Hi, Andreas ! Actually, while running some benchmarks in full system mode, I observed some differences in total number of committed instructions on detailed and functional mode. It seems like the execution path is not the same in both cases and I am not sure of the reasons. So, I generate BBV on detailed mode, so that I can later use them in detailed mode simulation.
But, I tried to compare detailed mode BBV profile with atomic mode BBV profile (in this case, the benchmark is run on system emulation mode and there is no difference in number of instructions committed in both cases). Surprisingly the genrated BBV profiles are not same. As the BBV generation code that I use with detailed mode cpu is same as in atomic mode (with minor modifications), so I am not sure what's going wrong here !
