how to sweep an equation which is formed using variables?

CKAITHANYA

Hi

I created an inverter with pmos and nmos and declared their widths as variables (Wp, Wn) by keeping the lengths constant. Now I want to plot VOUT vs  VIN  for different values of Wp/Wn ratio instead of doing parametric for Wp and Wn separately. I mean there is any way for directly sweeping the equation formed by variables.

    Yeah, I agree with your approach but in case if I don't want to fix any one of the variables and sweep the ratio. Is there anyway?

    Its like if I have three variables x,y,z and there is a relation between them x*y+z =r (let's say). Now instead sweeping for all the three variables is there any way in which I sweep "r"? so that I can get random combinations of x,y,z

    No. This is not possible and I can't see it would make any sense either given that there would be no constraints on any of the variables - there are multiple solutions to that equation if you are just sweeping the result.
