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:$ v O a7 j0 }- w% t

* 5 OUTPUT( {( R, G5 x$ X' f
: [ s$ s* F. R8 v( Z5 s; @
但是后面的内容没有3、4、5脚,却是这样写的:
$ ]0 r$ L7 |7 K$ Y& r5 O.SUBCKT TS393 2 1 44 55 33% A6 Z4 Y* ?( x. @9 B3 ?
t" P! N+ e- \; B! {9 ^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?
