useOneSlotSpecCell

slt useOneSlotSpecCell boolean { t | nil }

Description

When set to nil, a list of defined contexts is visible in the Context field of the Slot Geometry tab of the Metal Density Options form. Instead of the string field for the Specification Cell, a drop-down list is available, which lists the contexts that have been defined using the sltSetContextSpecificationCells SKILL function. The default is t.

If set to t, you can specify the slotting parameters only for a single specification cell. In the Metal Density Options form, a string field is available to specify the specification cell name in the library/cell/layout format.
