Extended Data Fig. 6: Analysis of n-bit adder scalability.
We utilize the automated design tool to design 1- to 6- bit adders to understand the material scalability with increasing n-bits in the adder operation. Two plots illustrating the relationship between the quantity of bits in an n-bit adder operation and the quantity of (a) switches and (b) material unit cells for the Standard Sum of Product (SSoP) and the Quine–McCluskey Sum of Product (QMSoP) design methods. The top plots illustrate a log10 scale and the bottom plots illustrate a linear scale for the quantity of switches and unit cells. The QMSoP reduces the material size by 31% in the 2-bit adder and by 92% in the 6-bit adder.
