You do know that idling starts disabled, right.  You have to explicitly enable it 
with a SET CPU IDLE command.  There are certain conditions when the 
SET CPU IDLE won't work.  

Presuming SET CPU IDLE doesn't work, I could give a better answer if you 
provided:
1) the output of SHOW VERSION at the sim> prompt
2) the output produced by make when you built one of these simulators.
and optionally:
3) The configuration file(s) you're using.
