TEXT -128 -368 Left 0 ;Edge speed improvement after an idea from "analogspiceman"\n \nAdding "tripdv=1u tripdt=1p" improves the edge speed million times.\nThe simulation with this method is at least 5 times faster as with the \nRLC-network used in "Edge_enhancement2.asc"\n  \nPlot V(int)  to see the "sharp" edges.
