Dear All

How can I use Hspcie to simulate phase margin v.s. load capacitance

Y axis is phase margin
X axis is load capacitance

I use .measure to get phase margin but I can't plot it on spice explore.
Could you give me some Hspice code to do this simulation?

Thank you

just like this plot :

Dear JobsEDA:

1. set .param of cload
2. sweep cload in .AC
3.use .meas or .probe to get phase margin.
