Description
Technical field
The present invention relates to the monitoring technique of the communications field, further relate to a kind of devices and methods therefor that excited message is monitored.
Background technology
At present, for the design cycle and the development cost of reducing product, producer is before the new digital circuit product of exploitation communication class, at first adopt the working condition of analog and digital circuit logic on computers, be the digital circuit logic simulation process, then by to digital circuit logic emulation test, with the problem of finding that as much as possible digital circuit logic emulation exists, then update the problem that exists in the digital circuit logic emulation, so that can design more ripe digital circuit product.
At first, when emulation is tested to digital circuit logic, usually design excited message to impose on digital circuit logic by the tester according to the function point of digital circuit logic, industry is directly test with this test method definitions, promptly the function point that only can expect the tester is tested, therefore coverage rate is narrow, thereby may cause the situation of test leakage to take place.
Directly test is exemplified below:
Definition excited message type: address 2 bits; Message place Bao Changwei 14 bits; Excited message length is subjected to the long restriction of its place bag;
Test request: require respectively to produce 10 excited messages in the length range of 46~150 bits, 200~500 bits and 1000~1500 bits, the address of each excited message is same definite value;
Directly the way of test normally produces this 3 kinds of excited messages in proper order, every kind of excited message produces 10 and gets final product, so direct test can only impose on digital circuit logic respectively with these 30 excited messages, with to digital circuit logic emulation test, so its coverage rate is relatively narrow.
And at present, in carrying out digital circuit logic emulation testing process, industry adopts the mode of arbitrary excitation to impose on digital circuit logic to produce excited message usually, expectation reaches wider covering by the arbitrary excitation message, thereby reduce the probability of test leakage, industry is the arbitrary excitation test with this test method definitions.Although but above-mentioned mode by arbitrary excitation produces excited message to impose on digital circuit logic, can reduce the probability of test leakage, but owing to the result of the arbitrary excitation message that produces in the arbitrary excitation mode is difficult to prediction, therefore must monitor the excited message that arbitrary excitation produces, so that the tester can accurately learn the result of all kinds of excited messages that arbitrary excitation generates.
At above-mentioned direct test the cited case, then the implementation procedure of arbitrary excitation test is as follows:
The excited message that restriction will produce in legal range at random; And press test request and set 3 monitoring ranges, promptly be respectively 46~150 bits, 200~500 bits and 1000~1500 bits, set the target sample number in each monitoring range simultaneously, and a Sample Counter is set for each monitoring range;
Producing in the arbitrary excitation mode in the process of excited message, its message length in legal range at random, like this by a monitoring mechanism is set, take a sample with the excited message that arbitrary excitation is produced, and whether the excited message of censored sample hits above-mentioned three monitoring ranges, if hit, then the Sample Counter in the corresponding monitoring range is added 1.To reach the test request that in three scopes of 46~150 bits, 200~500 bits and 1000~1500 bits, respectively produces 10 excited messages respectively like this, the then actual excited message number that produces is bound to greater than 30, because in the arbitrary excitation process, the many excited messages that produce have dropped on outside the monitoring range, the type and the number thereof that impose on the excited message of digital circuit logic like this all can increase, and have therefore just enlarged the coverage rate to the digital circuit logic emulation testing.
In the prior art, when emulation is tested to digital circuit logic, adopt the e language to write arbitrary excitation mechanism usually, with generation arbitrary excitation message, and the production of monitoring arbitrary excitation message.Wherein the e language is to be submitted to a kind of emulation testing language of IEEE tissue as standard by the preparation that verisity company proposes.
But because the e language is a kind of new language that is exclusively used in emulation testing, so after many testers need learn and understand the e language, could use; Simultaneously since the testing tool that uses arbitrary excitation mechanism that the e language realizes and monitor mode to need special support e language support, and therefore the testing tool price of supporting the e language at present uses the e language to realize that there is the relatively poor defective of versatility in the monitor mode of arbitrary excitation message all than higher.
In addition, because e language self character has determined not to be supported in the defective that reads monitored results in the emulation testing process in real time by the monitor mode of the arbitrary excitation message of e language realization, by the time just can read monitored results thereby cause having only after test is finished, if monitored results does not meet the demands, the tester need analyze reason and remodify e language testing code, again test, this shows that its flexibility of arbitrary excitation monitoring messages mode that is realized by the e language is poor.
