I wanted to use a behavioural voltage source to simulate a zero-crossing detector, but have run up against a problem: it appears to give up the ghost (in both LTspiceIV and LTspiceXVII) when the dV/dt of the waveform exceeds a quite modest value. Is there a parameter in Control Panel which can be tweaked to get round this?

Interesting. Perhaps the response to the maximum step size setting is processor speed dependent? Wish I was more spice-literate to know what the various settings do .
Hmmm...Out of curiosity, I reset all my setting to default (they already were set to default), and reran the simulation.
Still ran ok without modification.
PC- CPU Q6600, SSD, 3Ghz, Win10, LTspiceIV
Also tried this on PC - 4.5Ghz, SSD, Win10, LTspiceXVII. Same result...no errors
