Flexibility

Definition

Flexibility refers to the ability of a design to adapt to changing requirements and constraints, allowing for modifications without extensive redesign. In digital design, especially in the context of FPGAs, flexibility is crucial as it enables engineers to implement a wide range of functionalities while easily accommodating future updates or adjustments. This adaptability is key to optimizing performance and resource usage within the design flow.
