Abstract
The invention discloses a design method for testing BIT in server equipment. A server is divided into two layers of a module level site replaceable unit (LRU) and a chip level functional circuit according to a complete machine and a unit in the aspect of a system structure, and each functional unit can perform testing independently; the functional units of the server are mainly connected through a network cable, and the voltage, the temperature and the work state of the units can be monitored and managed through a management unit. The method is divided into three steps of distributed type testing and acquisition management, information state concentrated processing, and display and operation according to a framework structure. The design method has high fault diagnosis capacity and can isolate faults to the units (LRU); full testing can be performed, equipment reliability and safety are guaranteed by testing all possible faults of a covered equipment circuit system, and equipment reliability and testability are greatly improved.
Description
Technical field
The present invention relates to and reinforce server and technical field of measurement and test, be specifically related to a kind of server apparatus built-in test BIT method for designing, devise a kind of built-in test method for designing of server, substantially increase reliability and the testability of equipment.
Background technology
In server application, high reliability request airborne equipment, on-board equipment, mobile unit, as satellite, airship and naval ship, do not allow to break down.In order to ensure the reliability of equipment and system, generally all require that equipment has higher trouble diagnosibility, and can by fault isolation to each unit (LRU); And can fully test, reliability and the security of equipment is guaranteed by all contingent faults of Test coverage circuitry system.
In order to realize above-mentioned technical requirement, server must be carried out distinguishing hierarchy and design from system architecture, function two aspect to testability design, just consider the demand of test performance at the beginning of design comprehensively, by stratification detection and the fault isolation of chip-scale BIT, module level BIT and System-Level BIT, improve the reliability of equipment.
Built-in test BIT(Built-InTest) be a kind of important technology that can significantly improve system testing and diagnosis capability, be one of important technical realizing Testability Design.Describe the definition of built-in test technology, feature, classification, design content and design cycle etc., illustrate the development course of built-in test technology, and the new trend of testability technology is inquired into and looked forward to.
BIT refers to the automatic test capability of detection that system and device interior provide, isolated fault, refer to that system headrig just can complete functional check to system, subsystem or equipment, fault diagnosis and treatment and performance test without external test facility, it is the new development of On-line measurement technology.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of magnetic-type wicket, can meet EMC Requirements, and simultaneously simple and reliable for structure, processing cost is low, installs also more for convenience.
Ruggedized computer wicket is usually after wicket is closed, requirement can keep certain snap-in force to the shielding material playing sealing and electromagnetic screen, this snap-in force makes encapsulant generation elastic deformation, thus fill surface of contact gap, play the effect of sealing (waterproof) and conduction continuous (electromagnetic compatibility).
The technical solution adopted in the present invention is:
A kind of server apparatus built-in test BIT method for designing, described server is two levels according to complete machine and dividing elements in system architecture: module level Field Replaceable Unit LRU and chip-scale functional circuit, and each functional unit can independently be tested; Connect mainly through network cable between each functional unit of server, by administrative unit, monitor and managment is carried out to the voltage of each unit, temperature and duty thereof;
Described method is divided into three grades by framed structure: distributed testing and acquisition process, information state focus on, show and operate, and implementation procedure is as follows:
The first order, distributed testing and acquisition process: by self-test and Acquisition Circuit, directly embed in each unit (LRU) and realize;
The second level, information state focus on, by the acquisition process circuit of complete machine, administrative unit is by the status information such as management bus (mode such as network, serial ports) Real-time Collection self-test and the temperature measured by acquisition process circuit, voltage, Key Circuit test point characteristic signal;
The third level, display and operation: the information state of complete machine is undertaken showing and processing by the aobvious control terminal be inlaid in administrative unit; And the state of complete machine is externally issued by supervising the network.
Described first order distributed testing and acquisition process process, self-test and Acquisition Circuit, the each unit of direct embedding (LRU), built-in test BIT circuit reads each functional circuit sensor information by IPMB, carry out TDI input by chip JTAG mouth and TDO is compared with the standard value of write register, judge that whether chip is normal, fault alarm, fault diagnosis and fault handling function are provided, thus improve unit reliability;
Wherein: IPMBIntelligentPlatformManagementBUS, Intelligent Platform Management Bus is the general name of two groups of redundancy I2C buses of each FRU backboard communication of the telecommunications computing platform that ATCA (AdvancedTelecomComputingArchitecture) is advanced;
The chip with JTAG mouth has following JTAG pinout:
TCK---test clock inputs;
TDI---test data inputs, and data input JTAG mouth by TDI;
TDO---test data exports, and data are exported from JTAG mouth by TDO;
TMS---test pattern is selected, and TMS is used for arranging JTAG mouth and is in certain specific test pattern.
Described method test process adopts the mechanism of continuous monitoring, continuous detecting in systems in which.Some fault may not influential system work, automatically disappears sometimes, although and some faults can not damage equipment, if stopped not in time, system can cannot normally work, and therefore need to take immediate measure, otherwise fault is by damage equipment.
Described method is when realizing fault detection capability, and for each detection module designs a failure counter, Counter Value is initialized as 0, and when functional module detects primary fault, failure counter adds 1.Enter next sense cycle, if failure vanishes, then failure counter subtracts 1, when counting reaches threshold value, carries out fault alarm, thus reaches the effect reducing false alarm rate.
Beneficial effect of the present invention is:
The present invention has higher trouble diagnosibility, and can by fault isolation to each unit (LRU); And can fully test, guaranteed reliability and the security of equipment by all contingent faults of Test coverage circuitry system, substantially increase reliability and the testability of equipment.
