Consider a circuit with three paths: path A has a delay of 10 ns, path B has a delay of 12 ns, and path C has a delay of 8 ns. If retiming moves a flip-flop from path B to path A, what is the potential new delay for path A, assuming both paths are balanced after retiming?
💡 Hint: Think about the effects of shifting flip-flops on path delays.
You are designing a circuit requiring a clock frequency of 200 MHz, but your retiming analysis indicates a critical path delay of 6 ns. After retiming, you achieve a delay of 4 ns. What is the new clock frequency, and does it meet the design requirement?
💡 Hint: Use the formula for frequency and consider how retiming improves delays.
