In this way an access to those register won't make simulation fail.

The power interface is defined so it can interact with thermal models as well. It implements a simple power evaluator that can be used for simple power models that express power in the form of a math expression. These expressions can use stats within the same SimObject (or down its hierarchy) and some magic variables such as "temp" for temperature. In future patches we will extend this functionality to allow slightly more complex expressions. The model allows it to be extended to use other kinds of models. Finally, the thermal model is updated to use the power usage as input. |

Each clock domain is required to be associated with a voltage domain, and the latter requires the voltage to be explicitly set. A voltage domain is an independently controllable voltage supply being provided to section of the design. Thus, if you wish to perform dynamic voltage scaling on a CPU, its clock domain should be associated with a separate voltage domain. The current implementation of the voltage domain does not take into consideration cases where there are derived voltage domains running at ratio of native voltage domains, as with the case where there can be on-chip buck/boost (charge pumps) voltage regulation logic. The regression and configuration scripts are updated with a generic voltage domain for the system, and one for the CPUs. |

H A D | kernel.cc | 13077:0037323cb4dd Wed Aug 22 20:52:00 EDT 2018 Gabe Black <gabeblack@google.com> systemc: If sc_main returns, don't do any more systemc stuff. When sc_main returns, clear out any pending work in the scheduler and also block the systemc kernel from doing actions which correspond with the start of simulation. It's most likely that work like oustanding timeouts might survive past the end of sc_main, especially if it never officially called sc_stop. It's also possible for sc_main to return and never actually call sc_start. In that case, the kernel should not call callbacks of the various objects (which may no longer even exist), or go through the initialization phase. If sc_main is never called at all, then the kernel's actions aren't gated.

For example, it is only the CPU-side port that blocks incoming requests, and only the memory-side port that schedules send events outside of what the transmit list dictates. This patch simplifies the two classes by relying further on SimpleTimingPort and also generalises the latter to better accommodate the changes (introducing trySendTiming and scheduleSend). The memory-side cache port overrides sendDeferredPacket to be able to not only send responses from the transmit list, but also send requests based on the MSHRs. A follow on patch further simplifies the SimpleTimingPort and the cache ports. |
