Well done CL!

You've made a Laplace block that converges and gives realistic, accurate results in a feedback loop.


Time Domain simulations with a Laplace block in a feedback loop can lead to all sorts of trouble.

In SIMetrix, about the best commercial Spice simulation package available, they converge and give very accurate results.

In PSpice, the "Industry Standard" spice simulation tool, unrealistic spikes appear on the edges.

They fail to converge in LTspiceIV and ngspice.

In CL this example converges and gives results comparable to the same circuit run in SIMetrix.

Well done CL!
