all the better. i'm still convinced that the pulse should evaluate to iv at delay. or more general it should evaluate to the value before a transition until after the transition has started. (your patch does not affect this). here's another example. """ spice V1 1 0 pulse iv=0 pv=1 .print dc v(nodes) .dc .print tran v(nodes) .tran 0 1m 1m trace=a .end """ imo the initial DC should yield v(1)=0. consider an additional resistor(1,2) and a capacitor(0,2). only an empty capacitor at time=0 makes sense to me. now if spice does replace rise with something positive, it should also end up with an empty cap in .dc. thanks felix _______________________________________________ Gnucap-devel mailing list [email protected] https://lists.gnu.org/mailman/listinfo/gnucap-devel
