hspice parametric analysis

[jutek]

hello

could you tell me how to set ac analysis with different load?

i use .data directive and then sweep it in ac analysis but when i plot it in the awaves the x-axis is not frequency but load steps values.

regards

you can simulating specialty or loading simulating results by matlab

use .alter directive

use .alter directive

i don't want to use .alter cause i have to check several loads.

i though it's possible in a different way. yes, matlab is ok, but i'm lazy and want everything in one simulation

.data directive should give me what i want to, but it doesn't work properly. maybe some simulation options i should add to?

.ac sweeptype(dec etc...) start stop sweep variable start stop step.
For example: .ac dec 100 1 100meg sweep cload 1p 50p 2p
