OrCAD X Resources

14. Then the LS1 (No layers defined) list will appear, and you can click the arrow to expand the list. 15. Select the checkboxes for the TOP, GND, POWER, and BOTTOM layers (see below). Click Apply then OK. 16. You'll be taken back to the Select Layer Sets window. Choose the LS1 item, then click the > arrow to move it to the right column, then click OK. 15 www.cadence.com OrCAD X Constraint Management Guide
