Use Volta to design analog circuits. Volta features schematic editing, an expandable component library, SPICE simulation, graph plotting and support for creating sub-circuits.
Create circuits by dragging components from the library window or from the overhead palette strip to the schematic area. Edit the component properties in the inspector. Connect components by dragging connection lines from pin to pin. Capture circuit schematics in SPICE netlist format. Run circuit simulations and view the graphs for AC and transient analyses.
Fixes library GUI problem on OS X Mavericks.
Fixes a netlist generation problem.
