Lewis University Dr. James Girard Summer Undergraduate Research Program 2021 Faculty Mentor - Project Application
Lewis University Dr. James Girard Summer Undergraduate Research Program 2021 Faculty Mentor - Project Application Exploring the Use of High-level Parallel Abstractions and Parallel Computing for Functional and Gate-Level Simulation Acceleration Dr. Lucien Ngalamou Department of Engineering, Computing and Mathematical Sciences Abstract System-on-Chip (SoC) complexity growth has multiplied non-stop, and time-to- market pressure has driven demand for innovation in simulation performance. Logic simulation is the primary method to verify the correctness of such systems. Logic simulation is used heavily to verify the functional correctness of a design for a broad range of abstraction levels. In mainstream industry verification methodologies, typical setups coordinate the validation e↵ort of a complex digital system by distributing logic simulation tasks among vast server farms for months at a time. Yet, the performance of logic simulation is not sufficient to satisfy the demand, leading to incomplete validation processes, escaped functional bugs, and continuous pressure on the EDA1 industry to develop faster simulation solutions. In this research, we will explore a solution that uses high-level parallel abstractions and parallel computing to boost the performance of logic simulation. 1Electronic Design Automation 1 1 Project Description 1.1 Introduction and Background SoC complexity is increasing rapidly, driven by demands in the mobile market, and in- creasingly by the fast-growth of assisted- and autonomous-driving applications. SoC teams utilize many verification technologies to address their complexity and time-to-market chal- lenges; however, logic simulation continues to be the foundation for all verification flows, and continues to account for more than 90% [10] of all verification workloads. -

Review of FPD's Languages, Compilers, Interpreters and Tools
ISSN 2394-7314 International Journal of Novel Research in Computer Science and Software Engineering Vol. 3, Issue 1, pp: (140-158), Month: January-April 2016, Available at: www.noveltyjournals.com Review of FPD'S Languages, Compilers, Interpreters and Tools 1Amr Rashed, 2Bedir Yousif, 3Ahmed Shaban Samra 1Higher studies Deanship, Taif university, Taif, Saudi Arabia 2Communication and Electronics Department, Faculty of engineering, Kafrelsheikh University, Egypt 3Communication and Electronics Department, Faculty of engineering, Mansoura University, Egypt Abstract: FPGAs have achieved quick acceptance, spread and growth over the past years because they can be applied to a variety of applications. Some of these applications includes: random logic, bioinformatics, video and image processing, device controllers, communication encoding, modulation, and filtering, limited size systems with RAM blocks, and many more. For example, for video and image processing application it is very difficult and time consuming to use traditional HDL languages, so it’s obligatory to search for other efficient, synthesis tools to implement your design. The question is what is the best comparable language or tool to implement desired application. Also this research is very helpful for language developers to know strength points, weakness points, ease of use and efficiency of each tool or language. This research faced many challenges one of them is that there is no complete reference of all FPGA languages and tools, also available references and guides are few and almost not good. Searching for a simple example to learn some of these tools or languages would be a time consuming. This paper represents a review study or guide of almost all PLD's languages, interpreters and tools that can be used for programming, simulating and synthesizing PLD's for analog, digital & mixed signals and systems supported with simple examples. -

Where is the documentation? What is Verilog? What are HDLs? ● Hardware Description Languages (HDLs) are computer languages that describe digital circuits. ● The two most important HDLs are VHDL and Verilog / SystemVerilog. (SystemVerilog is Verilog with a lot of additional features added to the language.) ● Originally HDLs where only used for testing and documentation. But nowadays HDLs are also used as design entry (instead of e.g. drawing schematics). ● Converting HDL code to a circuit is called HDL Synthesis.
