Buffer Primitives

Buffer primitives allow you to do the following:

• Make a location assignment
• Make an I/O standard assignment
• Make a drive strength (current strength) assignment
• Make a slow slew rate assignment
• Enable bus-hold circuitry
• Enable a weak pull-up resistor
• Make an on-chip termination assignment to a bidirectional pin from a lower-level entity

The following buffer primitives are available:
