Welcome to the SpringSoft Technology Newsletter. This is a monthly e-mail newsletter distributed to our customers, partners, and friends to provide information on our Novas Verification Enhancement and Laker Custom IC Design technologies. We hope the information in this newsletter will help you to use our products more effectively in your design and verification environments.
Please see the links at the end of this newsletter for subscription information or to provide feedback that will help us improve future editions.
Automatically Compress Dump-off Regions
The Verdi system provides the fsdbDumpon/fsdbDumpoff dump commands to turn off FSDB dumping for a specific time range. The dump-off region will be shown as blue in the waveform view, so that users don't need to pay attention to these no-value regions. Starting from the Novas 2009.10 release, this capability has been combined with the Compress Time Range feature.
Automatically Adjust the Height for Messages/Transactions
The Verdi system supports viewing of transactions/messages in the waveform view; however, some transactions/messages may contain lots of attributes which makes the browsing of all these attributes inconvenient - in previous Verdi versions, users needed to adjust the height manually or view all attributes in the tip window.
IC Design Tips:
Forward And Backward Compatibility
Software is considered backward (or downward) compatible if newer versions or releases can read, view, and operate on data that was created with prior versions or releases. This should not be confused with forward compatible which means that older software can read, view, and operate on data that has been created with newer releases. Most design automation software is backward compatible.
Stretching and Abutment of PCells
Stretch handles provide a means to graphically stretch and re-size shapes in PCell layout. They are defined within the source code for the PCell. This graphical stretching operation causes the associated parameter value to change, and the PCell code is then re-evaluated to create the corresponding submaster.
Introducing Functional Qualification
Functional verification consumes a significant portion of the time and resources devoted to the typical design project. As chips continue to grow in size and complexity, designers must increasingly rely on a dedicated verification team to ensure that systems fully meet their specifications. Verification engineers have at their disposal a set of dedicated tools and methodologies for verification automation and quality improvement. In spite of this, functional logic errors remain a significant cause of project delays and re-spins.
SoC Verification Challenges: Adopt Checker Quality Metric to Guard IP Quality - Techguri, Oct, 2008
As pointed out in the previous post, a not-well-verified IP can be a major killer for any SoC project. SoC integrators basically don't have the time or resources to debug individual problematic IPs. A bad IP can really delay a project, if not kill it.
Having a robust IP signoff process is really critical and adopting reliable signoff metrics to help make signoff decisions is key.
All Worldwide Support Consolidated To One Site
No matter where you are worldwide, you can now find SpringSoft's top rated support in one place. Just go to http://support.springsoft.com
A new Novas 2009.10 version, which unifies the VerdiTM Automated Debug System and the SilotiTM Visibility Automation System from a use-model and packaging point of view, was released in October as the default product installation package for Springsoft Novas Debug Solutions, including Verdi and Siloti.
These refinements make it easier and more natural for both Siloti and Verdi users. Users will now be able to access Siloti features through the familiar Verdi interface rather than having to go outside the Verdi flow to prepare and set up for Siloti's unique data expansion capabilities. These improvements will have no impact on licensing.
Novas (Verdi/Siloti): Current release - 2009.10
Laker: Current release - 2009.9 (v5)
Certitude: Current release - 2.7
Voting Opens in SpringSoft Superhero Story Contest
SAN JOSE, Calif. - SpringSoft, Inc., a global supplier of specialized IC design software, has chosen five finalists and has opened online voting to the EDA community to decide a winner in its superhero story contest. The contest highlights extraordinary engineering efforts that made a difference either in an engineer's personal life or at work. The winning story will be featured in a new version of the SpringSoft anime comic strip featured on the SpringSoft website.
Voting is open until November 13 at http://www.springsoft.com/superhero_comics/superhero-story-vote
22nd Synopsys EDA Interoperability Forum
November 5th - Sun Conference Center @ Agnews Historical Park
The tentative agenda for the IPL session is the following:

Engineering Superhero Corner:
Be An Engineering Superhero to the Global Community
SpringSoft is working with the Engineers Without Borders Labdoo Project to bring the excess supply of technology from our developed world to developing regions throughout the globe. At this year's DAC, we kicked off the program with a collection drive for used and unwanted laptops that will be refurbished and distributed to disadvantaged communities. We will continue to collect laptops on behalf of Engineers Without Borders Labdoo Project.
