Patent US 8,522,221

A method and system for the automatic generation of user guides. Specifically, the method of the present invention includes accessing an abstract processor model of a processor, wherein said abstract processor model is represented using a hierarchical architecture description language (ADL). The abstract processor model includes a plurality of instructions arranged in a hierarchical structure. An internal representation of the abstract processor model is generated by flattening the abstract processor model. The flattening process generates a plurality of rules grouped by common convergent instructions. Each rule describes an instruction path through the hierarchical structure that converges at a corresponding convergent instruction. An instruction-set documentation is automatically generated from the plurality of rules, wherein the instruction-set documentation is arranged convergent instruction by convergent instruction.
