Critical Path Delay in CMOS Design and Applications Formulas

The critical path delay is the sum of the delays of the shifter, the conditional complementer (for the subtraction), the adder, and the register. And is denoted by T_delay. Critical Path Delay is usually measured using the Nanosecond for Time. Note that the value of Critical Path Delay is always positive.

FAQ

What is the Critical Path Delay?

The critical path delay is the sum of the delays of the shifter, the conditional complementer (for the subtraction), the adder, and the register. Critical Path Delay is usually measured using the Nanosecond for Time. Note that the value of Critical Path Delay is always positive.

Can the Critical Path Delay be negative?

No, the Critical Path Delay, measured in Time cannot be negative.

What unit is used to measure Critical Path Delay?

Critical Path Delay is usually measured using the Nanosecond[ns] for Time. Second[ns], Millisecond[ns], Microsecond[ns] are the few other units in which Critical Path Delay can be measured.
