Device Timing: Clock-to-Out

• Register Clock-to-Q Time (See Data Book)

• Clock Delay Depends on Resource Used
  • Dedicated Inputs Drive Global Nets
  • I/O Pins Drive Row & Column Interconnects

• Data Delay Factors
  • Proximity of Output Pin & Register

• IOE Register always provides fastest clock-to-output (FLEX 8000)

tCO = Clock Delay + Register Clock-to-Q Time + Data Delay
