) chip, reduce power consumption, and potentially improve its speed.

This optimization is crucial in the design of very-large-scale integration (VLSI) circuits. Different optimization techniques exist, broadly categorized into two main types: combinational logic optimization and sequential logic optimization. Combinational logic optimization focuses on circuits where the output depends solely on the current inputs, while sequential logic optimization also considers the influence of past inputs stored in memory elements like flip-flops.

Common methods include Boolean algebra simplification, Karnaugh maps for smaller circuits, and more advanced algorithms for complex designs such as Quine-McCluskey and Espresso. These algorithms work by identifying and eliminating redundant logic, merging equivalent functions, and restructuring the circuit to achieve the desired optimizations. The trade-offs between area, power, and speed are often considered during the optimization process, as improving one aspect might negatively impact another. Logic optimization is typically performed by specialized Electronic Design Automation (EDA) tools.
