15.0 DESIGN CHECKLIST
The checklist below is intended to help ensure that the correct connections have been made in a design. The check items
describe connections for the various interfaces and the “Same/Diff/NA” column is intended to be used to indicate w hether the
design matches the check item description, is different, or is not applicable to the design.
