Re: [Gems-users] Error while running

[Byn Choi <bynchoi1@xxxxxxxxxxxx>]

SimicsProcessor keeps a table of active requests for which it has  
issued the corresponding CacheMsg/s down through Sequencer::makeRequest 
(). The entries in this table are cleared when the Sequencer calls  
back the SimicsProcessor upon completion of performing that memory  
request. There are some sanity checks done at that time in  
SimicsProcessor, one of which is making sure that the size of the  
block that the operation was actually performed matches the original  
request size.
The error message is saying that check has failed. If you have changed  
the SLICC code, I'd say you used the wrong Sequencer::writeCallback or  
Sequencer::readCallback (depending on the access type) upon completing  
the request. Those functions are heavily overloaded and some have  
function signatures that carry the size information explicitly while  
others don't. I think -1 is inserted internally by the functions that  
don't take the explicit size parameter.
A good place to start to debug this is what the message suggested,  
attach a debugger to the process when you hit get to that point and  
examine the chain of call stacks that lead to this assertion failure.
