Co-Simulation Between Cλash and Traditional Hdls
MASTER THESIS CO-SIMULATION BETWEEN CλASH AND TRADITIONAL HDLS Author: John Verheij Faculty of Electrical Engineering, Mathematics and Computer Science (EEMCS) Computer Architecture for Embedded Systems (CAES) Exam committee: Dr. Ir. C.P.R. Baaij Dr. Ir. J. Kuper Dr. Ir. J.F. Broenink Ir. E. Molenkamp August 19, 2016 Abstract CλaSH is a functional hardware description language (HDL) developed at the CAES group of the University of Twente. CλaSH borrows both the syntax and semantics from the general-purpose functional programming language Haskell, meaning that circuit de- signers can define their circuits with regular Haskell syntax. CλaSH contains a compiler for compiling circuits to traditional hardware description languages, like VHDL, Verilog, and SystemVerilog. Currently, compiling to traditional HDLs is one-way, meaning that CλaSH has no simulation options with the traditional HDLs. Co-simulation could be used to simulate designs which are defined in multiple lan- guages. With co-simulation it should be possible to use CλaSH as a verification language (test-bench) for traditional HDLs. Furthermore, circuits defined in traditional HDLs, can be used and simulated within CλaSH. In this thesis, research is done on the co-simulation of CλaSH and traditional HDLs. Traditional hardware description languages are standardized and include an interface to communicate with foreign languages. This interface can be used to include foreign func- tions, or to make verification and co-simulation possible. Because CλaSH also has possibilities to communicate with foreign languages, through Haskell foreign function interface (FFI), it is possible to set up co-simulation. The Verilog Procedural Interface (VPI), as defined in the IEEE 1364 standard, is used to set-up the communication and to control a Verilog simulator. -

Tan Copyright by Scott Spencer Sirowy 2010 The Dissertation of Scott Spencer Sirowy is approved: Committee Chairperson University of California, Riverside ABSTRACT OF THE DISSERTATION Emulation of SystemC Applications for Portable FPGA Binaries by Scott Spencer Sirowy Doctor of Philosophy, Graduate Program in Computer Science University of California, Riverside, June 2010 Dr. Frank Vahid, Chairperson As FPGAs become more common in mainstream general-purpose computing platforms, capturing and distributing high-performance implementations of applications on FPGAs will become increasingly important. Even in the presence of C-based synthesis tools for FPGAs, designers continue to implement applications as circuits, due in large part to allow for capture of clever spatial, circuit-level implementation features leading to superior performance and efficiency. We demonstrate the feasibility of a spatial form of FPGA application capture that offers portability advantages for FPGA applications unseen with current FPGA binary formats. We demonstrate the portability of such a distribution by developing a fast on-chip emulation framework that performs transparent optimizations, allowing spatially-captured FPGA applications to immediately run on FPGA platforms without costly and hard-to-use synthesis/mapping tool flows, and sometimes faster than PC-based execution. We develop several dynamic and transparent optimization techniques, including just-in-time compilation , bytecode acceleration , and just-in-time synthesis that take advantage of a platform’s available resources, resulting in iv orders of magnitude performance improvement over normal emulation techniques and PC-based execution. -
Hardware Description Languages Compared: Verilog and Systemc

Such additions increases, engineers are now more than ever include constructs for concurrency, time notion, integrating component modeling by means of communication, reactivity and hardware data hardware description languages (HDLs) in the types. design process. The recent addition of SystemC to As described by Edwards [1], VLSI an already competitive arena of HDLs dominated verification involves an initial simulation done in by Verilog and VHDL, calls for a direct C or C++, usually for proof of concept purposes, comparison to expose potential advantages and followed by translation into an HDL, simulation of flaws of this newcomer. This paper presents such the model, applying appropriate corrections, differences and similarities, specifically between hardware synthesization and further iterative Verilog and SystemC, in effort to better categorize refinement. SystemC is able to shorten this the scopes of the two languages. Results are based process by combining the first two steps. on simulation conducted in both languages, for a Consequently, this also decreases time to market model with equal specifications. for a manufacturer. Generally a comparison between two computer languages is based on the number of Introduction lines of code and execution time required to achieve a specific task, using the two languages.

Real-Time Operating System Modelling and Simulation Using Systemc
Real-Time Operating System Modelling and Simulation Using SystemC Ke Yu Submitted for the degree of Doctor of Philosophy Department of Computer Science June 2010 Abstract Increasing system complexity and stringent time-to-market pressure bring chal- lenges to the design productivity of real-time embedded systems. Various System- Level Design (SLD), System-Level Design Languages (SLDL) and Transaction- Level Modelling (TLM) approaches have been proposed as enabling tools for real-time embedded system specification, simulation, implementation and verifi- cation. SLDL-based Real-Time Operating System (RTOS) modelling and simula- tion are key methods to understand dynamic scheduling and timing issues in real- time software behavioural simulation during SLD. However, current SLDL-based RTOS simulation approaches do not support real-time software simulation ade- quately in terms of both functionality and accuracy, e.g., simplistic RTOS func- tionality or annotation-dependent software time advance. This thesis is concerned with SystemC-based behavioural modelling and simu- lation of real-time embedded software, focusing upon RTOSs. The RTOS-centric simulation approach can support flexible, fast and accurate real-time software tim- ing and functional simulation. They can help software designers to undertake real- time software prototyping at early design phases. The contributions in this thesis are fourfold. Firstly, we propose a mixed timing real-time software modelling and simula- tion approach with various timing related techniques, which are suitable for early software modelling and simulation. We show that this approach not only avoids the accuracy drawback in some existing methods but also maintains a high simu- lation performance. Secondly, we propose a Live CPU Model to assist software behavioural timing modelling and simulation. -
Integrating Systemc Models with Verilog Using the Systemverilog
Integrating SystemC Models with Verilog and SystemVerilog Models Using the SystemVerilog Direct Programming Interface Stuart Sutherland Sutherland HDL, Inc. [email protected] ABSTRACT The Verilog Programming Language Interface (PLI) provides a mechanism for Verilog simulators to invoke C programs. One of the primary applications of the Verilog PLI is to integrate C- language and SystemC models into Verilog simulations. But, Verilog's PLI is a complex interface that can be daunting to learn, and often slows down simulation performance. SystemVerilog includes a new generation of a Verilog to C interface, called the “Direct Programming Interface” or “DPI”. The DPI replaces the complex Verilog PLI with a simple and straight forward import/ export methodology. • How does the SystemVerilog DPI work, and is it really easier to use than the Verilog PLI? • Can the SystemVerilog DPI replace the Verilog PLI for integrating C and SystemC models with Verilog models? • Is the SystemVerilog DPI more efficient (for faster simulations) that the Verilog PLI? • Is there anything the SystemVerilog DPI cannot do that the Verilog PLI can? This paper addresses all of these questions. The paper shows that if specific guidelines are followed, the SystemVerilog DPI does indeed simplify integrating SystemC models with Verilog models.

Parallel Systemc Simulation for Electronic System Level Design
Parallel SystemC Simulation for Electronic System Level Design Von der Fakultät für Elektrotechnik und Informationstechnik der Rheinisch–Westfälischen Technischen Hochschule Aachen zur Erlangung des akademischen Grades eines Doktors der Ingenieurwissenschaften genehmigte Dissertation vorgelegt von Diplom–Ingenieur Jan Henrik Weinstock aus Göttingen Berichter: Universitätsprofessor Dr. rer. nat. Rainer Leupers Universitätsprofessor Dr.-Ing. Diana Göhringer Tag der mündlichen Prüfung: 19.06.2018 Diese Dissertation ist auf den Internetseiten der Hochschulbibliothek online verfügbar. Abstract Over the past decade, Virtual Platforms (VPs) have established themselves as essential tools for embedded system design. Their application fields range from rapid proto- typing over design space exploration to early software development. This makes VPs a core enabler for concurrent HW/SW design – an indispensable design approach for meeting today’s aggressive marketing schedules. VPs are essentially a simulation of a complete microprocessor system, detailed enough to run unmodified target binary code. During simulation, VPs provide non-intrusive debugging access as well as re- porting on non-functional system parameters, such as execution timing and estimated power and energy consumption. To accelerate the construction of a VP for new systems, developers typically rely on pre-existing simulation environments. SystemC is a popular example for this and has become the de-facto reference for VP design since it became an official IEEE stan- dard in 2005. Since then, however, SystemC has failed to keep pace with its user’s demands for high simulation speed, especially when embedded multi-core systems are concerned. Because SystemC only utilizes a single processor of the host computer, the underlying sequential discrete event simulation algorithm becomes a performance bottleneck when simulating multiple virtual processors. -
