Description
Technical field
The invention belongs to test field of measuring technique, and in particular to a kind of synchronous triggering side of execution of concurrent testing task
Method.
Background technology
In recent years, parallel test techniques receive much concern in test fields of measurement and have obtained increasingly being widely applied.With
Semiconductor test industry is used exemplified by parallel test techniques, current supporting ATE (Automatic Test
Equipment, ATE)/system (Automatic Test System, ATS) generally once loads a collection of treat using test fixture
Part is surveyed, these UUT test assignments (thread or process) are concurrently performed.These ATE/ATS effectively increase testing efficiency and test
Throughput.But, by used parallel test environment is mainly uniprocessor non-real time operating system (such as Windows), because
And the synchronization being difficult in the strict meaning performs multiple UUT test assignments, simply the multithreading in very short time interval/
Multi-course concurrency processing.Common practices as shown in figure 1, on the whole, operation user first by test assignment operation interface successively
Start each UUT test assignment, then each UUT test assignment is independently concurrently performed, each other without influence, in turn at occupancy
Manage device time and instrumentation resource；Seen in part, single UUT test assignments adjust test essential information, performed respectively in order
The action of individual presumptive test (including test mode settings, signal excitation, signal measurement, data acquisition, stored record, form are given birth to
Into ...) after all test actions are finished, change next UUT depending on condition and proceed processing, so circulation is repeatedly straight
To the batch testing for completing all UUT.It is summed up, it may be said that be that " overall parallelization asynchronism and concurrency is performed, partial serialization is suitable
Sequence processing ".Obviously, it is this at present to perform processing mode Shortcomings：It is ready that each UUT test assignment starts to execution from execution
Between there is gradually increased uncertain time delay, this time delay is more invented with UUT test assignment number of concurrent purpose increases
It is aobvious, thus the time-sensitive scene demand of multiple UUT test assignments requirement " performing simultaneously " can not be applied to.
Parallel test techniques be in order to solve the problem of serial order measuring technology testing efficiency is low, resource utilization is low and
Propose.Traditional serial order test can only enter within same moment or same time interval to a UUT test assignment
Row processing, and parallel test techniques " can then perform " multiple UUT test assignments simultaneously.This can not only improve testing efficiency,
Shorten the testing time, and the idle waiting state time of each test resource can be reduced, allow multiple UUT to share limited and treasured
Expensive test resource, effectively save testing cost.At present, the application of parallel test techniques is concentrated mainly on semiconductor production survey
The fields such as examination, software test, communication product testing protocol consistency and equipment repair detection.The country is ground to parallel test techniques
Study carefully in the ascendant, correlative study achievement is concentrated mainly on architecture, system model and task scheduling of parallel test system etc.
Aspect, not yet forms Systems Theory.
2.1.1 the concept of parallel test system
The method of testing that traditional Auto-Test System is used is the sequential testing (Sequence based on serial concept
Test), its basic ideas is as shown in Figure 2.When carrying out test assignment execution to a UUT, its test action is by advance order
Handled, until after its everything is disposed, can the follow-up UUT test assignments of start to process.If existing many
When individual UUT test assignments are performed, then handled successively according to order set in advance, i.e., one UUT test assignments processing
Finish and just start to perform next UUT test assignments.
The parallel test system concept for being different from traditional order test is given below.
Define 1.1 parallel test systems：Test system processor is in same time interval according to certain scheduling strategy
By the efficient parallel processing of the test sequence of multiple test objects in input system storage device, test system is in the same time
Multinomial test assignment can be run in section.The foundation that test sequence is divided is that data between consideration task are unrelated, resource without
Close and control the factor such as unrelated.Parallel test system is by the integration of resource and soft on the basis of conventional serial test system
What the change of part operational mode was developed and come.
At present, the framework of parallel test system according to can be divided into uniprocessor concurrent testing knot using processor number
Structure and parallel multiprocessor test structure.Wherein, parallel multiprocessor test structure has more than two processors, passes through height
Fast communication bus, shared memory space or input/output are tested, and have higher requirement to software and hardware resources.Press
Relation between multiprocessor is divided into distributed processing structure and the class of master-slave processing structure two.In distributed parallel test structure
Every computer can independently be effectively carried out test assignment, and realize by express network test synchronization and resource-sharing；
Principal and subordinate processor structure is then using laying under tribute and function is single from processor shares the part work of primary processor
Make, to mitigate the burden of primary processor, improve testing efficiency.Uniprocessor Parallel Test Architecture is then by appointing to different tests
The time for dispatching to distribute single processor processing task of business is so as to realize concurrent testing.Test assignment therein is with multiple lines
The form of journey (Multiple Threads) or multiple processes (Multiple Processes) is present, and passes through central processing unit
(Central Processing Unit, CPU) switching of the processor between thread or process is handled to complete test execution.Two
Person is comparatively, parallel multiprocessor test structure is higher, complicated to the hardware requirement of system, uniprocessor concurrent testing
The hardware requirement of structure is relatively low, simple in construction.Thus, generally it is applicable and can effectively reduces the still uniprocessor of testing cost simultaneously
Row test structure.
2.1.2 the advantage of parallel test techniques
Parallel test techniques substantially increase test throughput, improve test by the Optimum utilization to test resource
Resource utilization, the testing time is reduced, and then be effectively saved testing cost.It is mainly shown as：
Improve test throughput.Parallel test system is accomplished in several ways the dynamically distributes of test resource and optimization is adjusted
Degree, can be executed concurrently multiple UUT test assignments within the same time.Come from the point of view of batch testing, it is single by increasing
UUT quantity can just improve the efficiency of whole test system in the time of position.The efficiency of test system is higher, to test throughput
Raising degree it is higher.
Improve test resource utilization rate.Raising of the concurrent testing to test resource utilization rate mainly includes at 2 points, and one is to the greatest extent
Amount makes test resource in running order, and two be test resource is fully utilized.Concurrent testing task is constantly running,
Use, test resource is used by new test assignment application again once idle application test resource.In the ideal case,
In whole test process test resource be constantly in working condition, i.e. test resource be constantly in during whole test it is non-
Idle condition.
Reduce the testing time.When according to statistics, using sequential testing mode, the time of processor about 80% is in idle shape
State.By taking U.S. NI (National Instruments) company supervision test software TestStand experimental result as an example：In list
Under the conditions of processor multi-threaded parallel, the same UUT test sequences of TestStand running softwares, its concurrent testing are utilized
The time is expended under pattern than expending time reduction about 33% under serial order pattern.Testing time reduction effect is obvious.
2.2 prior art implementations
2.2.1 the implementation of concurrent testing
The implementation of concurrent testing mainly has three kinds of forms：The first is the concurrent testing for multiple UUT, its task
The object of scheduling is each UUT test assignment, one UUT test assignment of each UUT correspondences；Second is multiple on single UUT
The concurrent testing of test assignment, the object of its task scheduling is same UUT multiple test assignments；The third is then above two
The combination of the form of kind, i.e. scheduler object is multiple UUT multiple test assignments.In view of between the test assignment of these different scales
The problems such as needing to avoid deadlock, competition and starvation, the first form is obviously implemented the most directly, thus also by main flow
Ripe concurrent testing software is generally used.It is public that these concurrent testing softwares include U.S. Nl company's Ts estStand, U.S. TYX
TestBase of department etc., they are each provided with the concurrent testing solution for multiple UUT, are carried out by granularity unit of UUT
Task scheduling.
By taking the TestStand softwares that Nl companies of the U.S. are provided as an example, TestStand, which is used, is based on uniprocessor multithreading
Parallel Test Architecture, its task scheduling use Design of System Software in commonly use dispatching method is seized based on priority,
A kind of one cycle tests of UUT correspondences is sought, cycle tests priority can be set, ensures that many UUT are competing using lock (Lock) object
Exclusivity of some UUT to resource when striving.TestStand concurrent testing provides two kinds of models：Batch process model (Batch
Process Model) and concurrent process model (Parallel Process Model), as shown in Figure 3.Wherein, batch process
Multiple UUT test assignments are regard as one group in model, it is ensured that multiple UUT test assignments in the group start simultaneously at execution and waited
Processing terminates simultaneously.Middle test action is indifferent under batch process model default situations, all UUT test actions exist
It is completely independent in implementation procedure and parallel.Comparatively, UUT has to wait for most slow UUT tests under batch process model
Task could be tested at last after finishing to be terminated, it is clear that the testing time in idle state is longer.Batch process model is more should
For semiconductor production testing field；The application of concurrent process model is more universal, and each UUT test assignment is complete under the model
Independence and it is independent of each other.For single UUT, its test execution is serial process in order, from test is started until institute
There is test action to be finished, next UUT is optionally changed afterwards and proceeds processing.Ideally measuring executing process
In be not present competition, deadlock the problems such as, can increase substantially testing efficiency with test throughput.
In summary, either batch process model, or concurrent processing model, employed in parallel test system
Parallel test environment is mainly uniprocessor non-real time operating system (such as Windows), adds instrumentation, interface device
Constraint Deng critical resource is limited, and it is multiple that actually current various parallel test systems do not have real realization " performing simultaneously "
UUT test assignments, and only realize the UUT test assignments in Fixed Time Interval and concurrently perform processing.
Describe to have the concurrent testing task executing method in parallel test system at present below.
2.2.2 existing concurrent testing task executing method
Current existing concurrent testing task executing method, primarily focuses on and utilizes mature technology and shelf software and hardware resources
Comprehensive integration is carried out, is summed up and can be described as " concurrently execution, partial serialization sequential processes on the whole ".Below with application compared with
To be illustrated exemplified by universal TestStand software parallels process model (Parallel Process Model)：Such as Fig. 1 institutes
Show, on the whole, operation user starts each UUT test assignment successively first with test assignment operation interface, then each UUT
Test assignment is independently concurrently performed, each other without influence, and processor time and instrumentation resource are taken in turn；In part
See, single UUT test assignments adjust test essential information in order, performing the action of each presumptive test, (including test mode is set
Put, signal excitation, signal measurement, data acquisition, stored record, report generation ...) after all test actions are finished,
Next UUT is changed depending on user's operating condition and proceeds processing, and so circulation is repeatedly until all UUT of completion batch testing.
Obviously, from performing in flow, this execution method is " at overall parallelization asynchronism and concurrency execution, partial serialization order
Reason ".
Thus, this concurrent testing task executing method Shortcomings：Each UUT test assignment from start to it is ready between
In the presence of gradually increased uncertain time delay, it is impossible to suitable for the time-sensitive of each UUT test assignment " performing " simultaneously
Scape demand.With the increase of UUT parallel scales, the concurrent number of UUT test assignments necessarily increases, this uncertain time delay phenomenon
All the more it is serious！
Existing multiple UUT concurrent testings tasks carrying treatment technologies, by operating user to pass through software test task operating
Interface starts each UUT test assignment successively, and then each UUT test assignment is ready successively and independently concurrently performs, and accounts in turn
Dependence test is completed with processor time and instrumentation resource to act.The technology has the disadvantage that：
1st, each UUT test assignment from execution start to function it is ready between there is uncertain time delay.Due to simultaneously
Row test run environment is uniprocessor non-real time operating system (such as Windows), technology realize use multi-process or
Multithreaded architecture, be by processor between process or cross-thread switching come complete processing, this will necessarily just take processor
CPU time and memory source, thus time delay is inevitable.The processing of startup successively of UUT test assignments, is substantially one
Create thread or loading process, the process of the ready initialization of function.The CPU time started shared by processing procedure is longer, also
Mean that the ready time delay of UUT test assignments is bigger.Existed and other lines simultaneously as this starts processing procedure
Processor resource competition between journey or process, this time delay spacing that each UUT test assignment is performed is necessarily uncertain.
2nd, the demand scene of each UUT test assignment " performing simultaneously " can not be realized." performing simultaneously ", it is meant that each
UUT concurrent testings task must concurrently be performed in synchronization or very short time interval.UUT test assignments are from performing startup
To existing unpredictable time-delay between ready, necessarily cause to be difficult to " performing simultaneously ".Moreover, with UUT test assignments
The concurrent purpose increase of number, the uncertainty of this time delay is obvious all the more.Thus, prior art can not be applied to multiple UUT
The time-sensitive scene demand of test assignment requirement " performing simultaneously ".
