Yes, Synthesis server don't generate progress events. so it depends on stepCmd in the doSync(). I want to add a new virtual function 'void reportStepCmd(sysync::uInt16 stepCmd)' in the SyncContext. It is called in the loop at the end of each step command . Session in dbus server receives this stepCmd info and set its status.
