gapSpace
Specifies the spacing required between the signal net and its parallel shields.
This constraint is obsolete. The current method uses
minSpacing in the shield constraint group for a net to specify the spacing between signal nets and their parallel shields. gapSpace Quick Reference
Value Type
gapSpace constraints have a Value that represents the spacing, in user units, required between signal nets and their shield routes on the layer.
Examples
Sets the spacing on Metal4 between net1 and its parallel shields to 0.8.
set_layer_constraint -layer Metal4 -constraint gapSpace -Value 0.8 \
-hardness hard -group single_shield
assign_constraint_group -group single_shield -net net_1
