Optimizing The Data Center With PCI Express 4.0


PCI Express (Peripheral Component Interconnect Express), also known as PCIe, is a high-speed serial computer expansion bus standard designed to replace older PCI, PCI-X and AGP bus standards. Officially launched in 2003, PCIe was rapidly adopted by chip, system and software designers and emerged as the dominant interface standard for connecting peripherals to the CPU. Modern CPUs rely on the... » read more

The Week In Review: Design


Tools Mentor added new tools to its high-level synthesis portfolio. The DesignChecks tool helps find bugs during coding with a static mode that performs very fast linting-like checks of the code and a formal mode that uses a formal engine for a more exhaustive proof of issues. The synthesis-aware Coverage tool measures code coverage for C++ signoff and fast closure of synthesized RTL. It sup... » read more
