Breker security tables

It might seem paradoxical that simulation (or equivalent dynamic methods) might be one of the best ways to run security checks. Checking security is a problem where you need to find rare corners that a hacker might exploit. In dynamic verification, no matter how much we test we know we’re not going to cover all corners, so how can it… Read More

RISC-V

RISC-V is obviously making progress. Independent of licensee signups and new technical offerings, the simple fact that Arm is responding – in fundamental changes to their licensing model and in allowing custom user extensions to the instruction set – is proof enough that they see a real competitive threat from RISC-V.

Which all… Read More

When PSS comes up, a lot of mainstream verification engineers are apt to get nervous. They worry that just as they’re starting to get the hang of UVM, the ivory tower types are changing the rules of dynamic verification again and that they’ll have to reboot all that hard-won UVM learning to a new language. The PSS community and tool … Read More
