Interconnect

Definition

Interconnect refers to the system of pathways and connections that link various components within a digital design, facilitating communication and data transfer between them. This concept is crucial for ensuring that the different elements of an FPGA can work together seamlessly, allowing for efficient data processing and overall functionality of the device.
