How do I measure voltage at trigger signal with MDL?

[jacunski]

Can anyone tell me how to measure a voltage at a specific trigger time
using SpectreMDL?

For example, I'd like to measure the voltage on net1 when net2 passes
through a particular voltage. This can be done in HSpice as follows:

.meas tran vsignal FIND v(net1) WHEN v(net2)=0.5 RISE=2

Thanks.

Mark,

The equivalent in MDL is

export real vsignal = V(net1)@cross( V(net2), thresh=0.5, dir='rise,
n=2 )

You could write it a couple of different ways, e.g.

export real vsignal = V(net1)@cross( V(net2)-0.5, 'rise, 2 )

But the first is probably the most efficient.
