Re: [Gems-users] Transactional Memory

[mishali <mishali@xxxxxxxxxxx>]

I found the problem, by mistake I was calling set_transaction_registers()
before I start simulation (so ruby is not attached). I moved the call
inside the section which I am simulating and that fixed the problem. 

thanks a lot for your help!
