Design, Layout and Simulation of 8 bit Arithmetic and Logic Circuits Pad frame using C5 Process for deep submicron CMOS

A critical component of the microprocessor, the core component of central processing unit. Arithmetic and logic circuits comprises the combinational logic that implements logic operations such as AND and OR, and arithmetic operations such as Addition, Subtraction, and Multiplication. In this presented work, an 8-bit arithmetic logic circuit is designed, implemented and simulated using the Electric CAD and SPICE software. The proposed design is an 8-bit arithmetic and logic circuit that can perform: A AND B, A OR B, A + B (addition), and A - B (subtraction) and all possible arithmetic and Logical operations. Physical design of every sub module is carried out using C5 process 300 nm process technology. A pad frame is also designed and subsequent Design Rule Checks and network consistency checks are performed on the same.
