Txor = Tripple-(tpg+(Ngates-1)*Tao)
This formula uses 5 Variables
Variables Used
XOR Delay - (Measured in Second) - XOR Delay is the propagation delay of XOR gate.
Ripple Time - (Measured in Second) - Ripple Time of a carry-ripple adder circuit is defined as the time calculated of critical path delay.
Propagation Delay - (Measured in Second) - Propagation delay typically refers to the rise time or fall time in logic gates. This is the time it takes for a logic gate to change its output state based on a change in the input state.
Gates on Critical Path - Gates on Critical Path are defined as the total number of the logic gate required during one cycle time in CMOS.
AND-OR Gate Delay - (Measured in Second) - AND-OR Gate Delay in the gray cell is defined as the delay in the computing time in AND/OR gate when logic is passed through it.
STEP 1: Convert Input(s) to Base Unit
Ripple Time: 30 Nanosecond --> 3E-08 Second (Check conversion here)
Propagation Delay: 8.01 Nanosecond --> 8.01E-09 Second (Check conversion here)
Gates on Critical Path: 11 --> No Conversion Required
AND-OR Gate Delay: 2.05 Nanosecond --> 2.05E-09 Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Txor = Tripple-(tpg+(Ngates-1)*Tao) --> 3E-08-(8.01E-09+(11-1)*2.05E-09)
Evaluating ... ...
Txor = 1.49E-09
STEP 3: Convert Result to Output's Unit
1.49E-09 Second -->1.49 Nanosecond (Check conversion here)
FINAL ANSWER
1.49 Nanosecond <-- XOR Delay

What is latch up?

Latch-up pertains to a failure mechanism wherein a parasitic thyristor (such as a parasitic silicon controlled rectifier, or SCR) is inadvertently created within a circuit, causing a high amount of current to continuously flow through it once it is accidentally triggered or turned on. Depending on the circuits involved, the amount of current flow produced by this mechanism can be large enough to result in permanent destruction of the device due to electrical overstress(EOS).
