SoC and IP: My Love-Hate Relationship with Mobile World Congress

PaulaJones
My friends are jealous. I get an all-expense-paid trip to Barcelona, Spain to see the latest and greatest mobile technology at Mobile World Congress (MWC). They don't believe it when I tell them I love the yearly trips to Barcelona, but also hate it.
What I love about Barcelona and MWC:
Staying in the Gothic quarter, with all the good food and entertainment.
The nice busses we rent that take us directly to and from the…

Verification: Covering Edges (part II)—“Inverse Normal” Distribution

teamspecman

In the previous example, we used the "select edge" to generate edge values for fields. But in many cases, what you really want to generate is not the exact edge, but "near the edges". For example, for a field of type uint (bits : 24), generate many items whose values are 0..4, and many of 0xfffff0..0xffffff. To achieve this, you can call this "the inverse normal distribution" and give more weight to the edges.…
