According to EASA simulator time is purely ground duty and doesn't count into block time totals. It is still duty time, but not FDP. And as there is no flying being done, just ground duty, there are no sectors to count either.
This stems from the idea that EASA prescribes only a minimum level of flight safety. As long as the rest time before starting the next flight duty is sufficient, everything is OK. They do not care about what happens during ground duty at all.
Your CLA might see things differently though. In my outfit simulator time is counted as block time (the full amount of scheduled time in the simulator, including pre-simulator briefing time), there is no sector count however and the usual pre-flight duty rest rest requirements apply, unlike for a pure ground duty.
