msShieldStyle

Determines the type of shielding to route around a net.

For interoperability with Cadence Innovus™ flows, you must set this constraint to specify shielding.

Represents a binary-encoded integer, as listed in the table below.

Split	Top	Bottom	Sides	msShieldStyle	Description
0	0	0	0	0	No shields
0	0	0	1	1	Only parallel (sides)
0	0	1	0	2	Only tandem below
0	0	1	1	3	Tandem below and parallel
0	1	0	0	4	Only tandem above
0	1	0	1	5	Tandem above and parallel
0	1	1	0	6	Tandem above and below
0	1	1	1	7	Coaxial (Tandem above and below, parallel)
1	1	1	1	15	Tandem split (Split, tandem above and below, parallel)

The following example specifies parallel shields only.
