Can clip() support multiple time windows?

Johanny Saenz

Hi all.

I want to calculate a waveform metric while excluding specific time intervals containing switching glitches.

The glitches occur when a control signal changes state, so I can identify the relevant time points using cross(). For a single interval, I can use something like:

clip(waveform t_start t_stop)

However, I would like to evaluate the waveform over multiple non-contiguous time windows, effectively excluding the intervals around each detected transition.

Does the Cadence Calculator clip() function support multiple time ranges, possibly using the output of cross()? If not, what is the recommended Calculator/SKILL approach to calculate, for example, ymin() while ignoring these glitch intervals?

Thanks in advance
