dds_test
说明： 直接数字式频率合成器DDS设计、Verilog。
产生的信号可以是正弦波或方波、三角波、锯齿波等，自选。
采用DDS技术，将所需生成的波形写入ROM中，按照相位累加原理合成任意波形。
此方案得到的波形稳定，精度高，产生波形频率范围大，容易产生高频。
本实验在设计的模块中，包含以下功能：
（1）通过 freq 信号输入需要的频率的值；
（2）通过 wave_sel 信号选择所需的波形；
（3）通过 amp_adj 信号选择波形放大的倍数。(DDS design of direct digital frequency synthesizer, Verilog.
The generated signal can be sinusoidal or square wave, triangular wave, sawtooth wave and so on, optional.
By using DDS technology, the required waveforms are written into ROM, and arbitrary waveforms are synthesized according to the principle of phase accumulation.
The waveform obtained by this scheme is stable, accurate and easy to generate high frequency waveform.
This experiment includes the following functions in the designed module:
(1) Input the required frequency value through freq signal;
(2) Choosing the required waveform by wave_sel signal;
(3) Select the multiplier of waveform amplification by amp_adj signal.)

本设计是针对LEON3 Altera Nios II startix2
This leon3 design is tailored to the Altera NiosII Startix2
Development board, with 16-bit DDR SDRAM and 2 Mbyte of SSRAM.
As of this time, the DDR interface only works up to 120 MHz.
At 130, DDR data can be read but not written.
NOTE: the test bench cannot be simulated with DDR enabled
because the Altera pads do not have the correct delay models.
* How to program the flash prom with a FPGA programming file
1. Create a hex file of the programming file with Quartus.
2. Convert it to srecord and adjust the load address:
objcopy --adjust-vma=0x800000 output_file.hexout -O srec fpga.srec
3. Program the flash memory using grmon:
flash erase 0x800000 0xb00000
flash load fpga.srec-This leon3 design is tailored to the Altera NiosII Startix2

EDA设计 交通灯
设计一个控制十字路口的交通信号灯。
某大学决定在校园学术路文化路交汇处安装交通灯，以控制交通。两套交通信号灯，redA，yellowA，greenA和redC，yellowC，greenC分别安装在学术路上和文化路上。两个传感器TA和TC分别安装在这两条路上。如果有交通，每个传感器都会显示为TRUE，如果街道为空，则表示FALSE。
当控制器复位时，学术路的绿灯亮，文化路上为红灯亮。
每5秒钟，控制器检查流量传感器并决定下一个状态。只要学术大楼出现交通，即TA=1，绿灯亮；当学术大街上无交通， 黄灯亮5秒钟，然后变成红灯，同时文化路上绿灯亮。
在这种状态下，每5秒控制器检查文化路上的交通传感器。只要文化路上有交通就保持绿灯亮。如果没有交通，绿灯会变成黄灯，最后变成红灯。
