General

Snap Mode

Controls how the cursor snaps to the grid when you create a bus.

• anyangle: Creates wires at any angle. Can only be specified when using paths to create wires.
• diagonal: Creates wires parallel to the X or Y axis or at a 45-degree angle to the axes.
• orthogonal: Creates wires parallel to the X or Y axis.
• L90XFirst: Creates orthogonal two-segment wires and creates the first line in the X direction.
• L90YFirst: Creates orthogonal two-segment wires and creates the first line in the Y direction.

Environment variable: snapMode

Cover pin

Adjusts the wire segment to automatically cover the source and target pins. Otherwise, the wire segment is not adjusted and the wire terminates at a point you had chosen. By default, this option is deselected.

Environment variable: weCoverPin

Auto terminate

Finishes the interactive routing command as soon as a point is digitized on a flightline target object (pin, existing wire, or via). All wires snap to the target pin.

Allow loops

Permits creation of loops when creating or editing wires. The option is off by default. When off, the Create Wire command does not allow the creation of loops on the same layer. When the layer is changed while wire creation, loop checking is reset and applies only to the new layer.

Environment variable: allowLoops

Auto merge wires

Automatically merges the connected paths and collinear pathsegs while creating or stretching a wire. The check box is selected by default. To prevent automatic merging of collinear (symbolic or geometric) wires, disable the Auto Merge Wires option.

Environment variable: weAutoMergeWires

Via

Adjust edited via params

Enables the re-calculation of via alignment of the vias if you stretch the wires connected to them. This check box is not selected by default.

Environment variable: adjustEditedViasParams

Override variants

Lets you specify a custom via alignment option that overrides the automatic alignment.

Cut Enclosure Minimum

Specifies the via cuts as minimum number of cuts for creating and editing wires. If the override value is less than either the technology rule or the current constraint group on the net or on the design, then the specified value is reset to the minimum value.

Cut Spacing

Lets you select the spacing for the number of cuts that can be added to a via. You can either select the minimum spacing between the via cuts or evenly distribute the via cuts.

Calculation Mode

Sets the calculation mode for via parameters to one of the following:

• Min Rules & ViaDef : For all the via parameter fields, such as the number of cut rows and columns, and cut sizes, the minimum rule or the viaDef default values, whichever is greater, are used. If minimum rules are not defined, viaDef defaults are used. The spacing and enclosure values are calculated automatically from the minimum rules. The minimum rules are picked from the constraint group that you select from the Via list in the Create Via section. The calculated values for the spacing and enclosure fields are never less than the viaDef defaults. For example, if the minExtensionDistance rule is 0.05 and the default enclosure in viaDef is 0.1, 0.1 is used as the enclosure value in the Create Via form. Similarly, if the minSpacing rule is 0.2 and the default cut spacing in viaDef is 0.18, 0.2 is used as the cut spacing X and Y in the Create Via form.
• Minimum Rules : For all the via parameter fields, only the minimum rules, such as minWidth and minSpacing, are used. For example, if the minExtensionDistance rule is 0.05 and the default enclosure in viaDef is 0.1, 0.05 is used as the enclosure value in the Create Via form. The viaDef default enclosure value is ignored.
• ViaDef Defaults : For all the via parameter fields, viaDef defaults are used. When ViaDef Defaults option is selected, the via engine does not check any rules.

Via Alignment

Lets you align vias as they are digitized during wire or bus creation. You can choose to align a via either automatically or by selecting a custom alignment option. Vias are aligned between the edges of via enclosure shapes and the edges of the connecting wires on the same layer. For example, for a Metal1 to Metal2 via, the via location is adjusted in a way that the Metal1 wire edge is aligned with the Metal1 via enclosure and the Metal2 wire edge is aligned with the Metal2 via enclosure. The alignment offsets the via origin to maintain it at the intersection of the wire end points. If you are adding and aligning a via stack, the same via alignment is applied to all the vias in the stack.

You can also access the via alignment options from the Create Stranded Wire Form.

Environment variable: autoViaAlignment

Orthogonal Transitions

Controls alignment behavior for orthogonal transitions.

• In and out layers: Aligns to the edges of both incoming and outgoing layers. This is the default option.
• In layer only: aligns to the edge of the incoming layer only.
• Out layer only: aligns to the edge of the outgoing layer only.
• None: if selected no alignment is done for a via.

Environment variable: autoViaAlignmentOrthoTransitionBehavior

Collinear Transitions

For colinear transitions controls alignment behavior for colinear transitions.

• In and out layers: Aligns to the edges of both incoming and outgoing layers. This is the default option.
• None: If selected no alignment is done for a via.

Environment variable: weTrimTrimPurpose

Bridge Purpose

Specifies the purpose on which the bridge should be inserted. If no value is specified for the purpose, the bridge is not inserted. However, if the specified purpose is invalid, the bridge is inserted on the default purpose. The default purpose is drawing.

Environment variable: weTrimBridgePurpose

Patch Purpose

Specifies the purpose on which the patch segment should be inserted.

Width

Width Mode

Sets the width mode to one of the following:

• Same for all layers: Specifies to use the same wire width for all layers. The width value is determined by the value specified in the Width field of the Create Wire form. The constraint overrides for all layers are available in the Wire Assistant table.
• Overrides by layer: Sets the wire width the same as the result of the constraint lookup for minWidth in the technology file when the layer is not used. Else, the width is determined by the last width used for the layer. The width value from the Wire Assistant table can also be used for the wires on each layer. You can also use the value specified in the Width field for the wires on each layer.
• Default Constraints: Sets the wire width same as the result of the constraint lookup for minWidth in the technology file or in any applicable constraint group defined at the design or object level.
• Source Objects: This is the default option. The source object can be pins or wires. It is specified to use the maximum width determined by the width of the tapped object. Selecting the Source Objects option for the first segment of a wire ensures that Tap Wires Width or Tap Pins Width is selected, depending on the source object. You can also select Source Objects even if the first segments of the wires does not have the source object width. In such a case, the Tap Wires Width and Tap Pins Width option does not change.
• Target Object Narrow: This option matches the last segment wire width to the length of the shortest edge of the target pin. The width of the remaining wire is unaffected.
• Target Object Wide: This option matches the last segment wire width to the length of the longest edge of the target pin. The width of the remaining wire is unaffected.

Width

minNumCuts

Specifies the minimum number of cuts that can be added to a via. You can override the minNumCut rule value for creating and editing wires. If the override value is less than either the technology rule or the current constraint group on the net or on the design, then the value is reset to the minimum value.

Row/col

Specifies the via cuts as the number of rows or the number of columns. By doing this, you can override the minNumCut rule with a more explicit configuration for creating and editing wires. The increase and decrease in the number of via row and column is dependent on the minimum number of via cuts.

number of via rows * number of via columns >= minimum number of via cuts. 

Maximize cuts

Lets you get a larger cut size depending on the added metal.

Snapping & Tapping

Smart Snapping

Controls how the cursor snaps when you create the wire.

Tap Layer

Taps the routing layer. Layers that can be tapped are determined from the technology file.

Tap Width Enable

Enables width tapping for objects: wire, via, and shapes and pins.

Wire

Taps an object's layers and attributes automatically when digitizing the first coordinate of a wire.

Via

Taps the width on the starting object for new wire when the starting object is a via. The edge of the via determines the width of the started wire.

Shape and pin

Taps a top-level shape, a top-level pin, or a level-1 instance layer and width attributes. The objects type is either a rectangle, a polygon, or a path. All valid routing layers can be tapped.

Snap To

Controls the snapping of wires to a grid.

• Off Grid segments and vias can be created or moved anywhere without snapping.
• Manufacturing Grid, snaps the wires to the manufacturing grid. This is the default option.
• Routing Grid snaps the segments and vias other than the ones directly connecting to the off-grid pins to the routing grid.
• Track Pattern snaps the segments and vias other than the ones directly connecting to the off-grid pins to track. The track patterns are saved on the design and so each design can have its own set of non-uniform track patterns.
• Snap Pattern enables snapping of wires to the nearest snap pattern track.

Pin center

Snaps wires to the center of rectangular pins or of pins that are created as polygons and have rectangular shapes. If this check box is selected, wires snap to the starting and ending pins. The Pin Center check box is deselected by default.

Via center

Snaps wires to the center of vias. If this check box is selected and you click a via, the starting wire starts from the clicked point and two small segments are added to connect to the via origin. With this check box selected, tapping a via and a wire gives preference to the via. This check box is deselected by default.

Halo

Controls the display of halos in the layout canvas in order to make it easier to view them in the design.

Show hints

Controls the display of the Interactive Routing Bindkey hint box in Layout EXL when you start the Create Wire, Create Bus, or Create Stranded Wire commands. In Layout XL, the hint box is displayed only for the Create Stranded Wire command. The Interactive Routing Bindkey hint box describes the useful bindkeys and shortcuts for the interactive routing commands. This option is selected by default.

Alignment Markers

Dynamically displays an alignment arrow and an alignment marker. The arrow points to the closest object on the active flightline. The marker snaps the cursor to the target object edges and center as you move the cursor.

Environment variable: showAlignmentMarkers

Flightline

Controls the display of flightlines during wire creation. You can hide the display of flightlines by setting it to off or display only three flightlines for each bus by setting it to minimum. The default is on.

Constraint Group

Specifies the name of the constraint group that contains the foundry constraints.

Nets

Lets you specify the net names for creating a bus. You can specify the net names in one of the following ways:

• By specifying a bundle name, such as netA, netB, netC<1>, netD, where the net names are separated by commas.
• By using the bus notation, such as net<0:3>. If you specify the net names in bus notation, the notation expands to display individual net names, such as net<0>, net<1>, net<2>, net<3>, in the Net Name field when you move the cursor to another field in the form. The number in the Number of Bits cyclic field updates based on the number of nets specified in the Net Name field. For example, the Number of Bits cyclic field updates to 4 for the bus notation net<0:3>.
• By specifying a bus base name, such as netA or myBus, and additionally setting up the bus cardinality in the Number of Bits cyclic field. The bus base name expands to display individual net names in the Net Name field only after you start creating the bus. For example, if you start creating a bus by specifying the bus base name as netA and setting the Number of Bits cyclic field to 10, the bus creation begins with 10 wires that are assigned to the netA<0>, netA<1>, netA<2>, ... , netA<10> nets.

New nets are created if the ones specified do not already exist. If you start creating a bus from existing pins, the net names are automatically picked from the net of the pins. If you create the bus in free space without specifying any net names, the bus created is not assigned to any net and therefore, does not have any connectivity.

Environment variable: netName

Width

Number of Bits

Specifies the number of wires in an unassigned bus. The default value is 2.

• In the Nets field, if you specify net names as a bundle name or by using the bus notation, the value in the Number of bits cyclic field automatically updates to match the number of nets specified. If net names are specified in the Nets field and you manually update the value in the Number of bits cyclic field, the net names specified in the Nets field are removed.
• In the Nets field, if you specify the net names by using the bus base name, you can set up the cardinality of the bus by using the Number of bits cyclic field. The bus base name expands to display individual net names in the Net Name field only after you start creating the bus. If you update the Number of bits cyclic field after starting bus creation, the net names are removed from the Net Name field.
• If you change the number of bits from the default value, which is 2, to any other value, and then specify the net name, the number of bits does not get reset to default value 2. The last changed value is retained in the Number of bits cyclic field.

Environment variable: weBusNumBits

Width Mode

Sets the width mode to one of the following:

• Same for all layers: Specifies to use the same wire width for all layers. The width value is determined by the value specified in the Width field of the Create Wire form. The constraint overrides for all layers are available in the Wire Assistant table.
• Overrides by layer: Sets the wire width the same as the result of the constraint lookup for minWidth in the technology file when the layer is not used. Else, the width is determined by the last width used for the layer. The width value from the Wire Assistant table can also be used for the wires on each layer. You can also use the value specified in the Width field for the wires on each layer.
• Default Constraints: Sets the wire width same as the result of the constraint lookup for minWidth in the technology file or in any applicable constraint group defined at the design or object level.
• Source Objects: This is the default option. The source object can be pins or wires. It is specified to use the maximum width determined by the width of the tapped object. Selecting the Source Objects option for the first segment of a wire ensures that Tap Wires Width or Tap Pins Width is selected, depending on the source object. You can also select Source Objects even if the first segments of the wires does not have the source object width. In such a case, the Tap Wires Width and Tap Pins Width option does not change.
• Target Objects: Sets each bus wire to match the width of the same edge of each respective target pin. If the pins are vertically aligned to bus wires, the bus wire widths match the width of the vertical edges of the respective target pins. Similarly, if the pins are horizontally aligned to bus wires, the bus wire widths match the width of the horizontal edges of the respective target pins. The horizontal and vertical edges might correspond to narrow edges for some target pins and wide edges for other target pins. This option cannot be selected and you need to use the Target Pin Narrow Edge or Target Pin Wide Edge options depending on the edge whose width you want. The narrow and wide edges for target pins is only applicable in case of single wire creation.
