  • \$\begingroup\$ Almost, except for the last line in your table. Take another look at exactly how the carry output is generated. \$\endgroup\$ – Dave Tweed Feb 5 '17 at 16:21
  • \$\begingroup\$ @DaveTweed I can't seem to figure out whats wrong. \$\endgroup\$ – user3472448 Feb 5 '17 at 16:49
  • \$\begingroup\$ And, your table only has 9 states. This counter counts from 0000 to 1111 -- sixteen states. Your table doesn't show Count Enable. While we are assuming it is 1, this should be shown, or at least specified. \$\endgroup\$ – Paul Elliott Feb 5 '17 at 16:52
  • \$\begingroup\$ Look at the Present State in that last line (of your original table). Why did you assign the value 1 to Output Carry? Also, if you want to add more information, use the edit button below your question. The answer area is reserved for answers. \$\endgroup\$ – Dave Tweed Feb 5 '17 at 16:58
  • \$\begingroup\$ Is your new chart showing next state for B0-B3? Not correct, but closer. You have skipped some states after 11 (1011). Also, look at Carry Out. This is the AND of Count Enable and Q0, Q1, Q2, Q3. \$\endgroup\$ – Paul Elliott Feb 5 '17 at 17:10
