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：

. @$ d: v9 B# U4 c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？; P ~# e- y) P+ g9 D% 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：
