I'm having troubles writing conditional specifications in ADE-XL and am wondering if anyone has good suggestions.  Here is a simple example:

circuit:  tunable lowpass filter
simulation:  ac sim that measured -3 dB bandwidth
parameters:  frequency control, PVT

so what I want is to run a bunch of simulations over PVT and with the frequency control at min and at max.  My specs would be then:

BW_sim@control=min < minimum bandwidth spec
BW_sim@control=max > maximum bandwidth spec

In other words, the sim looks over PVT and makes sure the desired range of bandwidths is achievable over all PVT.

I don't know how to make the measurement in ADE-XL depend on the frequency control parameter.

Thanks
