各位大佬好，刚入门的幼儿园小学生一枚

Ubuntu18.04LST + IC617
我从这里下载了TFET的相关的文件（用到的就只有ndtfet.va和ndtfet.lib两个文件），然后在Hspice中跑了一个简单的反相器，出来的波形是对的，
然后我准备用ndtfet.va这个文件，在cadence中生成两个symbol，导入步骤是看YouTube上的视频，第一次导入的时候（导入n型），我在cell name中写的是ntfet，Type是VerilogA,内容是下面的第一个代码，第二次导入的时候（导入p型），

我在cell name中写的是ptfet，

Type是VerilogA,内容是下面的

第一个

代码，其中第76行

parameter integer type = `n_type;

复制代码

我给改成了

parameter integer type = `p_type;

复制代码

目测这条语句是来控制管子类型的吧

希望我没有理解错，，然后单独看n型(或p型)的D端电流随D端电压变化，n型是对的(

也可能是错,只是凑巧看着是对的，毕竟只做了一个电路简单看了一下，原谅我不知道怎么看是对是错

)，单独看p型是不对的，做成反向器也是不对的。

请知道的大佬提醒一下需要注意的点，如果能有点教程(怎么导入n型和p型)就最好了，，，谢谢大佬们。
