Post-silicon debug is the problem of determining what's wrong when the fabricated chip of a
new design behaves incorrectly. This problem now consumes over half of the overall …

Hardware redundancy is a common method for improving the reliability of a system. The
disadvantage of this approach is the hardware overhead and the additional power …

Certain embodiments of the present invention are configured to permit development and
validation of a device driver or a device application program by using improved virtual …

Virtual prototypes are increasingly used in device/driver co-development and co-validation
to enable early driver development and reduce product time-to-market. However, drivers …

Computer systems, such as Smartphones, personal digital assistants, tablets, netbooks,
laptops, and desktops, typically include a processor, communication unit such as a bus …

Triple modular redundancy (TMR) is a common method to implement fault-tolerant circuits.
Traditionally, TMR is realized by triplication of components. In order to reduce the area …

Presents a comparison of superscalar and decoupled access/execute architectures. Both
architectures attempt to exploit instruction-level parallelism by issuing multiple instructions …

Assertions in silicon help post-silicon debug by providing observability of internal properties
within a system which are otherwise hard to observe. Besides generating synthesizable …

This paper presents a post-silicon debug methodology that provides a means to rewind, or
backspace, a chip from a known crash state using a combination of on-chip real-time data …

Virtual prototypes of hardware devices, aka, virtual devices, are increasingly used to enable
early software development before silicon prototypes/devices are available. In previous …
