基于GTK-wave做的verilog　test bench语法解析器 解析vcd file. 俺自己写的-VCD (Value Change Dump) file is widely used in industry. A VCD file is an ASCII file, which contains header information, variable definitions and the value changes for specified variables, or

应用verilog.HDL编写的PWM波的生成程序-Generation of application of verilog.HDL to prepare PWM wave

用verilog实现8为计数器频率范围20-80kHz，根据DDS原理来一个时钟计数器记一下，n=n+1，根据公式fout=（fc÷x）÷2，fout=80 fc=320，所以n≥2时，再取反，又由公式 fout=(k.fc)÷2^n，k=50hz，fout=80khz，fc=320，所以数据的位宽n≥7。 设计要求两路方波信号的相位差在0-360゜可调，可以根据延时来实现。具体的-8 is realized with verilog counter frequency range 20-8

在ISE环境下，使用Verilog语言，编写三角波程序，运用ModelSim进行仿真。-In the ISE environment, use Verilog language, written in a triangular wave program, using ModelSim simulation.
