Working Principles

The LC4256V-75T100I operates based on the principles of programmable logic. It consists of configurable logic blocks (CLBs), interconnect resources, and input/output blocks (IOBs). The CLBs contain look-up tables (LUTs) that can be programmed to implement desired logic functions. The interconnect resources allow for flexible routing of signals between different CLBs and IOBs. The IOBs provide interface connections for external signals.

During programming, the desired logic functions are defined using an HDL and then synthesized into a configuration bitstream. This bitstream is loaded into the PLD, configuring the internal circuitry to perform the specified logic operations.
