In the fields of design on the electronic circuit of the hardware, the FPGA(Field Programmable Gate Array )has already been used by the most of electronic engineers, Modern EDA design tool (for example: ProtelDXP, Max + PlusⅡ,etc.), we can use the principle picture to design logic electronic circuit, and we also can use the function of hardware describe language to design the function that we need. Among them, VHDL language has been already very popular and essential in the electronic system design, it gets and becomes the main hardware and describe language, it also gets to be very suitable for design of the programmable logic device.
The subject of my graduation project is that“digital correlator is realized with FPGA”. It mainly examines my information theory and concept in logic design of digital correlator,match,and register zone.It tests my VHDL programmable ability of designing circuit by myself and so on. Observe and analyze design circuit ability, and actual programming ability independently.
The design tool adopted and similator environment is Max + PlusⅡ 10.2 of ALTERA Company, which can give us full effect to advantage of principle design picture and hardware describe language. Finally adopting the two methods of module to build up and write with VHDL language to realize the circuit of this correlator.
