Can you provide a little more information?
How many fundamental variables do you need? ....ABCDEF?
Are you using flip-flops .... what kind?
... Not sure what you mean by 2 present and next states.
i have 6 inputs,3 outputs...and 4 states which can be represented by 2 bits.. so i think it will be an 8 variable k-map...for each of the 3 o/ps and 2 variables representing next state..
Is there any easy method to get the boolean expressions,,,or do i have to make an 8 variable k-map....??
INPUTS PRESENT NEXT OUTPUTS
STATE STATE
m e a b c d P1 P0 P1* P0* u d s
INPUTS--------PRESENT-----NEXT---OUTPUTS
---------------STATE-------STATE
====================================
m e a b c d.......P1 P0..........P1* P0*....u d s
I am trying to classify your objective .... as to what kind of standard problem it is.
Would you describe it as a non-sequential counter? .... That is, you have a group of variables, and with each clock pulse, the variable group changes in value, going to the next subsequent state.
For example, 000001 .... 001110 ....111000 ... and so on, changing with each clock pulse.
