Original question:
[参考译文] TLC555-Q1：您是否有 LTSPICE 模型？
请教贵司提供的模型spice模型到LTSPICE仿真软件中提示无法解析是怎么回事？
您好，
我查询了这个问题中出现的报错，很多客户反应是由于没有定义 VT ，请尝试通过定义VT来解决问题。
具体请参考下面几个帖子：

能讲大致讲讲操作步骤吗？是模型里只要有Vt在20°C都定义25mV,其它还需要修改改些什么？
您好，帖子都看了吗?这里面有用户和您类似的问题，是通过定义“VT”解决的问题，请注意PSpice 模拟器默认将 Vt 设置为 25mV。您可以尝试客户的方法：e2e.ti.com/.../3315466
