21.7.3.3 Overall I/O Constraint

Figure 21-19. Constraint Wizard – Overall I/O Constraint
þÿ

In this window you can set a default constraint for all I/Os in the design. Constraints will be applied with respect to clocks related to the I/Os. This constraint will not override existing I/O constraints.

Show I/O constraints enables you to display I/O constraints as I/O delays (minimum and maximum delays for input and output) or external setup/clock-to-out.

To set a constraint for all I/Os:
  1. Enter the Maximum and/or Minimum delays for the Input and/or Output.
  2. Click Next to go to the next step or Finish to exit the wizard.
