7 segment octal decoder

We found many implementations, but we think that our versions will overperform any other (please send us your version, if it is better)!





Truth table




Gate-level netlist designed by Vivado Design Suite (Developer: Xilinx, AMD):

Our schematic version:

Our version of 7 segment octal decoder circuit outperforms the Vivado Design Suite version in several key areas:
  • it reduces power consumption by 1.42 times,
  • improves delay (performance) by 1.24 times,
  • decreases area requirements by 1.45 times,
  • cuts gate count by 1.35 times,
  • reduces transistor count by 1.57 times,
  • and lowers wire usage by 1.28 times.
