PSPICE模型param问题

Panc

在把spice模型转成pspice模型的过程中遇到问题，双脉冲仿真显示参数没有定义，但是在模型的开头已经完成了所需参数的定义；想请教大家该如何解决这个报错
param定义：

.PARAM  T0=25
+ Vth0=0.30        Vth_tc=-14m
+ Vtmin=0.30      
+ Vtmax=1.33
+ alpha=0          beta=0         gamma=0
+ ksat=0.8
+ dR=0  
+dVth=0  
+dCi=0  
+dCr=0  
+dCo=0
+ Cgs0=1400p
+ Irrm=5.13e4
+ RR=50k           CC=1p
+ Ct0=259

* Corner scaling helpers
* limit(x,lo,hi) is PSpice builtin
.PARAM Dsoglia = {Vtmax*LIMIT(dVth,0,1)+Vtmin*LIMIT(dVth,-1,0)}
.PARAM CiScale = { 1 + (1.3-1)*LIMIT(dCi,0,1) - (1-0.7)*LIMIT(dCi,-1,0) }
.PARAM CrScale = { 1 + (1.3-1)*LIMIT(dCr,0,1) - (1-0.7)*LIMIT(dCr,-1,0) }
.PARAM CoScale = { 1 + (1.2-1)*LIMIT(dCo,0,1) - (1-0.8)*LIMIT(dCo,-1,0) }

你看下是不是T0=25 可以识别，下面的+号打头的都不能识别，你可以试下，把+号打头的parameter 都改成.PARAM  参数名 = 具体值

我试了一下，没有效果。而且各个param是可以在virtuoso里面显示出来的

把input.scs ，run cmd，输出log  贴上来看看

scs默认是spectre语法，如果用的语法是spice需要加language=spice,里面有多处语法错，可以自己查下。

我看有些教程里面是这样的，但是我看官方文档里面没有这一个步骤

我不知道要怎么关掉文件收取积分，我把log和cmd贴在下面
output log：

你的模型是spice模型，specter工具可以仿真spice模型，但是语法需要稍微改下
