1. The problem statement, all variables and given/known data Begin the design of the multiplier by adding more detail to the block diagram. The parts available for your design are • D Flip-flops (74LS74A) • 1 4-bit Up/Down Counter (74LS169) • 1 4-to-1 MUX • 1 4-bit Adder (74LS283) • 2 4-bit Parallel Shift Registers (74LS194A) • Various NAND/AND/OR/NOT gates Basically need to design a 4 bit multiplier using these parts. The block diagram that is referred to is just showing how everything connects up. 2. Relevant equations n/a 3. The attempt at a solution My attempt is in a file below because I thought that would be the best way to show it. I know it said not to use pictures in the rules, but I think it's ok for this right? My screen print cut off the very bottom wire, so yeah I used paint to put it back in sorry about that. My basic problem here is The D flip-flop that goes into the shift register keeps outputting high impedance. I tested this using 1011 as the multiplicand and 0111 as the multiplier. I'm also designing this in Allegro Design Entry.
