AN 307: Altera Design Flow for Xilinx Users Supersedes Information Published in Previous Versions
Altera Design Flow for Xilinx Users June 2005, ver. 5.0 Application Note 307 Introduction Designing for Altera® Programmable Logic Devices (PLDs) is very similar, both in concept and in practice, to designing for Xilinx PLDs. In most cases, you can simply import your register transfer level (RTL) into Altera’s Quartus® II software and begin compiling your design to the target device. This document will demonstrate the similar flows between the Altera Quartus II software and the Xilinx ISE software. For designs, which the designer has included Xilinx CORE generator modules or instantiated primitives, the bulk of this document guides the designer in design conversion considerations. Who Should Read This Document The first and third sections of this application note are designed for engineers who are familiar with the Xilinx ISE software and are using Altera’s Quartus II software. This first section describes the possible design flows available with the Altera Quartus II software and demonstrates how similar they are to the Xilinx ISE flows. The third section shows you how to convert your ISE constraints into Quartus II constraints. f For more information on setting up your design in the Quartus II software, refer to the Altera Quick Start Guide For Quartus II Software. The second section of this application note is designed for engineers whose design code contains Xilinx CORE generator modules or instantiated primitives. The second section provides comprehensive information on how to migrate a design targeted at a Xilinx device to one that is compatible with an Altera device. If your design contains pure behavioral coding, you can skip the second section entirely. -

Implementation, Verification and Validation of an Openrisc-1200
(IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 10, No. 1, 2019 Implementation, Verification and Validation of an OpenRISC-1200 Soft-core Processor on FPGA Abdul Rafay Khatri Department of Electronic Engineering, QUEST, NawabShah, Pakistan Abstract—An embedded system is a dedicated computer system in which hardware and software are combined to per- form some specific tasks. Recent advancements in the Field Programmable Gate Array (FPGA) technology make it possible to implement the complete embedded system on a single FPGA chip. The fundamental component of an embedded system is a microprocessor. Soft-core processors are written in hardware description languages and functionally equivalent to an ordinary microprocessor. These soft-core processors are synthesized and implemented on the FPGA devices. In this paper, the OpenRISC 1200 processor is used, which is a 32-bit soft-core processor and Fig. 1. General block diagram of embedded systems. written in the Verilog HDL. Xilinx ISE tools perform synthesis, design implementation and configure/program the FPGA. For verification and debugging purpose, a software toolchain from (RISC) processor. This processor consists of all necessary GNU is configured and installed. The software is written in C components which are available in any other microproces- and Assembly languages. The communication between the host computer and FPGA board is carried out through the serial RS- sor. These components are connected through a bus called 232 port. Wishbone bus. In this work, the OR1200 processor is used to implement the system on a chip technology on a Virtex-5 Keywords—FPGA Design; HDLs; Hw-Sw Co-design; Open- FPGA board from Xilinx. -

Softcores for FPGA: the Free and Open Source Alternatives
Softcores for FPGA: The Free and Open Source Alternatives Jeremy Bennett and Simon Cook, Embecosm Abstract Open source soft cores have reached a degree of maturity. You can find them in products as diverse as a Samsung set-top box, NXP's ZigBee chips and NASA's TechEdSat. In this article we'll look at some of the more widely used: the OpenRISC 1000 from OpenCores, Gaisler's LEON family, Lattice Semiconductor's LM32 and Oracle's OpenSPARC, as well as more bleeding edge research designs such as BERI and CHERI from Cambridge University Computer Laboratory. We'll consider the technology, the business case, the engineering risks, and the licensing challenges of using such designs. What do we mean by “free” “Free” is an overloaded term in English. It can mean something you don't pay for, as in “this beer is free”. But it can also mean freedom, as in “you are free to share this article”. It is this latter sense that is central when we talk about free software or hardware designs. Of course such software or hardware designs may also be free, in the sense that you don't have to pay for them, but that is secondary. “Free” software in this sense has been around for a very long time. Explicitly since 1993 and Richard Stallman's GNU Manifesto, but implicitly since the first software was written and shared with colleagues and friends. That freedom is achieved by making the source code available, so others can modify the program, hence the more recent alternative name “open source”, but it is freedom that remains the key concept. -
Openpiton: an Open Source Manycore Research Framework
OpenPiton: An Open Source Manycore Research Framework Jonathan Balkind Michael McKeown Yaosheng Fu Tri Nguyen Yanqi Zhou Alexey Lavrov Mohammad Shahrad Adi Fuchs Samuel Payne ∗ Xiaohua Liang Matthew Matl David Wentzlaff Princeton University fjbalkind,mmckeown,yfu,trin,yanqiz,alavrov,mshahrad,[email protected], [email protected], fxiaohua,mmatl,[email protected] Abstract chipset Industry is building larger, more complex, manycore proces- sors on the back of strong institutional knowledge, but aca- demic projects face difficulties in replicating that scale. To Tile alleviate these difficulties and to develop and share knowl- edge, the community needs open architecture frameworks for simulation, synthesis, and software exploration which Chip support extensibility, scalability, and configurability, along- side an established base of verification tools and supported software. In this paper we present OpenPiton, an open source framework for building scalable architecture research proto- types from 1 core to 500 million cores. OpenPiton is the world’s first open source, general-purpose, multithreaded manycore processor and framework. OpenPiton leverages the industry hardened OpenSPARC T1 core with modifica- Figure 1: OpenPiton Architecture.
