verilog编写，巧妙的通过计数方式完成了三角波的波形，可直接对da输出。(verilog written, cleverly accomplished by counting the triangular waveform can be output directly to da.)

EDA/VHDL数字频率计，可编程逻辑门阵列，EDA课程设计(EDA/VHDL digital frequency meter, programmable logic gate array, EDA curriculum design)

七段数码管显示的时钟程序VHDL代码 ISE编译环境(SEVEN seg VHDL ISE CLOCK)

说明：  本设计是基于FPGA的高速并行接口通信接口和协议设计，该设计使用的是8 位并行接口，通过配置FPGA的FIFO寄存器保证了在高速并行下的数据稳定性，在 最终的测试中，该协议能够稳定传输的速度为80Mbps。(This design is based on FPGA high-speed parallel interface communication interface and protocol design, the design uses 8 Bit parallel interface ensures the data stability under high-speed parallel by configuring the FIFO register of FPGA. In the final test, the protocol can stably transmit at 80 Mbps.)

带有电网电压反馈的单相PWM整流器反馈，输出的波形很好，适合初学者学习观摩(With power grid voltage feedback single-phase PWM rectifier feedback, the output waveform is very good, suitable for beginners learning view )
