标题[问题] About Hspice
时间Fri Jun 26 00:59:40 2009
Hello!
I have a problem about Hspice.
I want to sweep my circuit by different Vth.
It needs to change parameters in model card, but I don't want to do it
manually.
Here I came up with a idea that I made lots of model cards with different vth
and use .alter to run circuit.
Does everyone know some syntax or better way to do?
Thanks for your reading!

1F：推 ultimachen:you can simply series a voltage source at gate node 06/26 01:19
2F：→ ultimachen:by adjusting the voltage of voltage source 06/26 01:19
3F：→ ultimachen:the equivalent vth is vth+vos 06/26 01:20
4F：推 deathcustom:which level is your model card? 06/26 01:57
5F：推 pow:in the model library you can assign vth to a parameter 06/26 05:02
6F：→ pow:vth0=vth_fubar then in the main netlist use .param 06/26 05:03
7F：→ pow:in that case, you can sweep the parameter 06/26 05:03
