Re: PWL sources (was but not related to: "Discrete data points in plot view")

Chris,

It's the the micro (?) characters. Wow, that was subtle! Do a global replace to "u" and that will fix it. The pwl syntax parser obviously cannot deal with unicode characters.

I was trying to follow the given recipes. But what I didn¡¯t like with the suggestion(s) thath the rise hold and fall times would all pile ?up and would end with a significant offset at the end of my 32 pulse.

So I thought of using the absolute time points to match exactly and start a rise-hold-fall sequence relatively to the distinct points.

This would result in a line with all 0V amplitudes for the first value. I¡¯m using the following syntax but it fails:
