Early-late gate

WebThe early-late gate technique is used for the design of Bit Synchronizer. The digital system design is simulated in MATLAB and the VHDL code developed in ACTEL LIBERO software is simulated in ModelSim simulator. Finally, the whole system is implemented in ACTEL PROASIC3E FPGA. The major advantages of the system include reprogrammablility ...
