本文使用实例描述了在 FPGA/CPLD 上使用 VHDL 进行分频器设 计,包括偶数分频、非 50%占空比和 50%占空比的奇数分频、半整数 (N+0.5)分频、小数分频、分数分频以及积分分频。所有实现均可 通过 Synplify Pro 或 FPGA 生产厂商的综合器进行综合,形成可使 用的电路,并在 ModelSim 上进行验证。 -This article describes the use of examples in the FPGA/CPLD prescaler to use VHDL to design, including the even-numbered sub-frequency, non-50 duty cycle and 50 duty cycle of the odd-numbered sub-frequency, semi-integer (N+ 0.5) sub-frequency, fractional-N, as well as scores of sub-band frequency points. All can realize through the Synplify Pro or FPGA manufacturers integrated synthesizer to form a circuit can be used and verified in the ModelSim on.

  • SPI
    design and implement a digital system on the Altera NIOS board which will read an analogue input using MicroChip’s SPI MCP3202 12-Bit A/D converter. The 8 most significant bits of the converted data will be displayed on two seven segments of the NIOS development board. The sampling frequency is 20kHZ. Use a potentiometer.(design and implement a digital system on the Altera NIOS board which will read an analogue input using MicroChip' s SPI MCP3202 12-Bit A/D converter.
