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：
- f5 d( o( R3 b4 P o* TS393 spice macromodel: P& k% i$ O5 t2 Y( n4 k
* CONNECTIONS :( a& }* U- J/ X8 `4 w% k) m

# M- `6 o4 H" T7 F% G* 5 OUTPUT
4 z) k# z7 s9 d4 m3 O% U8 i3 ?2 X, z4 a( R: i1 G5 w
但是后面的内容没有3、4、5脚，却是这样写的：
) S' K0 [! I v( b$ P$ `.SUBCKT TS393 2 1 44 55 33. D+ F o1 `: l
, S1 K6 y* g( ^" r- V
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？8 z! z/ x+ B$ F2 F2 H3 Z6 j

。不知道你哪里有没有比较详细的Spice方面的资料？你说的那个我现在明白了：
