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.)

说明：  开发规范要求，严格按照此文档来进行编码，非常好的开发规范文档(Development specification requirements, strictly in accordance with this document for coding, very good development specification document)

说明：  1. 定义了刀具和工件结点的接触，并定义为默认“硬接触” 2. 工件上表面定义了自接触，防止切屑穿透工件上表面 3. 有些情况下可能产生工件右边界的部分结点卷曲后进入上表面，可以额外定义工件上表面与右边界部分结点（在右边界上，但是被切下来的部分结点）的接触算法这样就不会穿透了。(1. Defined the contact between tool and workpiece node, and defined as the default "hard contact". 2. Self-contact is defined on the upper surface of the workpiece to prevent the chip from penetrating the upper surface of the workpiece 3. In some cases, part nodes of the right boundary of the workpiece may curl into the upper surface, and the contact algorithm between the upper surface of the workpiece and the right boundary part node (the part node on the right boundary, but the part node cut off) can be defined in addition, so as not to penetrate.)
