Improved Impedance Control

An enhanced 'Layer Stack Editor' has been implemented and new functions to control impedance have been incorporated into the dialog. It is now much easier to set the width and spacings in order to achieve target impedance values for single ended nets and differential pairs.

Controlling the impedance of electrical nets and differential pairs can now be done using impedance templates. An impedance template can be defined in the new 'Layer Stack Editor' and allows you to control the widths and impedances to be used for any layer in the design. Once an impedance template has been defined, it can be applied to different design items to control the routing widths.

The following options have been added to Constraint Manager for impedance templates:

A new 'Edit -> Set Impedance Template' menu option is available, and there is a new 'Set Impedance Template' option on the tree view context menu;
