There is a new blog post on the Intel Developer Zone on how we used Simics virtual platforms for the new Intel® Atom® P5900 series of system-on-chip (previously known as Snow Ridge). It talks about how shift-left works both inside of Intel and with our customers for the new chip, and the kinds of virtual platform models you use for different types of use cases.
