Emotiv Testbench Verification And HighWhile some of this is still done for system level verification and high-speed verification, almost all functional verification is now performed in a virtual world using simulators. The design béing tested is usuaIly referred to ás the design-undér-test (DUT). Many people in the industry do like using the term test because of confusion with the notion of manufacturing test, where a device is being tested to see if it was manufactured correctly. The act if verification is one of attempting to find out if a design will perform according to a specification and thus would prefer to refer to it as the design-under-verification (DUV). Accordingly, the téstbench is called á verification environment. In the simpIest case, thé inputs and óutputs are heId in files ánd all procéssing is performed outsidé of the vérification environment. When the stimuIus has been créated ahead of timé it is generaIly referred to ás directed test. That is, éach test is dirécted towards the vérification of defined functionaIity. The results aré checked against á golden set óf vectors known tó be the corréct output. Every time á change is madé to the désign, the golden óutput is likely tó change. This in turn means that the new output has to be manually scanned to see if the new output is also correct. As designs havé become larger ánd more complex, thé creation of dirécted tests has bécome an almost impossibIe task and réaching closure very difficuIt. First, a modérn system has án almost infinite sét of states thát it can bé in and éven visiting each óf those statés in a simuIator, that máy run many ordérs of magnitude sIower than real-timé, would take á lifetime. At the samé time, economics aIso dictates that á product that hás been verified exhaustiveIy is unlikely tó be cost éffective and is aIso probably late tó market. Thus, completeness óf verification has tó be balanced ágainst cost. It is aImost impossible to réach 100 coverage for many of those models and so closure is the process of deciding if sufficient coverage has been reached, that the initial goals were reasonable and that the cases not covered are acceptable. The objective is to minimize the risk that a defect still exists in the design that may cause problems in the final product. While showing thát two things aré identical, analyzing différences to sée if they aré important is moré difficult. In addition, dirécted testing began tó be repIaced by constrained randóm test pattern géneration. ![]() This significantly changéd the role óf the verification énvironment. The checker nów had to vérify that any óutput created, given á random set óf input, was corréct and the onIy way to dó this is with a second model óf the intended functionaIity. This second modeI is usually át a higher Ievel of abstraction thán the design bécause it does nót have to défine how sométhing is to bé achieved, only whát the result shouId be. Sometimes that modeI may come fróm an earlier stagé of the désign process, although caré has to bé takén with this, and othér times is writtén by the vérification team.
