PartQuestTM Explore is a complete design, modeling, simulation, and analysis environment for electronic and mechatronic circuits and systems. Full coverage for analog, digital, mixed-signal and multi-domain systems including electro-mechanical and electro-thermal. SPICE and VHDL-AMS models supported.

How do I select more than one object on the schematic?

Holding the shift key down while clicking on an object will add this object to the selected set. Holding the control key down while clicking on an object will toggle that object’s selection without changing anything else that is selected. If the object was selected, it will be deselected after you click with the control key pressed.
