Hello,

I am trying to add a Discrete device (Vendor provided spice model ) to HSPICE. I have tried different type of devices to add to HSPICE but all the devices give same result. (Source voltage of PMOS follows the Drain voltage) and device is always turned on and leaking current. :shock:

I have tried >200 voltage and <20 voltage PMOS devices. But the result is same. So, by checking in the HSPICE model files thoroughtly i couldn't find any solution. Can anyone tell me if i am using the wrong syntax to just check the switching of PMOS of any parameters are missing in my code? :sad:
