System-Level Verification Tackles New Role
By Brian Bailey - 28 Apr, 2016 - Comments: 0

Wally Rhines, chairman and CEO of Mentor Graphics, gave the keynote at DVCon this year. He said that if you pull together a bunch of pre-verified IP blocks, it does not change the verification problem at the system level. That sounds like a problem. There are assumptions made that the IP blocks work to a reasonable degree, and that when performing system-level verification the focus is not a... » read more

Formal Verification Applied To The Renesas MCU Design Platform Using OneSpin Tools
By OneSpin Solutions - 27 Apr, 2016 - Comments: 0

An effective measure of verification progress, together with guidance towards design areas remaining untested, requires a precise view of the test coverage achieved. To risk signing off the verification process without understanding the quality of testing raises the specter of post-production device bugs. OneSpin Solution’s patented Quantify technology employs Observation Coverage, which eval... » read more

Debug: Last Bastion Of Automation
By Brian Bailey - 27 Jan, 2016 - Comments: 0

There have been a number of times when anecdotal evidence became folk law and then over time, the effort was put in to find out whether there was any truth in it. Perhaps the most famous case is the statement that verification consumes 70% of development time and resources. For years this “fact” was used in almost every verification presentation and yet nobody knew where the number had come... » read more

Defining Sufficient Coverage

IP Verification Challenges
By Brian Bailey - 30 Jul, 2015 - Comments: 0

At the Design Automation Conference this year, the Designer and IP tracks were the stars of the show in many ways. These sessions catered to industry rather than academia and provided engineers with information they could directly use in their jobs. Many of the sessions were filled to capacity and Anne Cirkel, general chair for the 52nd DAC, was enthusiastic about the growing success of these t... » read more

Full Coverage Or Full Monty
By Brian Bailey - 22 Jun, 2015 - Comments: 0

Without adequate coverage metrics and tools, verification engineers would never be able to answer the proverbial question: are we done yet? But a lot has changed in the design flow since the existing set of metrics was defined. Does it still ensure that the right things get verified, that time is not wasted on things deemed unimportant or a duplication of effort, and can it handle today’s hie... » read more
