When are we done?

This reminds me of the issues in software test. There's no clear time to "blow the whistle and we're done" anymore. It is a bit scary. Especially with mission critical apps.

Application Specific Static Formal Verification is Making the Difference

NO RATINGS
At the Design and Verification Conference last February, there was a panel ("Where Does Design End and Verification Begin?") that discussed the impact of new verification tools that focus on just one problem area and thereby enable more effective verifcation.  Engineers no longer have to create a solution out of their own dynamic simulator, static analyzer, or ABV tools.   

In the example of Meridian clock-domain-crossing (CDC) verification,  a mix of structural, formal and dynamic methods operating under-the-hood, ensure that an SoC will not fail with a metastability issue.   Other examples are state-of-the art Lint analysis, and X-propagation and reset verfication / optimization.

At Real Intent, we call this new category Static Verfication.   Gary Smith calls them Verification Apps. I see these as important addition to our tool chest so engineers don't design SoCs that we cannot verify.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
