LTSpice State Machines README

This extension offers textual Highlights of LTSpice State Machines Also suggests common Snippets of the various State Machine elements

LTspice XVII includes an arbitrary state machine and introduces a new programming language called Contraption Programming Language. There are five commands:

   .mach[ine] [<tripdt>] ; tripdt is an optional temporal tolerance
   .state <name> <value>
   .rule <old state> <new state> <condition>
   .output (node) <expression>
   .endmach[ine] ; end of block
