Abstract
The invention discloses a verification test instance judgment method comprising the steps that a test instance drives a verification environment to emit a motivation and the verification environment detects whether a response of a module to be tested is correct at a simulation stage; after all motivations are completely sent and collection of the responses is completed, if a function coverage rate cannot reach 100%, it means that the test instance does not emit the motivation according to preset and emits a signal that is not passed by error simulation of the test instance. According to the method provided by the invention, whether the test instance completes needed functions can be automatically judged, and verification errors can be reduced.
Description
Technical field
The present invention relates to simulating, verifying field, more particularly to a kind of verification test cases (referred to as " test case ", similarly hereinafter) are sentenced
Disconnected method.
Background technology
The function of design to be verified in simulating, verifying, is excited by test case.With checking propulsion, the modification of design,
Whether checking target is guaranteed always in whole verification process at the beginning, and checking test case is in the later stage only by verification environment
Output by or unsuccessfully carry out result of determination, if test case does not have it is anticipated that sending excitation, and target to be verified is not yet
Meeting output error result, this just leaves certain hidden danger.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of checking test case determination methods, automatically whether can judge test case
Complete the function of needing, reduce checking error.
For solving above-mentioned technical problem, the checking test case determination methods of the present invention adopt the following technical scheme that realization：
In simulation stage, test case drives verification environment to send excitation, and verification environment detects whether the response of module to be measured is correct；All
Excitation all sends, after response collection finishes, if function coverage can not reach 100% then it is assumed that test case is not according to pre-
If sending excitation, send the signal that the emulation of test case mistake is not passed through.
The present invention, compared with traditional test case determination methods, increased the inspection that checking objective function is covered, not only examines
The function of looking into target to be verified, whether normally additionally it is possible to check that the function of emulation is real needs, is returning checking on a large scale
In being capable of more preferable testing result.
The present invention passes through on the basis of traditional function result judgement, by adding function coverage point and using grand
Definition controls, and different test cases opens different function coverage points, examines after test case completes to encourage the collection sending and responding
Look into the percentage of coverage of function coverage point, judge whether test case has completed the function of needing such that it is able to automatic.
The present invention proposes a kind of extra decision method of checking test case it is adaptable to all sophisticated functions slave modules are to system
Checking, be automatic Verification, return checking effective decision means.
Brief description
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings：
Fig. 1 is described checking test case determination methods one embodiment flow chart.
Specific embodiment
The function of chip needs substantial amounts of checking test case to be verified, test case sends specific or random excitation, leads to
Result is obtained, response results are correctly the correct or wrong main decision conditions of test case result after crossing module response to be measured.
The comparison result that verification environment can automate, because it has been inefficient that the quantity of test case is significantly increased rear hand inspection, high mistake
Means, automatically check ability efficiently and accurately completes task by mistake.But the automatic problem checking is whether test case is really sent out
Gone out the excitation needing, if excite the function of needing checking because unwanted excitation also can allow module to be measured to
Go out response, verification environment also can be correct according to this result judgement.But real being not intended to so of this test case, though
So test case is correct when writing debugging, and with the progress of checking, verification environment can be changed, and module to be measured can repair problem,
The improvement of even test case itself is likely to lead to this non-functional mistake it is ensured that the intention of test case is from checking start to finish
Maintaining is unanimously the main contents of the present invention.
With reference to Fig. 1, described checking test case determination methods are described in further detail：
In the demonstration plan stage, need to plan the function that test case needs complete, by document come decomposition description basic training
Can, and the combination of these functions is embodied also by document.In conjunction with following table, it is exemplified below：
The basic function of chip to be measured includes, function one, function two and function three, and function one can be sent out with three simultaneously simultaneously
Raw, function one can occur with three with two again simultaneously, and test case one needs function one and function three, simultaneously need to function one and function
The scene that San Tong method occurs.Test case two needs function one, function two and function three, simultaneously need to the simultaneous field of three functions
Scape, so can start most by the intention of test case pass through document storing under, and by document processing program generate correspondence
Macro switch file.
When verification environment is set up, need all functions one to be monitored, function two and function three, and they are different
The scene of combination describes out by function coverage bleeding point, and the switch that these coverage rates are collected needs by above generating
Grand controlling.Add the judgement to function coverage result simultaneously on simulation result judges, be sent in all excitations,
After response collection finishes, it is considered as test case and does not send excitation according to default if function coverage can not reach 100%,
Need to quote test case mistake and emulate not pass through.
In simulation stage, test case drives verification environment to send excitation, and whether just verification environment detects the response of module to be measured
Really, can determine whether the function of needing be excited by manual type, simultaneously institute's function in need all pass through grand open, and
Unwanted function is come in all without addition it can be ensured that function coverage result is 100%, due to having in checking afterwards
The inspection of function coverage result is it is only necessary to pass through the output result of verification environment it may determine that whether function is normal,
Whether the function of sending is initial intention, or even with the progress verified it is only necessary to whether concern simulation result correctly can
To judge whether test case is always maintained at original intention, do not have to deviate from.
Above by specific embodiment, the present invention is described in detail, but these have not been constituted to the present invention's
Limit.Without departing from the principles of the present invention, those skilled in the art also can make many deformation and improve, these
Should be regarded as protection scope of the present invention.
