Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
It should be noted that the embodiments of the present invention and the technical features of the embodiments may be combined with each other without conflict.
Expansion devices in a computer system may conform to bus standard specifications, for example PCIE devices conform to the PCIE specification (a high speed serial computer expansion bus standard). When the expansion device is initialized, the computer system reads information in the configuration space of the expansion device as an initialized value, such as a device identification number, a vendor identification number, a subsystem identification number and a subsystem vendor identification number, a maximum connection speed, a maximum connection bandwidth or a time delay. In most processor-based computer systems, the configuration information of the expansion device is stored in its own EEPROM, such as an X86 computer system.
Meanwhile, the expansion devices are designed and developed strictly according to certain standard specifications, and the configuration information acquisition of the expansion devices is generally universal in computer devices, computer management cards and compatibility tests.
Based on this, the method for simulating the expansion device according to the embodiment of the present invention provides that, by obtaining part of configuration information on the existing expansion device, copying and writing the configuration information into the simulation card, and simulating the device with the same information based on the simulation card. The emulation card can be used for computer-side functionality testing or related testing related to the emulated expansion device.
Fig. 1 is a schematic diagram of the main steps of a method of simulating an expansion device according to an embodiment of the present invention. As shown in fig. 1, the method for simulating an expansion device according to the embodiment of the present invention mainly includes the following steps:
step S101: and acquiring configuration information of the expansion equipment.
Expansion devices refer to devices that employ some computer bus standards, such as PCIE devices, PCI devices, and ISA bus devices. Various types of tests for the expansion device are generally performed based on the configuration information thereof, such as compatibility tests, and based on this, when the expansion device is simulated, the configuration information thereof needs to be acquired. ISA is a bus standard established for PC/AT computers.
The configuration information may include: equipment identification number, manufacturer identification number, subsystem manufacturer identification number and the like.
Further, the configuration information may further include: capability device code, device state, device control, slot state, slot control, root state, root control, connection state, port number, reserved ports, advanced power management selection compatibility, connection state notification, data layer connection validation, reporting capability, unexpected shutdown and interrupt error reporting, clock power management, exit latency, advanced power management support, maximum connection speed or maximum connection bandwidth, and the like.
The expansion device follows a specific bus standard specification, the configuration information of the general structure is stored in the configuration space of the expansion device, and the configuration information can be acquired by analyzing or directly querying the storage file of the expansion device based on the characteristics of the expansion device. In the embodiment of the present invention, step S101 may be implemented by the following steps: and analyzing the storage file of the expansion equipment by using a logic chip of the analog card, or inquiring the storage file of the expansion equipment by using a viewing tool under a computer system to acquire the configuration information of the expansion equipment.

Step S102: and exporting the configuration file of the simulation card.
To reduce the dependence on actual expansion devices or the like and to reduce the consumption of expansion devices, devices with the same information can be simulated using a simulation card and used for functionality testing or related testing on the computer side in relation to the expansion devices, thereby reducing the repetitive installation or connection process and reducing the cost of development and testing. When the expansion device is simulated, the configuration file of the simulation card can be exported so as to write the information of the simulated expansion device.
In the embodiment of the present invention, step S102 may be implemented by the following steps: the configuration file of the memory of the emulation card is exported through the data interface of the emulation card or under the computer system.
The configuration file is stored in a memory of the analog card, which can be read and accessed via a data interface. The data interface is an interface for exporting or importing data on the analog card. Furthermore, if the emulation card is already connected to the computer system, data can be exported or imported directly under the computer system. The simulation card can be connected with a slot of a computer through a golden finger so as to be connected to the lower part of the computer system.
Step S103: the configuration file is edited based on the configuration information.
After the configuration file is generated, the configuration file of the simulation card can be edited according to the configuration information of the expansion equipment, so that the simulation card has the same information as the expansion equipment to replace the expansion equipment for testing, even information verification. It should be noted that, by editing the configuration file, the simulation card can simulate different expansion devices, so that the occupation of the expansion devices is significantly reduced, and the development and test costs are reduced.
Step S104: and importing the edited configuration file into the simulation card.
After the configuration file is edited, the configuration file is equal to the configuration information of the expansion equipment, and after the simulation card is imported, the simulation card has certain characteristics or specific indexes which are the same as those of the expansion equipment in a computer system or a test environment, so that the simulation of the expansion equipment is completed. The simulation card is used for replacing the expansion equipment to participate in computer-side tests, such as certain functionality tests; the edited configuration file is used to be read during the testing process.
When importing the edited configuration file into the emulation card, the same manner as that for exporting the configuration file can be adopted. In the embodiment of the present invention, step S104 may be implemented by the following steps: and importing the edited configuration file into a memory of the analog card through a data interface of the analog card or under a computer system.
According to the method for simulating the expansion equipment, the configuration information of the expansion equipment is acquired; exporting a configuration file of the simulation card; editing a configuration file based on the configuration information; the technical means of importing the edited configuration file into the simulation card overcomes the time and labor consumption of the test process; the situation of demand competition is easy to occur; the cost of development and testing is high; the technical problems that the requirements for verifying and displaying information cannot be met and the error probability is high are solved, so that the technical effects that equipment with the same information is simulated, repeated installation or connection processes during testing are reduced, requirement competition is avoided, and the development and testing cost and the error probability are reduced are achieved.
