Design of Display Interface Embedded in Grating Measurement Chip

An embedded LCD interface in a grating measurement chip is implemented based on Verilog HDL, which includes four modules in the circuit, MCU, CDU, I/O and a synchronous FIFO.SMG12864C chip is used as the LCD driver module.Verilog HDL is employed in the interface circuit describing the design, software Modelsim accomplishes the function simulation, and the circuit is synthesized by Synplify tool. After post-simulation and verification on the Xilinx VirtexII family device, the timing analysis indicates that the designed circuit meets the requirement of display interface. Besides, the circuit also possesses a good flexibility, meaning that it is easy to adapt to other LCD driver modules by simply modifying the timing constraints in MCU module.
