Reed-Solomon Compiler v3.4.0 readme.txt This readme file for the Reed-Solomon Compiler includes information that was not incorporated into the Reed-Solomon Compiler User Guide v3.4.0. Before installing the compiler, ensure you have read the information in this readme.txt. This file contains the following information: o Package Contents o Tool Requirements o MegaCore Function Directory Names o Project Name & Top-Level Entity Name o MegaWizard Plug-In Manager Copy Function o Preliminary Support for Lower Number of Check Symbols o ModelSim Simulation Models o Regenerating the Reed-Solomon Library o Release History o Contacting Altera Package Contents ================ Reed-Solomon Compiler v3.4.0 Reed-Solomon Compiler User Guide v3.4.0 Tool Requirements ================= This compiler requires the following software: o Quartus II software version 4.0 or higher o Adobe Acrobat Reader version 5.0 or higher, for viewing PDF documentation o Netscape Navigator version 4.7 or higher on computers running a supported version of the RedHat Linux or Solaris operating systems for following web links or viewing this readme within IP Toolbench MegaCore Function Directory Names ================================= The default directory for your MegaCore function is c:\megacore, but you can specify an alternative directory. Note: the directory name must not contain spaces, or the MegaWizard Plug-In will not work. Project Name & Top-Level Entity Name ==================================== If your Quartus II project does not have a revision with the same name as the project, the wizard cannot add to your project the files that are required by the MegaCore function. This situation can occur if you specify a different top-level entity name from the project name in the Quartus II New Project Wizard. Therefore, when you use the Quartus II New Project Wizard, use the same name for the project name and the top-level entity name, and a revision with the same name as the project is created automatically. If you have an existing project where there is not a revision with the same name as the project, follow these steps: 1) Open the project. 2) Choose Revisions (Project Menu). 3) Click Create. 4) Enter the original project name in the revision name box. 5) Turn off Set as Current Revision. 6) Click OK and click Close. MegaWizard Plug-In Manager Copy Function ======================================== The MegaWizard Plug-In copy function does not work properly. If you select the "Copy an existing megafunction variation" on page 1 of the MegaWizard Plug-In Manager, IP Toolbench does not create a new variation based on the values specified by an existing variation, it creates a new variation based on default values. You may need to modify these values to suit your requirements. Preliminary Support for Lower Number of Check Symbols ===================================================== The standard continuous decoder incorporates preliminary support for two check symbols (the lower limit is usually 4 check symbols). Contact Altera if you wish to use this feature. ModelSim Simulation Models ========================== The ModelSim simulation models included with this MegaCore function may only be used with the ModelSim simulation tool version 5.7c and higher. If you are using a previous version of the ModelSim simulator, please download the latest version from: www.model.com (PE and SE versions) www.altera.com (ModelSim-Altera) Regenerating the Reed-Solomon Library ===================================== The VHDL model has been compiled using the ModelSim-Altera simulation tool version 5.7c. Depending on your current ModelSim version, you may need to regenerate the ReedS library before running a simulation. Check your ModelSim installation readme file to see whether you need an update. If so, the ReedS library can be refreshed by executing the following command: vcom -work \ReedS -force_refresh Please refer to your ModelSim user manual for further details. Release History ================ Version 3.4.0 ----------- Support for Stratix(TM) II devices. Support for IP toolbench. IP functional simulation models for use in Altera-supported VHDL and Verilog HDL simulators. No support for DSP Builder Software. Increased maximum frequency for standard continuous decoder. Version 3.3.5 ----------- Multiple version support for DSP modularity. Special version for DSP Kit. Version 3.3.4 ----------- Multiple version support for DSP modularity. Version 3.3.3 ----------- DSB Builder modularity fix Bug fix in file RS_std_cont_tb.vhd Version 3.3.2 ----------- DSB Builder modularity fix New device support added Version 3.3.1 ----------- DSP Builder modularity support. UNIX support. OpenCore Plus hardware evaluation support Version 3.3.0 ----------- Stratix device support. Use of separate lpm library removed; required models are in ReedS. Java MegaWizard Plug-In instead of C++. Version 3.2.0 ----------- Improvement on continuous decoder architecture full keysize yielding an increase in maximum frequency for large number of check symbols. VHDL model compiled with the ModelSim-Altera simulation tool. Visual IP models included with installation. Version 3.1.0 ----------- Bug fix on erasure-supporting continuous decoder Version 3.0.0 ----------- Product order codes simplified Reduction in size and increase in maximum frequency Version 2.1.0 ----------- Major improvements on continuous decoder architecture Version 2.0.0 ----------- Variable encoder introduced Continuous decoder introduced Variable decoder option introduced Version 1.0.0 ----------- Initial release Contacting Altera ================= Although we have made every effort to ensure that this version of the Reed- Solomon Compiler software works correctly, there may be problems that we have not encountered. If you have a question or problem that is not answered by the information provided in this readme file or the user guide, please contact your Altera Field Applications Engineer. If you have additional questions that are not answered in the documentation provided with this function, please contact Altera Applications: Technical Support Hotline: (800) 800-EPLD (U.S.) (408) 544-7000 (Internationally) World-Wide Web: www.altera.com/mysupport Last updated February, 2004 Copyright 2004 Altera Corporation.
