The Miscellaneous Options section controls some general simulation related optons. "Include netlist in general simulation log" allows you to see the text of the Netlist data file the program sends to the SPICE simulator. A better way of viewing the Netlist is by using "Create Netlist Document" from the File menu. "New devices have unique models" determines whether or not identical parts that are added to the circuit in the future will share the same models. If checked, identical devices will have unique models and their parameters are varied separately. Otherwise, each identical part will share the same model meaning that changing the parameters of one will affect all similar parts.
The Workspace Options Section controls the Workspace area of Workshop. "Show Only Active Project [[Windows]]" will force the Workspace to only show projects that have [[windows]] open. Otherwise, the Workspace will show all the projects and open [[windows]] in the workspace. The Editing Options section allows you to customize circuit drawing options. "Snap to Grid" toggles the snap feature. If turned on, devices and wires will snap to grid points regardless of whether the grid is actually visible or not. "Use Perpendicular Wires Only" toggles the ability to draw wires in 90 degree segments. "Gravity Pixels" allows you to set the distance from a vertex a wire can approach before being automatically drawn to it. "Grid Resolution" allows you to set the spacing of the grid system.
The Digital Probe and Timing Diagram section controls options for the display of digital signals. You chose between Use (1,0)" or "Use (H,L)" for logic levels, which is used by the Probe Tool to display logic levels on the wires and device pins. The section titled Symbols for New Parts affects new parts that you place in your circuits only. There are three standards to choose from. IEEE symbols are only for the digital parts. US and European symbols are the same in most cases, but differ for resistors and many digital gates and flip-flops.
