That stuff gets rediscovered all the time, the latest example probably being golang

I've always thought CSP as a robust design pattern where you have no shared state between components and they must communicate with each other using message passing. It also requires synchronous communication (rendezvous-style). If you follow those rules you can have a pretty robust system. Aside from these abstract rules, CSP has more formal research (algebra) but I'm not sure if there are any decent tools available.

TLA gives you a full toolbox and in theory can model whatever you can express. That's very different from a design pattern.

I am learning TLA+ but I do not know CSP, is CSP better?

Nah, jump straight to pi-calculus.

Hahaha this is so funny... people here get slammed all the time of using AI for writing and here be, just someone writing his way through Internet history and gets slammed for it just the same... you can't hardly win with an audience like this... haha

Real world applications of TLA+: https://foundation.tlapl.us/industry/index.html.

The Intel paper shows how TLA+ was applied as a step prior to writing the hardware description. I'm not sure if it caught on, it seems like other tools are used nowdays, does anyone here in the VLSI industry know?

Took 10 minutes to find this: TLA+ is a formal specification language developed to design, model, document, and verify reactive systems.
