[[RF.Spice]]'s schematic editor allows you to enter and build up your circuit design very quickly. [[RF.Spice A/D]] offers one of the easiest and most intuitive schematic editors currently available in the market. When building a new circuit, you add parts into the circuit window by choosing them from [[menus]] or from the Toolbox or simply using [[Keyboard Shortcuts|keyboard shortcuts]] like R, L, C, Q, etc. Then, you draw wires to connect the parts. You will also set properties for the devices to customize their behavior. <table><tr><td> [[File:b2MAN_Fig211.png|thumb|left|720px| RF.Spice A/D Schematic Editor.]]</td></tr></table>

You can choose from a list of the most commonly used parts directly from the Parts Menu. This menu is a quick way of selecting a generic or popular example of a type of part. It also contains the basic parts common to most circuits, such as resistors, capacitors, and inductors. Most generic parts have [[Keyboard Shortcuts|keyboard shortcuts]]. For example, you can place a resistor, capacitor or inductor by simply typing R, C or L on the keyboard, respectively. Click here for a list of [[List_of_RF.Spice_A/D_Keyboard_Shortcuts | Keyboard Shortcuts]].

The newest method for [[placing parts]] is the '''Parts Bin''' tab of the Toolbox. In the Parts Bin tab, parts can be browsed and selected in four ways:

<b>Category</b> - This is the default selection method, where parts are grouped by category in pop-up [[menus]]. Navigation is as easy as following the categories down to the specific category you want, which will then bring up a Parts Browser window with the desired category pre-filtered.

Wires can be automatically drawn and broken (redirected) at 90 degree angles. This feature can be turned on either from the Edit > Schematic Options menu or from the [[Schematic toolbar|Schematic Toolbar]]. In this case, wires will be drawn at the nearest 90 degrees to where the previous wire was segment ended. Wires can also be set to snap to the grid by choosing the respective option either in the Edit > Schematic Options menu or from the [[Schematic toolbar|Schematic Toolbar]].

Every node in your circuit has a unique number or name. <b>Node 0 is always reserved for the Ground</b>. To display the node numbers or names, click the "Show Node Names" button of the [[Schematic toolbar|Schematic Toolbar]] or use the keyboard shortcut {{key|Ctrl+Alt+N}} or check the Nodes items from the View > Show menu.

[[File:b2MAN_Fig104.png|thumb|400px| Schematic Options Dialog's Display tab.]][[File:b2MAN_Fig105.png|thumb|400px| Schematic Options Dialog's General tab.]]The Schematic Options dialog can be opened from [[Schematic Editor]]'s Edit Menu and provides a large number of options to customize the appearance and functionality of the [[Schematic Editor]] to your personal preference. The dialog has three tabs: Display, General and Print.

The Schematic Display section allows you to customize the appearance of the schematic. "Show Grid" turns the schematic grid on or off. "Show Schematic Border" toggles the top and left location borders. "Show Page Boundaries" shows the printed page boundaries as a dashed line. The printed page size and orientation can be changed from the "File > Page Setup" menu. "Show Title Box" toggles the Title Block for each page. "Show Node Names" toggles whether or not node data is displayed. This is useful for associating data from simulation results with actual nodes in the circuit. All these toggle functions can also be accessed from respective buttons on the [[Schematic Editor]]'s Toolbar. The "Text Field Font" button sets the font properties for text drawn with the Text Tool. The "Segment Color" and "Vertex Color" buttons are used to customize what colors the wires and vertices are shown in. The node names/node voltages/branch current/power fonts buttons control the various fonts used for the State Display fonts. <table><tr><td> [[File:b2MAN_Fig104.png|thumb|left|480px| Schematic Options Dialog's Display tab.]]</td></tr></table>

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.
