Calculator skill function for sampling signal on varying pulse edge

daly

Hi there,

I have been trying unsuccessfully to use the built-in Cadence calculator functions to sample an analog signal at multiple times, based on a digital clock edge which comes at non-periodic times.  Has anyone had success using the functions such as "value", "sample" or "cross" to do this?  "cross" can get me the array of times I would like to sample, but I can't find a function that gives me the value of another analog waveform based on this array of times.

If there is no way to do it using the built-in calculator, I would like to write a custom SKILL calculator function to implement this functionality.  Does anyone have a similar example program that I could use as the starting point?

Thanks!
