techSetOrderedSpacingRule

techSetOrderedSpacingRule(
d_techID 
t_constraint 
g_value 
tx_layer1 
tx_layer2
) 
=> t / nil

Description

Updates the value of the constraint in the specified technology database that (a) is in the foundry constraint group, (b) is the first hard constraint with the specified name in an orderedSpacings subsection, and (c) is applied to the specified layers. If the specified constraint does not already exist, this function creates a new orderedSpacings section containing the constraint.

Arguments

d_techID	The database identifier of the technology database.
t_constraint	The name of the spacing constraint. Valid values: Any string (example: minEnclosure)
g_value	The value of the spacing constraint. Valid values: Any floating-point number, any integer
tx_layer1	The first layer. Valid values: The layer name, the layer number
tx_layer2	The second layer. Valid values: The layer name, the layer number

Value Returned

t	The spacing constraint was updated or created successfully.
nil	The technology database does not exist or the layers are not defined.

Example

techSetOrderedSpacingRule(tfID "minEnclosure" 0.6 "Metal1" "Via1")
=> t

Sets the minimum enclosure constraint for the Metal1 and Via1 layers to 0.6 user units in the foundry constraint group of the technology database identified by tfID.
