modsim仿真必备，可以帮助你解决很多你对软件不熟悉的问题！-Simulation modsim necessary, I can help you solve many of the software you are not familiar with the problem!

一个简易的频率计，主要用检测在一定范围内的频率，当然频率过大会有误差(A simple frequency meter, mainly used for testing in a range of frequencies, of course, frequency of errors over the General Assembly)

4位ALU,有两个4位输入，4位输出实现逻辑运算和算术运算，逻辑与或非，加1，减1等等功能(4 ALU, logical and arithmetic operations)

shift register. vhdl verilog

设计一个能求出一个32bit字中两个相邻0之间最大间隙的电路。完成HDL设计及testbench描述，给出综合后的时序仿真结果。提交纸质文档。(Design a circuit that can find the maximum gap between two adjacent 0 in a 32bit word. The HDL design and testbench description are completed, and the result of comprehensive simulation is given. Submit paper documents.)

说明：  点亮led流水灯，通过调用锁相环，可以更改对应的时钟。(Lighting the LED pipelining lamp, the corresponding clock can be changed by calling the phase-locked loop.)

FPGA实现DSP的Verilog 示例(FPGA realization of DSP-Verilog Example)

一个模拟ISA界面的简易小程式，简单易懂-ISA interface, a simple simulation of a small program, easy-to-read

基于ISP的交通灯设计，实现了各路状态转换、警察控制、行人请求功能。(ISP traffic light design, to achieve the brightest state transitions, police control, pedestrian request feature.)
