Design Spec Refinement Proof

This proof establishes that seL4's design specification is a formal refinement (i.e. a correct implementation) of its abstract specification. This proof also interweaves the definition and proofs of the global invariant for the design specification, and builds on the Abstract Spec Invariant Proof. It is described in the TPHOLS '08 paper.

Building

To build from the l4v/ directory, run:

./isabelle/bin/isabelle build -d . -v -b Refine

Important Theories

The top-level theory where the refinement statement is established over the entire kernel is Refine; the state-relation that relates the state-spaces of the two specifications is defined in StateRelation and the basic correspondence property proved over each kernel function is defined in Corres.
