Does anyone have resources that talk about writing a TLA+ model for an existing software system as opposed to designing a new system using TLA+ as the design reference?

Below are a few specs related to refactoring/rewriting the TLA+ model checker to scale to more cores:

* https://github.com/tlaplus/tlaplus/blob/master/tlatools/src/...

* https://github.com/tlaplus/tlaplus/blob/master/tlatools/src/...

Check out Marianne Bellotti's work. She recently gave a talk at Strange Loop on writing specifications of existing systems: https://www.youtube.com/watch?v=oMSmkRGzQ64
