The first thing to remember is that a BCD digit is only 4 bits (a nibble).
Secondly BCD is a base 10 system so the largest number for each digit is 9 but a nibble can have a value of up to 15.
Thirdly, after each addition the resulting value has to be normalized. Here is the rule. If the resulting value is grater than 9, subtract 10 and also carry 1.
Programming this is your job.
BCD can be converted into 7segment display by using an encoder.
The count sequence of a BCD down counter is as follows: 1001,1000,0111,0110,0101,0100,0011,0010,0001,0000,1001. . . . . . .
the first time write the binary coded decimal as input write its truth tablle to nine and after nine put the all position dont care to number fifteen same is also for excess three write its truth table to 9 and from 9 to 15 dont care then simplifiy each output coloumn by K_MAp to find out th circiut

All possible 2-bit numbers ... 0, 1, 2, and 3 ... are the same in BCD and binary. No conversion is required.
The name BCD doesn't stand for anything according to Bernd Rittinger, BCD Travel Director of Operations.
