When used properly, clock enables can significantly reduce design power with little impact on area or performance. However, when clock enables are used improperly, they can lead to:

  • Increased resource utilization
  • Decreased placement density
  • Increased power
  • Reduced performance

In most cases, low fanout clock enables are the main contributor to the high number of control sets.
