CMOS Logic Operation Simulator

The Static CMOS Circuit Wizard

The "Static CMOS Circuit Wizard" is an educational Java applet designed to complement teaching of VLSI design courses. It has been designed as a senior design project at the Computer Engineering Department of King Fahd University of Petroleum and Minerals , Dhahran, Saudi Arabia. The applet is meant to support teaching of the COE 360 course, "Principles of VLSI Design" offered by the Computer Engineering Department.

When provided with a logical function, the applet displays the transistor-level static CMOS implementation of that function. The output state is color-coded. A logic 0 is coded as black, while a logic 1 is coded as red. Enabled paths to the output node are also indicated on the schematic using the same color code.

The state of any input variable can be toggled by clicking on the corresponding terminal.

An applet should be running here..

Instructions:

Functions should be written as: F = FUNCTION, where F is the output variable and FUNCTION is any Boolean expression.
Variable names can be any alphabet character. The applet is case-insensitive (a is similar to A).
Variable names can be numbered, e.g. A1 or B5 (digits must immediately follow the alphabet character with no white space).
An OR operation is represented by a (+) sign, while an AND operation can be represented by either ( * ), ( . ), or white space.
The complement is represented by the ( ' ) sign immediately following a variable.
Parenthesized expressions are allowed.
Complement of parenthesized expressions is not allowed, e.g. (A + B)' should be written as (A' * B').
