Replying to sjoelund.se:

Are you actually allowed to output both a continuous-time and discrete-time expression for the same equation?

Spec 3.8.3 says:

For an equation expr1 = expr2 where neither expression is of base type Real, both expressions must be discrete-time expressions.

Exceptions are only made for records.

That's a really good remark. I changed the model a bit, so that the mode has a discrete change of c while the continues integration.

So I think you are right we need to handle that whole equation as discrete.
