O.k., thanks for clearing things up. So MyHDL is very valuable for me 
for describing
the connection from the wire into the AVR via UART, Port or USI (simple 
shiftregister
base serial communication hardware) and simulating a 1-wire network 
based on that.

For the final coding however I'll have to derive C manually. It's o.k. 
this way, I just did not
want to spend time on things that would be to difficult to achieve. But 
MyHDL is still useful
here too because of the easy simulation of modification to the algorithms.
