Current methodologies for built-in test pattern generation usually employ a predetermined linear feedback shift register (LFSR) in order to generate or decompress deterministic test patterns. As a direct consequence, the test pattern computation and the fault coverage are constrained to the preselected architecture. Work has been done to determine desirable characteristics in the LFSR to be used. Also, work has been done in the use of these predefined architectures, in order to compact the test data. In general, these methodologies take advantage of the large amount of don't care bits present in the test patterns, to accommodate the few specified bits to the output generated by the predefined LFSR. This dissertation explores the design of the LFSR as a built-in mechanism for test pattern generation in integrated circuits. The advantage of designing such devices is that the test set generation process is not constrained to a predefined LFSR mechanism, and the fault coverage is not affected. The methodologies presented in this work are based on cryptography concepts and heuristics to perform its computation. First, it is shown how these concepts can be adapted to test pattern generation. After this, methodologies are presented to generate one-dimensional and two-dimensional test sets. For the case of two-dimensional test set, the design of phase shifters is included.

Den ökade globalisering som råder gynnar internationell handel på många plan, vilket även har bidragit till att internprissättning blivit en allt mer central fråga. Däremot ställs det högre krav på att adressera de problem som systemet resulterar i. Detta med hänsyn till att ett internpris är av påverkande karaktär på organisationens resultat på grund av skattemässiga motiv och incitament från ledningen. Även om OECD:s riktlinjer TPG är utformade av det politiskt styrande organet i respektive medlemsland är dessa riktlinjer inte tvingande. Systemet möjliggör subjektivitet i internprissättning. Problematiken belyses i synnerhet när redovisningstraditioner och deras eventuella påverkan på internprissättningen i Sverige och Storbritannien tas i beaktning.Studien har som syfte att genom en komparativ analys undersöka hur Sveriges och Storbritanniens redovisningstraditioner påverkar respektive lands tolkning av TPG. Ländernas skattemyndigheter, Skatteverket och HMRC, har gett ut en handledning respektive en intern manual rörande internprissättning där myndighetens tolkning av TPG framgår.Studien är en innehållsanalys av kvalitativ karaktär och datamaterialet som har använts är textutdrag från myndigheternas handledning och manual samt respektive lands lagstiftning på vissa områden. Studien har som ambition att undersöka fyra områden avseende internprissättning, myndigheternas referering till gällande rätt, armlängdsprincipen, metoder för prissättning och bevisförfarande. Tolkningsmodellen som har använts i studien har utvecklats fram ifrån Johanssons (2010) modell avseende substance over form. Tolkningsmodellen tillsammans med den teoretiska referensramen har fungerat som ett verktyg i analysen kring hur redovisningstraditionerna i respektive land påverkar tolkningen av TPG.Studiens slutsats indikerar att det finns inslag av redovisningstraditionerna i respektive lands tolkning av TPG. Både Storbritannien och Sverige refererar till OECD kontinuerligt men studien har resulterat i vissa skillnader som belyser det faktum att länderna har olika redovisningstraditioner. I Skatteverkets handledning identifierar resultatet vissa inslag av den kontinentala redovisningstradition som Sverige präglas av, det påträffas även inslag av det regelbaserade synsättet samt spår av det rättssystem som karaktäriserar Sverige, code law. Resultatet visar även att Storbritanniens redovisningstraditioner framträder i HMRC:s tolkning av TPG. Det återfinns inslag av den anglosaxiska traditionen, det principbaserade synsättet och även här syns spår av deras rättssystem, common law. Studien bidrar med en ökad förståelse kring hur nationella redovisningstraditioner påverkar tolkningen av internationella riktlinjer. Den bidrar även med en praktisk kunskap för företag, myndigheter och internationella verkställande organ. / Increased globalization stimulates international trade in many ways. It has led to increased importance of transfer pricing. However, there is a need to address several issues that have arisen since a transfer price affects the organization's profit or loss due to tax consequences and incentives from management. Although the guidelines known as TPG are drafted by the governments in members’ states, these guidelines are not mandatory. The system allows for subjectivity in transfer pricing. The problem is can be demonstrated by comparing the accounting traditions and their possible impact on transfer pricing in Sweden and the UK.The purpose of the study is to investigate how Sweden's and Britain's accounting traditions affect the countries' interpretation of the TPG. The tax authorities of these countries, the Swedish Tax Agency and HMRC, have each issued a guide and an internal manual on transfer pricing, which explains the authorities’ interpretation of the TPG. The aim of the study is to make a comparative analysis of these guides and internal manuals to see if and how the countries’ interpretation of the TPG differ due to the countries’ accounting traditions. Further, the study is a content analysis of qualitative nature and the data used has been extracted from the authorities' guide and internal manual, as well as the legislation of each country in certain areas. The aim of the study is to investigate four areas of transfer pricing, the authorities' reference to current law, the arm's length principle, pricing methods and evidence procedures. The research model used in this study has been developed from Johanssons (2010) model regarding substance over form. The resarch model together with the theoretical reference framework have served as a tool in the analysis of how accounting traditions in each country affect the interpretation of TPG.The study’s conclusion indicates that there are elements of accounting traditions in each country’s interpretation of TPG. Both the UK and Sweden refer to the OECD repeatedly but the study has resulted in some differences highlighting the fact that the countries have different accounting traditions. In the Swedish Tax Agency’s guidance, the result identifies certain elements of the continental accounting tradition that Sweden is characterized by, it also finds elements of the rule-based approach as well as traces of the legal system code law that characterizes Sweden. Likewise, the result also shows that Britain's accounting traditions appear in HMRC's interpretation of TPG. There are elements of Anglo-Saxon tradition, the principle-based approach, and also traces of their legal system common law. The study contributes to an increased understanding of how national accounting traditions affect the interpretation of international guidelines. It also provides useful information for companies, authorities and international executive agencies.This paper is hereinafter written in Swedish.
