  Simpogical is a mobile application for quickly simplifying digital logic circuits
Keywords: Karnaugh Map, Quine McCluskey, Boolean Algebra and Petrick's Method

Karnaugh Maps are great, but they are far from ideal for problems with more than 4 variables. An alternative is to use a tabular method, such as the Quine McCluskey Algorithm. However, using pen and paper this is slow, tedious and error prone. The idea behind Simpogical is to give you a logic simplification tool that sits right on your phone.


Simpogical was developed  for use by students studying Electronic Engineering. Under the hood, it uses the Quine-McCluskey algorithm to perform the simplification and, where required, Petrick's method to provide a list of  permutations. Results are equivalent to Karnaugh Mapping.

The idea for the application came from teaching Boolean logic simplification to stage-1 undergraduates at the University of Plymouth (UK). Performing these calculations by hand is both tedious and error prone. The iPhone / iPod Touch seemed to be the ideal platform for a pocket application (I even use it to check my worked examples during Lecutures).

Simpogical is written as a "Universal" application (also runs on an iPad in native resolution).

How to obtain Simpogical

Simpogical is a Universal iPhone / iPod Touch / iPad application only available from the Apple iPhone Application Store.
