具体实施方式Detailed ways
为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。In order to make those skilled in the art better understand the solutions of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application.
低功耗供电系统对芯片设计和分析十分重要，性能越优的低功耗设计需要对芯片的硬件行为越了解，并结合软件做合理的电源分配和管理调度。目前，随着芯片规模越来越大，越来越复杂，一款芯片一般都会有超过数十、数百的供电域和供电控制单元，因此，芯片内部的供电信息的获取难度较大。目前，通用设计方案一般都是通过状态寄存器来读取芯片内部的供电信息，但是，这种通过寄存器状态读取的方式对芯片内部的供电信息分析了解十分有限。基本只能停留在静态的供电行为变化，对于动态的行为变化对应的功耗分析来说远远不能满足要求。因此，发明人发现，目前的供电信息的采集技术主要存在以下缺点：1、能力不足，可供检测的信号和数据十分有限。2、单一化，通过寄存器读取的供电信息对于分析的帮助十分有限。3、不灵活，可供读取的信息是固定的，不能任意选择。4、分析方式受限，读取的信息不能充分发挥软件的优势做详细可行的分析。The low-power power supply system is very important for chip design and analysis. A low-power design with better performance requires a better understanding of the hardware behavior of the chip, and reasonable power distribution and management scheduling in combination with software. At present, as the chip scale becomes larger and more complex, a chip generally has more than tens or hundreds of power supply domains and power supply control units. Therefore, it is difficult to obtain the power supply information inside the chip. At present, the general design scheme generally reads the power supply information inside the chip through the status register. However, this method of reading the state of the register has a very limited understanding of the analysis of the power supply information inside the chip. Basically, it can only stay in the static power supply behavior change, which is far from meeting the requirements for the power consumption analysis corresponding to the dynamic behavior change. Therefore, the inventor found that the current power supply information collection technology mainly has the following shortcomings: 1. The capability is insufficient, and the signals and data available for detection are very limited. 2. Simplification, the power supply information read through the register is of very limited help for analysis. 3. Inflexible, the information available for reading is fixed and cannot be selected arbitrarily. 4. The analysis method is limited, and the read information cannot give full play to the advantages of the software for detailed and feasible analysis.
针对上述问题，发明人经过长期的研究发现，并提出了本申请实施例提供的供电信息的采集方法、系统以及芯片，通过芯片的多路数据采集系统对芯片的多个待采集对象的供电信息进行采集，提升所采集的芯片的待采集对象的数量，以满足对芯片的供电及功耗的分析需求。其中，具体的供电信息的采集方法在后续的实施例中进行详细的说明。In view of the above problems, the inventor has discovered through long-term research, and proposed the method, system and chip for collecting power supply information provided by the embodiments of the present application, and the power supply information of multiple objects to be collected on the chip is collected through the multi-channel data collection system of the chip. The collection is performed to increase the number of objects to be collected in the collected chips, so as to meet the analysis requirements for the power supply and power consumption of the chips. The specific method for collecting the power supply information will be described in detail in the following embodiments.

其中，对芯片低功耗的分析，不仅仅需要知道芯片的各个待采集对象对应的供电信息，还需要知道各个待采集对象对应的供电信息的状态变化以及持续的时间，以便于更详细的分析来制定合理高效的软件控制。例如，除了知道某个待采集对象对应的供电信息，还需要知道某个待采集对象进入和退出休眠的时间点，或者，除了知道某个待采集对象对应的供电信息，还需要知道某个待采集对象高负荷持续运行的时间，或者，除了知道某个待采集对象对应的供电信息，还需要知道某个子系统闲置的时间等。因此，在本实施例中，可以通过时间计数器120来进行统计。Among them, the analysis of the low power consumption of the chip not only needs to know the power supply information corresponding to each object to be collected on the chip, but also needs to know the state change and duration of the power supply information corresponding to each object to be collected, so as to facilitate more detailed analysis. To develop reasonable and efficient software control. For example, in addition to knowing the power supply information corresponding to an object to be collected, it is also necessary to know the time points when an object to be collected enters and exits dormancy. The time that the collection object continues to run under high load, or, in addition to knowing the power supply information corresponding to a certain object to be collected, it is also necessary to know the idle time of a certain subsystem. Therefore, in this embodiment, statistics can be performed by the

The method for collecting power supply information is used to collect the power supply information of multiple objects to be collected on the chip through the multi-channel data collection system of the chip, so as to increase the number of objects to be collected on the collected chip, so as to meet the requirements of power supply and Analysis of power consumption needs. In a specific embodiment, the power supply information collection method is applied to a chip power supply information collection system, wherein the power supply information collection system includes a multi-channel data collection system, and the multi-channel data collection system consists of at least one multi-channel data collection system. selector composition. The flow shown in FIG. 5 will be described in detail below. The method for collecting power supply information may specifically include the following steps:
步骤S110：获取所述芯片上的多个待采集对象。Step S110: Acquire multiple objects to be collected on the chip.
在本实施例中，芯片上的多个待采集对象可以是系统默认设置的，也可以是用户手动设置的，并且，芯片上的多个待采集对象可以是固定的，也可以是可变的，在此不做限定。在一些实施方式中，多个待采集对象可以包括供电控制信号、供电状态信号、各类状态机状态值、系统片上电压、电流检测数据、各个子系统工作状态、异常保护及请求信号中的一种或几种的组合。其中，不同的芯片对应的待采集对象可以相同，也可以不相同。In this embodiment, the multiple objects to be collected on the chip may be set by default by the system or manually set by the user, and the multiple objects to be collected on the chip may be fixed or variable , which is not limited here. In some embodiments, the multiple objects to be collected may include one of power supply control signals, power supply status signals, various state machine status values, system on-chip voltage, current detection data, working status of each subsystem, abnormal protection and request signals one or a combination of several. The objects to be collected corresponding to different chips may be the same or different.
例如，当不同的芯片对应的待采集对象相同时，可以认为芯片1、芯片2……芯片N对应的待采集对象均包括待采集对象1、待采集对象2、待采集对象3、待采集对象4以及待采集对象5。那么，在获取待分析的芯片后，由于每个芯片对应的待采集对象相同，则可以直接确定该待分析的芯片上的多个待采集对象包括：待采集对象1、待采集对象2、待采集对象3、待采集对象4以及待采集对象5。For example, when the objects to be collected corresponding to different chips are the same, it can be considered that the objects to be collected corresponding to chip 1, chip 2, ... chip N all include the object to be collected 1, the object to be collected 2, the object to be collected 3, the object to be collected 4 and the object to be collected 5. Then, after acquiring the chip to be analyzed, since the objects to be collected corresponding to each chip are the same, it can be directly determined that the multiple objects to be collected on the chip to be analyzed include: object to be collected 1, object to be collected 2, object to be collected Collection object 3 , to-be-collected object 4 , and to-be-collected object 5 .
又例如，当不同的芯片对应的待采集对象不相同时，可以认为芯片1、芯片2……芯片N均有各自对应的待采集对象，如芯片1对应的待采集对象包括待采集对象1、待采集对象2、待采集对象3，芯片2对应的待采集对象包括待采集对象2、待采集对象3、待采集对象2。那么，在获取待分析的芯片后，由于每个芯片对应的待采集对象可能不同，则可以先对待分析的芯片进行识别，再根据识别结果获取该待分析的芯片对应的待采集对象，如识别结果表征待分析的芯片为芯片1时，可以获取该待分析的芯片对应的待采集对象包括待采集对象1、待采集对象2、待采集对象3。For another example, when the objects to be collected corresponding to different chips are not the same, it can be considered that chip 1, chip 2... and chip N have their own corresponding objects to be collected. For example, the objects to be collected corresponding to chip 1 include Object to be collected 2 , object to be collected 3 , and the object to be collected corresponding to chip 2 includes object to be collected 2 , object to be collected 3 , and object to be collected 2 . Then, after obtaining the chips to be analyzed, since the objects to be collected corresponding to each chip may be different, the chips to be analyzed can be identified first, and then the objects to be collected corresponding to the chips to be analyzed can be obtained according to the identification results. The result indicates that when the chip to be analyzed is chip 1, the to-be-collected objects corresponding to the to-be-analyzed chip can be obtained, including to-be-collected object 1, to-be-collected object 2, and to-be-collected object 3.
步骤S120：将所述多路数据采集系统和所述多个待采集对象连接。Step S120: Connect the multi-channel data collection system to the multiple objects to be collected.

In some embodiments, the multi-channel data acquisition system consists of at least one multiplexer, and after acquiring multiple objects to be collected, the at least one multiplexer can be connected to the multiple objects to be collected, wherein all the The number of multiplexers used can be determined according to the number of objects to be collected. Generally, the greater the number of objects to be collected, the greater the number of multiplexers used, and the less the number of objects to be collected. Fewer multiplexers are used.
在一些实施方式中，该多路选择器可以使用256选16的设计，或者使用256选32的设计。In some embodiments, the multiplexer may use a 256-to-16 design, or a 256-to-32 design.
步骤S130：通过所述多路数据采集系统采集所述多个待采集对象对应的供电信息。Step S130: Collect power supply information corresponding to the multiple objects to be collected through the multi-channel data collection system.
在本实施例中，在将多路数据采集系统和多个待采集对象连接后，可以通过多路数据采集系统采集多个待采集对象对应的供电信息。其中，多路数据采集系统可以从多个数据信号中选择出若干输出信号，即，多路数据采集系统可以采集包括多个待采集对象对应的供电信息在内的多个信息，并从多个信息中选择输出多个待采集对象对应的供电信息，从而实现提升采集的供电信息的数量，满足对芯片的供电及功耗的分析需求。In this embodiment, after the multi-channel data acquisition system is connected to the multiple objects to be collected, the power supply information corresponding to the multiple objects to be collected can be collected through the multi-channel data acquisition system. Among them, the multi-channel data acquisition system can select a number of output signals from a plurality of data signals, that is, the multi-channel data acquisition system can collect a plurality of information including power supply information corresponding to a plurality of objects to be collected, and select a plurality of output signals from a plurality of data signals.
