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 technique
In recent years, parallel test techniques are concerned and are more and more widely used in test fields of measurement.With
For the used parallel test techniques of semiconductor test industry, current mating automatic test equipment (Automatic Test
Equipment, ATE)/system (Automatic Test System, ATS) usually using test fixture once loads it is a collection of to
Part is surveyed, these UUT test assignments (thread or process) are concurrently executed.These ATE/ATS effectively increase testing efficiency and test
Throughput.But since used parallel test environment is mainly uniprocessor non-real time operating system (such as Windows), because
And the synchronization on being difficult to realize strictly to look like executes multiple UUT test assignments, only the multithreading in very short time interval/
Multi-course concurrency processing.Common practices is as shown in Figure 1, on the whole, operation user passes through test assignment operation interface successively first
Start each UUT test assignment, then each UUT test assignment independently concurrently executes, between each other without influence, in turn at occupancy
Manage device time and instrumentation resource；It is seen on part, single UUT test assignment adjusts test essential information in order, executes respectively
The movement of a presumptive test (including test mode setting, signal excitation, signal measurement, data acquisition, storage record, report life
At ...) after all test actions are finished, next UUT is changed depending on condition and continues to handle, and so circulation is repeatedly straight
To the batch testing for completing all UUT.It is summed up, it may be said that be that " whole parallelization asynchronism and concurrency executes, partial serialization is suitable
Sequence processing ".Obviously, at present this executions processing mode Shortcomings: each UUT test assignment from execution start to execution it is ready
Between there is the uncertain time delay gradually increased, this time delay more invents with UUT test assignment number of concurrent purpose increase
It is aobvious, thus the time-sensitive scene demand that multiple UUT test assignments require " being performed simultaneously " can not be suitable for.
Parallel test techniques be in order to solve the problems, such as serial order measuring technology testing efficiency is low, resource utilization is low and
It proposes.Traditional serial order test within the same moment or same time interval can only to a UUT test assignment into
Row processing, and parallel test techniques " can then be performed simultaneously " multiple UUT test assignments.This can not only improve testing efficiency,
Shorten the testing time, and the idle waiting state time of each test resource can be reduced, allows multiple UUT to share limited and precious
Expensive test resource, effectively save testing cost.Currently, 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.Parallel test techniques are ground the country
Study carefully in the ascendant, related research result is concentrated mainly on architecture, system model and task schedule of parallel test system etc.
Aspect, not yet formation Systems Theory.
2.1.1 the concept of parallel test system
The test method that traditional Auto-Test System uses is the sequential testing (Sequence based on serial concept
Test), basic ideas are as shown in Figure 2.When carrying out test assignment execution to a UUT, test action is by sequence in advance
It is handled, until subsequent UUT test assignment can be started to process after its everything is disposed.It is more if it exists
It when a UUT test assignment executes, is then successively handled according to preset sequence, i.e. a UUT test assignment processing
It finishes and just starts to execute next UUT test assignment.
The parallel test system concept for being different from traditional order test is given below.
Define 1.1 parallel test systems: test macro processor is in same time interval according to certain scheduling strategy
Input system is stored to the efficient parallel processing of test sequence of multiple test objects in equipment, test macro is in the same time
Multinomial test assignment can be run in section.The foundation that test sequence divides be data between consideration task are unrelated, resource without
Close and control the factors such as unrelated.Parallel test system is on the basis of conventional serial test macro by the integration of resource and soft
What the change of part operational mode was developed.
Currently, 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.It presses
Relationship between multiprocessor is divided into two class of distributed processing structure and master-slave processing structure.Distributed parallel is tested in structure
Every computer can independently be effectively carried out test assignment, and test synchronization and resource-sharing are realized by high speed network；
Principal and subordinate processor structure is then that the part work of primary processor is shared using the slave processor for laying under tribute and having a single function
Make, to mitigate the burden of primary processor, improve testing efficiency.Uniprocessor Parallel Test Architecture is then by appointing to different tests
The scheduling of business handles the time of task to distribute single processor to realize concurrent testing.Test assignment therein is with multiple lines
The form of journey (Multiple Threads) or multiple processes (Multiple Processes) exists, 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 to the hardware requirement of system, structure is complicated, uniprocessor concurrent testing
The hardware requirement of structure is lower, structure is simple.Thus, it is generally applicable in and the still uniprocessor of testing cost can be effectively reduced 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 reduces the testing time, and then is effectively saved testing cost.It is mainly shown as:
Improve test throughput.Parallel test system is accomplished in several ways the dynamic allocation 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
The quantity of UUT just can be improved the efficiency of entire test macro in the time of position.The efficiency of test macro is higher, to test throughput
Raising degree it is higher.
Improve test resource utilization rate.Concurrent testing mainly includes two o'clock to the raising of test resource utilization rate, first is that the greatest extent
Amount keeps test resource in running order, second is that test resource is made to be fully utilized.Concurrent testing task is constantly running,
It uses to application test resource, test resource is used by new test assignment application again once idle.In the ideal case,
Test resource is constantly in working condition in entire test process, i.e. test resource is constantly in non-during entire test
Idle state.
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 the experimental result of U.S. NI (National Instruments) company supervision test software TestStand as an example: in list
Under the conditions of processor multi-threaded parallel, same UUT test sequence, concurrent testing are run using TestStand software
The time is expended under mode than expending time reduction about 33% under serial order mode.It is obvious that testing time reduces effect.
2.2 prior art implementations
2.2.1 the implementation of concurrent testing
There are mainly three types of forms for the implementation of concurrent testing: the first is the concurrent testing for multiple UUT, task
The object of scheduling is each UUT test assignment, the corresponding UUT test assignment of each UUT；Second is multiple on single UUT
The concurrent testing of test assignment, the object of task schedule are multiple test assignments of the same UUT；The third is then front two
Multiple test assignments that the combination of kind form, i.e. scheduler object are multiple UUT.In view of between the test assignment of these different scales
The problems such as avoiding deadlock, competition and starvation is needed, the first form obviously implements the most directly, thus also by mainstream
Mature concurrent testing software is generallyd use.These concurrent testing softwares include U.S. Nl company's T estStand, the U.S. TYX public affairs
The TestBase etc. of department, they are each provided with the concurrent testing solution for multiple UUT, carry out by granularity unit of UUT
Task schedule.
For the TestStand software provided by the Nl company, the U.S., TestStand, which is used, is based on uniprocessor multithreading
Parallel Test Architecture, task schedule wanted using commonly dispatching method is seized priority-based in Design of System Software
A kind of corresponding cycle tests of UUT is sought, settable cycle tests priority ensures that more UUT are competing using lock (Lock) object
Exclusivity of some UUT to resource when striving.The concurrent testing of TestStand 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
Using multiple UUT test assignments as one group in model, it is ensured that multiple UUT test assignments in the group start simultaneously at execution and waiting
It handles while terminating.Intermediate test action item is indifferent under batch process model default situations, all UUT test action items exist
It is completely independent in implementation procedure and parallel.Comparatively, UUT has to wait for most slow UUT test under batch process model
Could test at last after task terminates, it is clear that the testing time in idle state is longer.Batch process model is more to answer
For semiconductor production testing field；The application of concurrent process model is more universal, and each UUT test assignment is complete under the model
It independence and is independent of each other.For single UUT, test execution is serial process in order, from starting test until institute
There is test action to be finished, optionally replaces next UUT later and continue to handle.Ideally measuring executing process
In there is no competition, deadlock the problems such as, can increase substantially testing efficiency and test throughput.
In conclusion either batch process model or concurrent processing model, as employed in parallel test system
Parallel test environment is mainly uniprocessor non-real time operating system (such as Windows), in addition instrumentation, interface device
The restrict of equal critical resources, there is no really realize that " being performed simultaneously " is multiple for actually current various parallel test systems
UUT test assignment, and only realize the UUT test assignment in Fixed Time Interval and concurrently execute processing.
The concurrent testing task executing method once having at present in parallel test system is described 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 executing on the whole, partial serialization sequential processes ".Below with application compared with
To be illustrated for universal TestStand software parallel process model (Parallel Process Model): such as Fig. 1 institute
Show, on the whole, operates user first with test assignment operation interface and successively start each UUT test assignment, then each UUT
Test assignment independently concurrently executes, and between each other without influence, occupies processor time and instrumentation resource in turn；On part
It sees, single UUT test assignment adjusts that test essential information, executing the movement of each presumptive test, (including test mode is set in order
Set, signal excitation, signal measurement, data acquisition, storage record, report generation ...) after all test actions are finished,
It changes next UUT depending on user's operation condition to continue to handle, so circulation is repeatedly until the batch testing of all UUT of completion.
Obviously, from executing in process, this execution method is that " whole parallelization asynchronism and concurrency executes, at partial serialization sequence
Reason ".
Thus, this concurrent testing task executing method Shortcomings: each UUT test assignment is from starting between ready
In the presence of the uncertain time delay gradually increased, the time-sensitive field of each UUT test assignment " being performed simultaneously " can not be suitable for
Scape demand.With the increase of UUT parallel scale, the concurrent number of UUT test assignment necessarily increases, this uncertain time delay phenomenon
It is more serious！
Existing multiple UUT concurrent testing task execution processing techniques pass through software test task operating by operation user
Interface successively starts each UUT test assignment, and then each UUT test assignment is successively ready and independently concurrently executes, and accounts in turn
Dependence test movement is completed with processor time and instrumentation resource.The technology has the following disadvantages:
1, each UUT test assignment from execution start to function it is ready between there are uncertain time delays.Due to simultaneously
Row test run environment is uniprocessor non-real time operating system (such as Windows), technology realize using multi-process or
Multithreaded architecture, be by processor between process or cross-thread switching to complete to handle, this will necessarily just occupy processor
CPU time and memory source, thus time delay is inevitable.The successively starting of UUT test assignment is handled, and is substantially one
Create thread or load process, the process of the ready initialization of function.The starting treatment process occupied CPU time is longer, also
Mean that the ready time delay of UUT test assignment is bigger.Simultaneously as this starting treatment process there is with other lines
Processor resource competition between journey or process, this time delay spacing that each UUT test assignment executes are necessarily uncertain.
2, it cannot achieve the demand scene of each UUT test assignment " being performed simultaneously "." being performed simultaneously ", it is meant that each
UUT concurrent testing task must concurrently execute in synchronization or very short time interval.UUT test assignment is from executing starting
To existing unpredictable time-delay between ready, necessarily cause to be difficult to realize " being performed simultaneously ".Moreover, with UUT test assignment
The concurrent purpose of number increases, and the uncertainty of this time delay is more obvious.Thus, the prior art can not be suitable for multiple UUT
Test assignment requires the time-sensitive scene demand of " being performed simultaneously ".
