Improving TSU

• Try turning on the Fast I/O logic option for the entire project or for individual input pins:

  • The Fast I/O logic option will allow input pins to directly drive macrocell registers via the fast-input path (MAX 7000)
  • This will allow registers to be implemented in the I/O Cells adjacent to the input pins instead of in the macrocells (MAX 9000)

• Reduce amount of logic between the input pin and the register (or pipeline)

• Reduce fan-out

• Use Row pin instead of Column pin for data input (MAX 9000)

• Place data input and register closer together
