Ok, trying to design a relatively simple logic circuit with 3 inputs and 3 outputs. (A, B, C and a, b, c) When A is high, a is high and all the rest are low. Then when B goes high a drops out and b goes high even if A is still high. If C goes high, c is high and both a and b are low even if A and B are high. I've tried experimenting with various latches and other combinations. Just when I think I'm getting close I get oscillation issues. Any ideas or help would be great.
