Q1-2012 - Aldec™ Design and Verification NewsletterDate: 2012/01/19 Type: Newsletter Looking Back – and Ahead to the Next 30 Years Two years from now, Aldec will celebrate a milestone - 30 years of innovative service to the Electronic Design Automation industry. Working with designers in the field since the birth of EDA, Aldec has had a front row seat to witness the recent decades’ astonishing surge in technology. From smart phones to advances in medical safety and aviation, few outside the industry realize without the diligent electronics designer aided in the lab by innovative EDA tools - the life changing advances we take for granted today would not exist. Fewer EDA tool providers competing for their business (thanks to a steady stream of recent mergers and acquisitions) has left some customers asking if the future of EDA will hold less innovation, support and service – at a higher price. At Aldec, our customer-centric business model ensures that we will continue to revolutionize the industry with exciting tools delivered to serve real-world needs of our customers.

OS-VVM™ named Product of the Week by Electronics World for Delivering Randomization Capabilities to VHDL Designers Open Source - VHDL Verification Methodology (OS-VVM™), recently named Electronics World Product of the Week, delivers advanced verification test methodologies, including Constrained and Coverage-driven Randomization, as well as Functional Coverage, providing advanced features to VHDL design engineers while enabling them to continue to develop using VHDL. Read More Benefits of OS-VVM It provides access to advanced randomization and functional coverage capabilities (previously available only within system-level methodologies) that can be used in any testbench; Rather than using a constraint solver, balance in the randomization is achieved by interacting with the functional coverage model, resulting in fewer cycles; The initial randomization is refined by using procedural code which can easily mix directed, algorithmic, file-based methods and additional randomization; and A straightforward usage model, ensuring users are able to get up to speed quickly while retaining the freedom and flexibility to continue using VHDL. Availability Aldec tools offer the advanced randomization and functional coverage capabilities provided by OS-VVM with a simple flip of the VHDL-2008 switch; i.e.no additional licenses are required. SynthWorks, the maintainer of the OS-VVM, offers in-depth training for OS-VVM and supplements with additional packages for creating scoreboards, memories, and abstracting interfaces.

Hardware Visibility-based Debugging (HVD™) Technology, Provides 100% Visibility During Hardware Emulation Built into the emulation solution, Aldec’s HVD (Hardware Visibility-based Debugging) technology analyzes RTL code to identify the minimal set of debugging probes that must be present in the emulation hardware to guarantee 100% visibility. During the emulation runtime, the HVD based data extender calculates any design probes that have not been captured directly from the emulator. For a typical SoC design, this reduces the amount of data required to be preserved and captured from the emulator to 30% (70% saving). Additionally, both dynamic and static probes from emulation can be visualized in the Riviera-PRO waveform viewer preserving the original signal names and hierarchy paths and complete traceability to the designs RTL source code. Read More Until now, hardware designers were forced to use multiple applications in addition to their simulator and emulator to ensure proper hardware signal data extraction and visualization. With HVD technology, Aldec facilitates a fully integrated debugging solution with improved functionality and simplified debugging flow. Designers will be able to use the familiar debugging features of Riviera-PRO during emulation and eliminate the unnecessary steps of database conversion.

Advanced Standalone Reporting to Facilitate Design Reviews With the latest release of ALINT, product version 2012.01, even completely new users can create and distribute interactive reports in a few minutes without the knowledge of any details about the design that is being checked, tool’s configuration, commands, and command line switches. Typically it takes less than one hour to set up and check a relatively complex design and deploy the appropriate interactive report on the corporate intranet or version control system. Read More The new Standalone Reporting feature enables completely independent reports that can be viewed with any standard web browser at any computer, with no additional ALINT license required. These new Standalone reports include just everything you would expect from a dedicated feature-rich GUI application, including the tools for navigation through the design hierarchy, coding standard violations analysis, and cross-probing from the violation reports to the source files for quick investigation, thus providing a complete insight into the quality of design at the current point of development cycle. For more, please visit www.aldec.com/en/products/functional_verification/alint-pro. Standardized Coverage Driven Verification Do you think that vendor specific coverage database format is not sufficient when it comes to overall coverage driven verification? Coverage metrics can come from different sources such as simulation, formal verification, equivalence checking, static design checking etc. There are different vendors that provide tools/solution for each of these categories. But each vendor has their own proprietary coverage database format which keeps users from mixing verification management tool and simulator from different vendors in their flow. Read More Accellera has been working on Unified Coverage Interoperability Standard (UCIS) which will facilitate the portability across multiple vendors and enable the innovation for the next generation of coverage tools. Additional benefits of UCIS compliance coverage database: It can store coverage data from the entire simulation or a snapshot made at any moment of the simulation process Merges coverage data from multiple simulation runs into a cumulative database (temporal, spatial, and heterogeneous use cases) API that allows transferring coverage data between different vendors Aldec.com delivers New Features and Enhanced User Functionality Aldec.com has a new look, fresh content, new features and enhanced functionality.

Did You Know?The Signal Alias Editor in Active-HDL™ allows you to assign your own easy-to-recognize design mnemonics to real values of signals displayed in the Memory or Waveform Viewer windows. Waveform Viewer is now also able to represent vectors as a fixed-point numbers.Preference Manager inside Active-HDL™ allows you to export and import the tool preferences. Now, tool settings can be retained when you move between the versions. Tool preferences from previous version can be exported to a file which later using preference manager can be imported back to the new version. Preference Manager can be invoked by executing the prefman.exe file located in the \Bin sub-directory of Active-HDL installation folder.Code Templates integrated with Riviera-PRO HDL Editor enable you to define custom code templates with auto-complete mnemonics and variable fields (the variable-based templates enable quick change of special fields that occur multiple times within a code template – while editing a first occurrence of a variable field, the other occurrences of this field are updated automatically). Once the templates are saved to an .xml file, they can be shared across your company to facilitate code editing and standardization.You can use the built-in classifications (such as "differences between the RTL and post-synthesis simulation" or "synchronous reset guidelines") to address the violations related to a particular part of your coding standard. To do that, you just need to drag-and-drop the appropriate subset/branch from Rule Plug-in Viewer to the Violation Viewer. This adds a quick auto-filter and enables you to focus on the topic of your concern.
