Embodiments of the present application provide a fault analysis data storage method, a fault analysis method, a device and a storage medium. The method comprises: by an electronic device running a real-time operating system, every interval of a preset time length, obtaining first identification information of a task executed by the electronic device based on the real-time operating system at the current time, and storing the first identification information, updating the cumulative running number of a plurality of tasks within a statistical time according to the first identification information, and storing the updated cumulative running number, when the electronic device has a task timeout not executed, generating a data file comprising the stored first identification information and the cumulative running number, and storing the data file in the non-volatile storage unit of the electronic device, providing analysis data for subsequent fault analysis and positioning.

Examples described herein provide a computer-implemented method that includes receiving a circuit design and a set of known process, voltage, and temperature (PVT) points for components of the circuit design. The method further includes determining parameter ratios for the set of known PVT points. The method further includes performing a statistical static timing analysis on the circuit design using the set of known PVT points and at least one additional PVT point generated during the statistical static timing analysis. The method further includes performing projections and root sum squaring for possible corners in a parameter space based on a canonical model generated during performing the statistical static timing analysis.

A contract rate intelligent calculation method, apparatus and device, and a medium, the method comprising: receiving a contract settlement rule configured by a user, the contract settlement rule comprising data source information, a statistical time range, a calculation period and a rate calculation formula; according to the data source information and the statistical time range, order data is pulled from a corresponding data source; dividing the order data according to the calculation period to generate corresponding calculation units; and executing the rate calculation formula to calculate the order data in each calculation unit to obtain the contract rate in the corresponding calculation period, thereby realizing automatic and intelligent rate settlement work, greatly improving the calculation efficiency and accuracy, and being capable of flexibly adapting to complex and changeable business rules.

The invention provides an IOT data processing method and electronic equipment. The method is applied to a communication system comprising a terminal, IOT equipment and a cloud. The method comprises the following steps that: a cloud periodically acquires a to-be-processed task, wherein the type of the to-be-processed task can be sampling, statistics or re-statistics; and if the task to be processed is a sampling task, locking the sampling task by adopting a distributed lock, normalizing the sampling time, and collecting and storing the IOT data when the sampling time is reached. If the to-be-processed task is a statistical task, locking the statistical task by adopting a distributed lock, normalizing statistical time, judging whether a preorder task of the statistical task is completed or not when the statistical time is up, and if so, counting and storing IOT data; otherwise, executing the re-statistics task. And if the to-be-processed task is a re-statistics task, locking the re-statistics task by adopting a distributed lock, normalizing the re-statistics time, and counting and storing the IOT data when the re-statistics time is reached. And finally, the cloud sends the stored data to the terminal for display.
