我也是去了解过，但没有找到这方面的资料在这里面很多人大谈特谈SPICE仿真但是SPICE仿真库的元件必定还是有限的，像开关电源很多零部件都是没有的像这些人都是哪来的仿真元件呢？powersur；你有这方面的了解资料的途径吗？另外；感谢你的回复!

powersur;请给我看一下吧我需要自建PWMICPC817变压器等等一些元件请给点意见

下面这个是SPICE自带的仿真程序，我复印出来的555仿真模块：我实在是看不懂555内部电路哪有那么多电阻节点二极管节点什么的如果我需要自建CPU模块那不需上百万的电阻元件我想这也是不可能的请哪位在顶一下吧！*555MCE*SnglTimer(Macromodel)pkg:DIP81,2,3,4,5,6,7,8*Connections:*              Gnd*              |  Trig*              |  |  Out*              |  |  |  Reset*              |  |  |  |  Ctrl*              |  |  |  |  |  Thresh*              |  |  |  |  |  |  Dischg*              |  |  |  |  |  |  |  Vcc*              |  |  |  |  |  |  |  |.SUBCKT555    1  2  3  4  5  6  7  8EREF15181.5GSOURCE8382612.5E-3GSINK3126167E-3VD1827DC.8VD2281DC.85VREF301DC1.2C1291700E-15RREF2301100E3RREF151100E3ROUT31100KR161500E9R221500E9R38575E3R45975E3R59175E3R610111E3R713141E3R8812150E3R948500E9R1020191E3R1116171E3R12818150E3R13821150E3R1422231E3R15826150E3R1624251E3R1971500E9R2029261E6D1111DMODD21211DMODD31214DMODD4114DMODD51817DMODD6117DMODD71819DMODD8119DMODD92114DMODD102125DMODD11123DMODD121823DMODD132625DMODD14125DMOD1D15327DMODD16283DMODE1101651000E2131291000E316115121000E422115211000E524115181000E72014301000M172911MOSMOD.MODELMOSMODNMOS(LEVEL=1KP=1VTO=1RD=5).MODELDMODD(RS=1E-6).MODELDMOD1D(RS=1E-6IS=1E-9).ENDS555

这些资料真的不错很感谢你的提供SPICE的仿真元件怎么建立在SPEIC自带元件库里的元件必定是有限的，特别是没有PWMIC变压器等。可以提供这方面的资料吗？

没有人回个贴子呀我自己顶一下
