@(initial_step) integ = 0;
@(cross(V(ctrl), +1)) integ = 1; // triggers when V(ctrl) crosses 0 in the positive direction @(cross(V(ctrl)-2,+1)) integ = 0; // triggers when V(ctrl) crosses 2 in the positive direction
V(out) <+ idt(integ * V(in), 0);
Note that V(ctrl) must start below zero, or else the cross function won't detect a crossing.
