In a previous career I was interested in implementing state machines in hardware. One started with some kind of abstract specification, and figured out how to implement the machine with a bunch of and and or gates. For the last 30 years I have been almost exclusively interested in implementing the abstract specification in software rather than hardware - hence Software Automata. Except for the most trivial specifications the implementation of state machines is too hard to attempt without tool support. Hence Software Tools are the key to producing Software Automata.
And what is the connection between "Automaton" and "Automata"? Well the word is from the Greek, and is one of those rare words in the English language that form the plural in an irregular fashion. One of the more recent foreign words imported into English that really stumps the journalists is the word "taliban". What is the plural of taliban? There isn't one, taliban is the plural, the singular is talib - meaning an islamic scholar.
