Hi Martin,

In the past I've tested both simulation drivers to make sure they have the same behavior (although, with a limited set of tests). I would use the new phase-3 driver when ever possible. However, if you are using phase-2 drivers it would make sense to use the phase-2 simulation if you are concerned about changes in behavior.

The phase-3 drivers inherit from the asymMotorController base class, which in-turn inherits from asynPortDriver. So a quick look at the source code can tell you what kind of driver it is. Also, the phase-3 drivers tend to have IOC shell functions that look something like this:

createMyController(..)
createMyAxis(1)
createMyAxis(2)
etc.

with a separate function to instantiate the controller object, then either a function to create a single axis or a set of axes for that controller object.

I'm also using R6-8 here.

If you send me a tar file of your IOC, I'll build it here and see if I can reproduce it.

Maybe a detailed Asyn trace would also help.

Cheers,
Matt
