These options for the add_pci_constraints command are described
in the following sections.
-speed
The default value for this option is the maximum speed supported by the
targeted device family.
Table A–1 shows the device speed grades required for 33-MHz or
66-MHz operation, and the default speed selected by the PCI constraint
file for each supported device family.
