Formal Axiomatic Specification in Alloy

We present a formal specification of the RVWMO memory model in Alloy (http://alloy.mit.edu). This model is available online at https://github.com/daniellustig/riscv-memory-model.

The online material also contains some litmus tests and some examples of how Alloy can be used to model check some of the mappings in Section [sec:memory:porting].
