[Gems-users] Invalid transition in MOESI_CMP_directory protocol

[Enric Herrero <enricherrero@xxxxxxxx>]

Hi,

We have tested the MOESI_CMP_Directory Protocol with
tester.exec and it seems to have a problem with a
invalid transition as we can see in the debug file:

Warning: in fn TransitionResult
L2Cache_Controller::doTransitionWorker(L2Cache_Event,
L2Cache_State, L2Cache_State&, const Address&) in
generated/MOESI_CMP_directory/L2Cache_Transitions.C:2067:

L2Cache_Controller::doTransitionWorker(L2Cache_Event,

Invalid transition

It seems that there's no transition from ILOX for the
L1_PUTX event.  It's  suposed to stay in the same
state and recycle the request queue or it has to
change to ILOXW?

Thanks

Marco and Enric
