如果有了一个器件的Spice模型文件,如何才能知道它和符号管脚的对应关系呢?比如下面是在官网下载的TS393的Spice模型文件,文件前面写的是: l, z; n1 D9 i$ Q

2 e! U. k, w: z- o* M2 ^4 i& S$ y0 j: t, f
但是后面的内容没有3、4、5脚,却是这样写的:. U( J) r, k5 k% D1 k( D0 n1 |# @
.SUBCKT TS393 2 1 44 55 33
! r' x# ?# k9 B1 a( B* Z% f5 b, c0 t8 v' h
把这个模型导入仿真软件时,显示的管脚号也是2、1、 44、55、33,那么问题来了,这些管脚号和这个比较器的NON-INVERTING INPUT(同相端)、INVERTING INPUT(反相端)、POSITIVE POWER SUPPLY(电源正端)、NEGATIVE POWER SUPPLY(电源负端)、OUTPUT(输出端)是如何对应的呢?这里有什么规则吗?6 p$ t- r: i$ t
