Kalocsányi, Vít ; Kajan, Michal (referee) ; Dvořák, Vojtěch (advisor)
Tato práce se věnuje požadavku na důkladnou verifikaci při návrhu systému řízení BLDC motorů. V práci je vysvětlena funkční verifikace číslicových obvodů a univerzální verifikační metodika (UVM) a práce je zaměřena na návrh verifikačního prostředí s využitím této metodologie. Dále je v této práci vysvětlena typická struktura systému řízení BLDC motoru a definován způsob verifikace takového systému řízení. Dále je popsána implementace verifikačního prostředí a diskutovány přínosy zavedení UVM do verifikačního procesu.

Hardware Accelerated Functional Verification
Zachariášová, Marcela ; Kotásek, Zdeněk (referee) ; Kajan, Michal (advisor)
Funkční verifikace je jednou z nejrozšířenějších technik ověřování korektnosti hardwarových systémů podle jejich specifikace. S nárůstem složitosti současných systémů se zvyšují i časové požadavky kladené na funkční verifikaci, a proto je důležité hledat nové techniky urychlení tohoto procesu. Teoretická část této práce popisuje základní principy různých verifikačních technik, jako jsou simulace a testování, funkční verifikace, jakož i formální analýzy a verifikace. Následuje popis tvorby verifikačních prostředí nad hardwarovými komponentami v jazyce SystemVerilog. Část věnující se analýze popisuje požadavky kladené na systém pro akceleraci funkční verifikace, z nichž nejdůležitější jsou možnost jednoduchého spuštění akcelerované verze verifikace a časová ekvivalence akcelerovaného a neakcelerovaného běhu verifikace. Práce dále představuje návrh verifikačního rámce používajícího pro akceleraci běhů verifikace technologii programovatelných hradlových polí se zachováním možnosti spuštění běhu verifikace v uživatelsky přívětivém ladicím prostředí simulátoru. Dle experimentů provedených na prototypové implementaci je dosažené zrychlení úměrné počtu ověřovaných transakcí a komplexnosti verifikovaného systému, přičemž nejvyšší zrychlení dosažené v sadě experimentů je více než 130násobné.

Functional Verification Framework for Multi Buses Following the UVM Standard
Beneš, Tomáš ; Šišmiš, Lukáš (referee) ; Kekely, Lukáš (advisor)
This thesis focus on the design and subsequent implementation of a multi-bus verification environment using the principles of the Universal Verification Methodology (UVM). It also focus on the implementation of the verification of three FPGA components using multi-bus as input and output interfaces. The implementation of the environment and all verifications is written in SystemVerilog language using a library that implement the basic constructs for UVM. The achieved results of the work are functional and easily reusable when creating further verifications using multi-bus. The proposed environments can be used as a structure for creating other verification environments for other buses.

Portable Stimulus Scenarios Specification for RISC-V Processor Modules
Bardonek, Petr ; Bidlo, Michal (referee) ; Zachariášová, Marcela (advisor)
The thesis is focused on the design and implementation of the portable stimulus verification scenarios for selected Berkelium processor modules based on RISC-V architecture from Codasip. The aim of this work is to use new standard for Portable Stimulus developed by Accellera organization to design and implement portable stimulus scenarios using the Questa InFact tool from Mentor. The proposed portable stimulus scenarios are then linked to the already existing verification environments of the UVM methodology and then they are used for verification of the Berkelium processor modules based on RISC-V architecture. The last part of the thesis is the evaluation of portability of the implemented scenarios to the individual levels of the Berkelium processor based on RISC-V architecture (IP blocks, subsystems, system level), in which it tries to use the proposed scenarios across all verificated levels.

Functional Verification of Processor Execution Units
Valach, Lukáš ; Lengál, Ondřej (referee) ; Masařík, Karel (advisor)
The thesis deals with integration of functional verification into the design cycle of execution units in a hardware-software co-design environment of the Codasip system. The aim of the thesis is to design and implement a verification environment in SystemVerilog in order to verify automatically generated hardware representation of the execution units. In the introduction, advantages and basic methods of functional verification and principles of the Codasip system are discussed. Next chapters describe the process of design and implementation of the verification environment of arithmetic-logic unit as well as the analysis of the results of verification. In the end, a review of accomplished goals and the suggestions for future development of the verification environment are made.

Feedback Hardware Functional Verification
Santa, Marek ; Kajan, Michal (referee) ; Kořenek, Jan (advisor)
In the development process of digital circuits, it is often not possible to avoid introducing errors into systems that are being developed. Early detection of such errors saves money and time. This project deals with automation of feedback in functional verification of various data processing components. The goal of automatic feedback is not only to shorten the time needed to verify the functionality of a system, but mainly to improve verification coverage of corner cases and thus increase the confidence in the verified system. General functional and formal verification principles and practices are discussed, coverage metrics are presented, limitations of both techniques are mentioned and room for improvement of current status is identified. Design of feedback verification environment using a genetic algorithm is described in detial. The verification results are summarized and evaluated.

Order Book Updates Generator
Cienciala, Ondřej ; Zachariášová, Marcela (referee) ; Dvořák, Milan (advisor)
This thesis analyses messages that come from NYSE Arca and ISE exchanges and provides a description of design of stock exchange updates generator which is capable of generating constrained-random messages. It can be used for testing software that handles messages from an electronic stock exchange. Techniques of coverage-driven verification and constrained-random stimulus generation are discussed. Message generation is based on XML template and because of that the generator can be adjusted for various exchanges.

Hardware Accelerated Functional Verification of Processor
Funiak, Martin ; Kajan, Michal (referee) ; Zachariášová, Marcela (advisor)
Functional verification belongs among the current verification approaches. Functional verification checks the correctness of the implementation of the system, due to its specification. The weakness of the functional verification approach is time consumption caused by slow software simulation of implicitly parallel hardware systems. This paper presents a solution for using a hardware accelerated functional verification of the processor. The introductory chapters form the theoretical basis for the following chapters, that include a choice of solutions, an analysis, a design of a verification environment and implementation details. The conclusion includes tests of the final product, evaluation of the results and the future work perspectives.

Functional Verification of Robotic System Using UVM
Krajčír, Stanislav ; Čekan, Ondřej (referee) ; Zachariášová, Marcela (advisor)
One of the currently most used approaches for verification of hardware systems is functional verification. This master thesis describes design and implementation of a verification environment using UVM (Universal Verification Methodology) methodology for verifying the correctness of the robot controller in order to eliminate functional errors and faults of its implementation. The theoretical part of the thesis describes the basic information about functional verification, methodologies for creating verification environments, the SystemVerilog language and fault tolerance methodologies. The next part of thesis focuses on the design of the verification environment, its implementation and the creation of tests used to verify the correctness of the robot controller. Results of verification are discussed and evaluated in the conclusion of this work.
