支持数字元件仿真的SPICE插件，可以单独编译，里面有几个数字器件的模型，可以作为SPICE编程的参考。-Supporting components figure SPICE simulation plug-ins can be a separate compiler, which has some digital device model, SPICE programming can be used as reference.

xspice所支持的更为详细和全面的仿真电路示例程序，可以为写网表文件提供参考。-xspice supported by more detailed and comprehensive process simulation circuit example, we can write netlist file for reference.
