Edit Pin Order Form

Move Up moves the selected pin up one position.

Move Down moves the selected pin down one position.

Move To Top moves the selected pin to the top of the list.

Move To Bottom moves the selected pin to the bottom of the list.

Reset Order resets the pin order to the default order. The default port order is output input inputOutput, and the pins in each type are sorted alphanumerically.

Copy From copies a pin order property from a list of available views.

Editor Options Form

Add Instance Browser Type specifies which browser the system opens when you click on the Browse button on the Add Instance form.

library (default) specifies the Library Browser.

component specifies the Component Browser.

Block Pin Direction Rule specifies which pin direction rule the system uses to create pins automatically when you connect a wire to a block.

edge (default) specifies the pin direction based on the edge where the system creates the pin. When you add a wire to the left edge of a block, the system creates an input pin. When you add a wire to the right edge of a block, the system creates an output pin. When you add a wire to the top or bottom of a block, the system creates an I/O pin.

order of entry assigns the pin direction based on how you implement the Add Wire command. When you start a wire from the edge of a block, the system creates an output pin. When you terminate a pin on the edge of a block, the system creates an input pin.

Wire Snapping lets you use the s key to quickly complete a wire drawing action. When wire snapping is enabled, the system highlights an unconnected pin in the design when you move the cursor near the pin.

Automatic Solder Dots when enabled (default), automatically creates a solder dot when you create wire intersections. The system does not create solder dots when you draw a wire over another wire.

Solder Dot Wire Overlap specifies the amount that a solder dot extends outward from the thickest wire segment the dot connects.

Symbol Generator Pin Sorting specifies how the text-to-symbol generator sorts the symbol pins onto the edge of the new symbol.

alphanumeric sorts pins by pin name.

geometric sorts pins by their relative positions in the schematic and is valid only when a schematic exists for the specified cellview.

Add Symbol Pins as Instances specifies how the symbol editor creates pins when you add pins to a symbol using the Add – Pin command or creates a symbol using the Create Cellview – From Cellview command.

off (default) creates a graphical symbol pin shape based on a symbol pin master. After you place symbol pin shapes, any changes you make to the original symbol pin master do not affect the symbol pin shapes based on the symbol pin master.

on creates an instance of a symbol pin master. After you place symbol pin instances, any changes you make to the symbol pin master also affect the appearance of all the existing instances created from the symbol pin master.

Modal Commands specifies whether repeatable commands remain active after you complete an action.

off specifies that repeatable commands cannot be repeated.

on (default) specifies that repeatable commands remain active until you press the Escape key. However, some repeatable commands do not remain active when you enable this option if you have preselected an object. The Copy, Move, and Edit commands are examples of such commands.

Cross Selection controls whether object selection is exported to other tools.

off (default) does not export the selection to other tools.

on exports the selection to tools that are open and which can support the selection.

Minimum Marker Size specifies the minimum size of any error or warning markers that the system generates when you check your design.

View Name List displays a series of view names listed in the order you want the editor to display them, if they exist. You use View Name List in conjunction with the Hierarchy – Descend Edit and Hierarchy – Descend Read commands.

Bus Range Order specifies which order the system uses to generate buses. The default is ascending.

Net Name Method specifies a net naming mechanism for schematic extraction.

prefix (default) generates a unique name for nets that you do not explicitly label or connect to a pin. The unique name consists of the prefix that you specify in theNet

Name Prefix field followed by a number.

derived generates a net name from the driving instance name and the driving terminal name. The derived net name is of the form instName_pinName.

Net Name Separator specifies the field separator for derived names. The underscore character ( _ ) is the default separator. You can edit the separator when you select the derived option in the Net Name Method field.

Net Name Prefix specifies the prefix for all new net names generated by the editor. The default is net. You can edit this field when you select theprefix option.
