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:

H0 X, q% o7 `& s% z) J但是后面的内容没有3、4、5脚,却是这样写的:
+ x4 V d1 g( W.SUBCKT TS393 2 1 44 55 33% v9 g2 Y+ Y0 T
: e y V; m+ Z8 E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?
