Increased complexity of [[ASIC]]s lead to requirements of more complex test programs with longer development times. An automated test program generation could simplify and speed up this process. <ref name="ATE_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. </ref> <ref> http://ieeexplore.ieee.org/xpl/articleDetails.jsp?arnumber=5699253&tag=1 </ref> <ref> A. Drappa, P. Huber und J. Vollmar, “Automatic Test Program Generation for Automotive Devices”, 23. GI/GMM/ITG-Workshop Universität Passau, 2011, Seite 81. </ref> [[Teradyne]] Inc. together with [[Robert Bosch GmbH]] agreed to developed a concept and a tool chain for an automated test-program generation. 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 best practice program code.

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.

'''SerialPort and SerialDataFrame classes''' - <span style="color:#0000FF">"for device serial communications" </span>

'''Evaluate class''' - <span style="color:#0000FF">"data-logs the results and compares the results to the defined limits" </span>

UTSL also supports the unitls and scales wherever floating point numbers are used. This is essential for a language that describes a test program where the values can be returned as <span style="color:#0000FF">"'''V''', '''mV''', '''uV''', '''A''', '''mA''', '''uA'''" </span> and etc <ref name="ATE_Generation" />.
