The environment section contains a variety of user preferences that help customize the schematic canvas view.
Canvas colour when viewing definition: Choose a colour to help visually differentiate the instance domain from the definition domain. This option becomes helpful especially when working with modules having multiple instances. See Multiple Instance Modules for more details.
Prohibit canvas modification: Enable this option to prevent the accidental modification on focus circuits during simulation.
Tool-tip animation: Controls the animation of tool-tips on popup.
Animated Graphics refresh rate: Select a real-time value, by which animated graphics will refresh. Note that this refresh rate can affect simulation speed.
Identifier display: Controls bus identifier information display.
Voltage display: Controls bus voltage information display.
When hovering over: If set to Show bounding box, a dashed box will appear surrounding the component over which the mouse pointer is situated.
Scaffolding: Draws a bounding box and diagonal to show the footprint of components on the screen.
Sequencing: During the compile sequencing, this option will flash highlight each component that includes dependencies to aid in debugging.
Internal port connectivity: Controls the connectability of component ports that are set as internal.
Graphing tools rendering: This option can improve the visual quality of all graphics (GDI+), including circuits, graphs and meters. The aesthetic improvement comes at a cost in terms of processor time, so for large cases this option should be left as Best speed until runtime has ended. GDI+ can then be enabled and the canvas refreshed.
Panel appearance: Select a preferred panel style for control panels and graph frames. The choices are Plain Paper and 3D Shadow Filled.
Control panel auto-resize: This option controls the reaction of control panels to the deletion of control interfaces within it.
Graph flyby order: Select the order of the columns that appear in the graph flyby windows.
Graph flyby precision: The display precision (number of decimal places) in the graph flyby windows.
Junction appearance: Set this option to Display solder joint to show connection symbols at all overlapping signal junctions. This feature is used mostly to detect overlapping wires and possible short circuits. Once debugging is complete, this option should be turned off on larger projects, as it can add significant build time.
Overlap appearance: Places a jumper graphic at overlapping, but unconnected, wire junctions, for better appearance.
When adjusting: When Snap to canvas grid is selected, wire end points will always snap to the canvas grid when being adjusted.
