二极管的hspice模型代码

主要完成ADI公司的DAC（数字-模拟转换器）AD9747的SPI接口及寄存器配置(Mainly to complete ADI' s DAC (digital- analog converter) SPI interface to configure the AD9747 and the register of)

说明：  计算机组成原理实验多时钟周期CPU设计，包含VHDL代码的设计，实验电路图，实验详细截图。(Computer component experiments designed more CPU clock cycles, including VHDL code design, test circuit, test detailed screenshots.)

FPGA的驱动并行接口的DAC程序，效率较高。(FPGA-driven parallel interface of the DAC process more efficient.)

资源描述该代码通过采用Verilog语言中的for循环语句实现了格雷码转二进制代码的功能，不同于网上的代码是该代码进行了修正，通过了ModelSim仿真完全正确，可以用来作为for循环语句的学习

ahb总线的sram 控制器设计，支持8/16/32位传输，支持片选信号达到低功耗设计的目的。ahb增量传输和猝发传输二种方式。SRAM采用标准的SRAM产生器生成。自带mbist。代码经过验证。包含完整代码和验证环境

全自动洗衣机的控制器。 1.洗衣机的工作步骤为洗衣、漂洗和脱水三个过程，工作时间分别为：洗涤10秒，漂洗5秒，脱水5秒； 2.用一个按键实现洗衣程序的手动选择：A、单洗涤；B、单漂洗；C、单脱水；D、漂洗和脱水；E、洗涤、漂洗和脱水全过程； 3.用显示器件显示洗衣机的工作状态（洗衣、漂洗和脱水），并倒计时显示每个状态的工作时间，全部过程结束后，应提示使用者； 4.用一个按键实现暂停洗衣和继续洗衣的控制，暂停后继续洗衣应回到暂停之前保留的状态； (Automatic washing machine controller. 1 washing machine work steps for the laundry, rinsing and dehydration three processes, working hours are as follows: washed for 10 seconds, rinse for 5 seconds, dehydrated five seconds 2 with a button to manually select the program to achieve laundry: A, single-washing B, single rinse C, a single dehydration D, rinsing and dehydration E, washing, rinsing and dehydration the whole process 3 with a display device display the working status of washing machine (laundry, rinsing and dehydration), and each state countdown show working hours, after the whole process should prompt the user 4 laundry with a button to pause and continue control of laundry, laundry should be back after a pause pause before continuing to retain the state )

VIVADO 从此开始,详细讲解了vivado,FPGA开发工具的使用，对于初学者学习VIVADO工具很有用。(VIVADO from now on, explained in detail the use of vivado, FPGA development tools, for beginners to learn VIVADO tools very useful.)
