[Haskell-cafe] ANN: atom-0.0.2

[Tom Hawkins]

Atom is a DSL in Haskell for designed hard realtime embedded programs.
At Eaton, we are using it to control hydraulic hybrid refuse trucks
and shuttle buses. After my talk at CUFP
(http://cufp.galois.com/2008/schedule.html), a few people inquired
about atom -- I finally had a chance to upload it to Hackage.

http://hackage.haskell.org/cgi-bin/hackage-scripts/package/atom-0.0.2

Some new enhancements:
- A simple rule scheduler for load balancing.
- Signal probing for debug and data logging.
- Functional coverage to monitor which rules have executed.
- Started integration with the Yices SMT solver for bounded model checking.

Experiences with our Eaton project:
- 5K lines of Haskell/atom replaced 120K lines of matlab, simulink,
and visual basic.
- 2 months to port simulink design to atom.
- 3K lines of atom generates 22K lines of embedded C.
- Design composed of 450 atomic state transition rules.
- Rules with execution periods from 1ms to 10s all scheduled at
compile time to a 1 ms main loop.
- 3 minute compilation time from atom source to ECU.
- Atom design clears electronic/sw testing on first pass.
- Currently in vehicle testing with no major issues.

Congratulations on the release!

If any one has been looking at this and wants another example, I've finished two posts on the topic of Atom.

These posts depend on a patch: http://code.sw17ch.com/blog/atom/atom_0.0.2_sw17ch_1.diff

Part 1: http://blog.sw17ch.com/wordpress/?p=84 <- Brief discussion and describes the patch
Part 2: http://blog.sw17ch.com/wordpress/?p=111 <- Writing a program to blink an LED.

Feed back would be appreciated!
