thumb Universal Test Specification Language (UTSL) is a programming language used to describe ASIC tests in a format that leads to an automated translation of the test specification into an executable test code. UTSL is platform independent and provided a code generation interface for a specific platform is available, UTSL code can be translated into the programming language of a specific Automatic Test Equipment (ATE). == History == Increased complexity of ASICs lead to requirements of more complex test programs with longer development times. An automated test program generation could simplify and speed up this process. Teradyne Inc. together with Robert Bosch GmbH agreed to developed a concept and a tool chain for an automated test-program generation.〔A. Drappa, J. Vollmar und P. Huber, “Automatic Test Program Generation for Automotive Devices”, International Test Conference (ITC), Austin, Texas USA, 2010, Paper 17.1.〕〔http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=5699253&tag=1〕〔A. Drappa, P. Huber und J. Vollmar, “Automatic Test Program Generation for Automotive Devices”, 23. GI/GMM/ITG-Workshop Universität Passau, 2011, Seite 81.〕 To achieve this a tester independent programming language was required. Hence, UTSL, a programming language that enables detailed description of tests that can be translated into the ATE specific programming language was developed. The ATE manufacturers need to provide a Test Program Generator that uses the UTSL test description as inputs and generates the ATE-specific test code with optimal resource mapping and better practice program code.〔R. Baumann, N. Nebel, “Die automatische Generierung von Testprogrammen im täglichen Einsatz”, 27. GI/GMM/ITG-Workshop, Bad Urach 2015, page 59.〕〔R. Baumann und N. Nebel, “Automated Test Program Generation for Automotive Devices”, Teradyne User Group (TUG) Conference, Fort Worth, TX, 2013.〕〔R. Baumann und N. Nebel, “Integrating Automated Test Program Generation in Your Daily Workflow Saves Time”, Teradyne User Group (TUG) Conference, Anaheim, California, 2014.〕 As long as the ATE manufacturer provides with the test program generator that can use UTSL as an input the cumbersome task of translating a test program from one platform to another can be significantly simplified. In other words, the task of rewriting of the test programs for a specific platform can be replaced by the automatically generating the code from the UTSL based test specification. Prerequisite for this is that the UTSL description of tests is sufficiently detailed with definition of the test technique as well as the description of all the necessary inputs and outputs.〔〔〔 Being a platform independent programming language, UTSL allows the engineers to read, analyse and modify the tests in the test specification regardless of the ATE at which the testing of the ASIC will be done. UTSL is based on C# and allows procedural programming and is class oriented. The classes contain sub-classes which in term have their sub-classes.〔“UTSL Universal Test Specification Language”. http://www.vde.com/de/fg/GMM/Arbeitsgebiete/FB7/FA7.1/Documents/utsl_reference.pdf .〕 left UTSL contains high amount of commands and test-functions. It also allows the usage of commonly known high level programming language syntax elements such as "if/then/else" and etc.〔 left 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Universal Test Specification Language」の詳細全文を読む スポンサード リンク
