At some point, I had been working with UML, and wanted to do so, but never did it, I do not think anyone else plans it, because we have other solutions for simuation: - a discrete event simulator called xeno-sim, which has unfortunately become largely unused, so, may be hard to get running for a newcomer; - running a normal kernel inside qemu, some people actually debug Xenomai this way. - if using the posix skin, you can compile your applications as simple linux applications. The advantage of using UML over the other solutions is that you could develop and validate drivers, whereas you have to write some simulation code (simulating the hardware which driver you are developing) for the other solutions.
