Pin Assignment Guidelines

• If pins must be assigned prior to design creation, follow these guidelines

• For MAX 7000 devices:

  • Assign speed critical control signals to dedicated inputs
  • Assign output enables to appropriate locations
  • Estimate fan-in to assign output pins to appropriate LAB
  • Assign output pins in need of parallel expanders to Macrocells #4-8 or Macrocell #12-16

• For MAX 9000 devices:

  • Assign bidirectional I/Os to Row pins
  • Assign speed critical, low fan-out inputs to Row pins
  • Assign high fan-out inputs to Column pins
  • Assgin wide buses to Row pins
