New Animated Schematics

This revolutionary feature shows the connecting wires changing shape and color to reflect current and voltages in the circuit, with respect to DC stepping, frequency sweep and time. Relative voltages are color-coded to magnitude and arrows display the actual current paths as they flow within the circuit. In other words, now you can see into the circuit.

"Circuit animation gives me both general and specific insight into the behavior of the circuit as the simulation is running.  For example, I was building an amplifier today and I noticed that the current through the emitter of a key transistor was changing direction, implying avalanche breakdown in the base-emitter junction.  Without circuit animation, I never would have realized that this was occurring,"

said John Broskie, editor of the Tube CAD Journal
