How to Calculate Tree Adder Delay?
Tree Adder Delay calculator uses tree_adder_delay = propagation delay+log2(n-input AND gate)*Delay of the AND-OR gate+xor delay to calculate the Tree Adder Delay, The Tree Adder Delay formula is defined as This comes at the cost of many long wires that must be routed between stages. The tree also contains more PG cells; while this may not impact the area if the adder layout is on a regular grid, it will increase power consumption. Despite these costs, the Kogge-Stone tree is widely used in high-performance 32-bit and 64-bit adders.In summary, a Sklansky or Kogge-Stone tree adder reduces the critical path. Tree Adder Delay and is denoted by Ttree symbol.
How to calculate Tree Adder Delay using this online calculator? To use this online calculator for Tree Adder Delay, enter propagation delay (τ), n-input AND gate (n), Delay of the AND-OR gate (tAO) and xor delay (Txor) and hit the calculate button. Here is how the Tree Adder Delay calculation can be explained with given input values -> 33 = 20+log2(2)*5+8.
