vxlInstSpacingDir Property

vxlInstSpacingDir list (left right top bottom)

Description

Assigns automatic spacing properties to pins of instances.

If these pins are on different nets or the pins cannot abut for any reason (for example, they are not assigned abutment properties), the software automatically separates the instances by the distance and in the direction you specify.

If one of the devices is in any type of group (including a synchronous clone), the other device must be in the same group for automatic spacing to occur.

If you want automatic spacing to apply to Cadence® SKILL language or technology file parameterized cells (Pcells), you can enter these properties in SKILL to add the spacing properties to the pins.

If you want automatic spacing to apply to standard cells, you can enter properties on the pins.

If the vxlInstSpacingRule Property value is different for two pins affected by Space components, the larger of the two values is used; if the value is defined for only one of two pins affected by Space components, the defined value is used.

Use the Layout XL user interface to enter properties on the pins in the same way that you enter the permuteRule properties.

To add the access direction to the pin:
