3. Once created, we will copy existing constraints from DIFF into this new ECSet we just made (DDR2_D0_DIFF). Right click
on the DDR2_D0_DIFF ECSet, then choose Copy Constraints From (shown below).
4. You get a new Select Object window. Choose the DIFF constraint set to copy the constraint values from, then click Ok.
5. Notice the values are populated immediately afterward for DDR2_D0_DIFF.
Exercise: Modify the constraint values as required for your ECSet, based on your design guidelines.
