Summary
Puff is a circuit simulator for linear circuits. It calculates scattering parameters and makes microstrip and stripline layouts. It also makes time-domain plots. The program is named after the magic dragon in the song by the popular American singing group Peter, Paul and Mary. Puff originated as a teaching tool for Caltech's microwave circuits course. It was created as an inexpensive and simple-to-use alternative to professional software whose high costs, copy protection schemes, and training requirements create difficulties in the academic environment. Puff uses a simple interactive schematic-capture type environment. After a circuit is laid out on the screen using cursor keys, a frequency or time domain analysis is available with a few keystrokes. This process is faster than using net lists, and errors are rare since the circuit is always visible on the screen. Intended for students and researchers, public distribution of the program began in 1987. Puff use, originally limited to Caltech, UCLA, and Cornell, has since spread to many other universities and colleges. The program has also become popular with working engineers, scientists, and amateur radio operators. Over 20,000 copies of versions 1.0, 1.5, 2.0, and 2.1 have been distributed worldwide, and translations have been made to Russian, Polish, and Japanese.
