Constructor & Destructor Documentation

mergeSchema::mergeSchema	(	schema *	s1,
		schema *	s2,
		double	hgap
	)

private

Constructor for a merge schema s1 :> s2 where the outputs of s1 are merged to the inputs of s2.

The constructor is private in order to enforce the usage of makeMergeSchema

Creates a new merge schema.

Cables are enlarged to dWire. The horizontal gap between the two subschema is such that the connections are not too slopy.
