Appl. No.:

10/132587

Inventors:

Michael Y. Chen - Lake Oswego OR 97035
Michael C. Brouhard - Lake Oswego OR 97034
John Wilson - Wokingham R940 4TZ, GB

International Classification:

G06F 1750

US Classification:

716 12, 716 1, 716 5, 716 3

Abstract:

An IP package is formed with at least one of one or more components of an IP block and one or more pointers to locations where the components can be retrieved, and machine readable connectivity descriptions describing how the IP block is to be connected to include the IP block in an integrated circuit. In one embodiment, the connectivity descriptions include physical pin, implemented bus signals, handling of unimplemented bus signals, and mapping descriptions. In various embodiments, the IP package may further include one or more selected ones of customizable attribute, UI choice elements, embedded and/or diagnostic software, test vectors, supplemental generators and verification environment configuration requirement descriptions. The self-describing packaging advantageously enables an EDA tool suite to offer and facilitate selection of the IP block for a SOC design.

John Wilson - Wokingham, GB

International Classification:

G06F017/50

US Classification:

716/005000

Abstract:

An EDA tool suite is equipped with the ability to responsively invoke a chain of one or more generators corresponding to one or more phases of a design/verification process to process design information of IP blocks forming a SOC design to transform the design information, as a result of each invocation, from one state to another state. In one embodiment, the phases may be one or more of a design generation phase, a simulation hardware logic generation phase, an embedded/diagnostic software generation phase, and a verification environment configuration script generation phase.

International Classification:

G06F017/50

US Classification:

716/005000

Abstract:

Enhanced Platform Based SOC Design Including Extended Peripheral Selection and Automated IP Customization Facilitation An EDA tool suite is provided to facilitate SOC design in a platform based manner, by first facilitating the selection of a compute engine, then supporting peripheral devices layered upon the compute engine in at least a single peripheral layer. In various embodiments, the EDA tool suite includes pre-processing functions to identify connectivity of an IP component, and automatic creation of a user interface to facilitate provision of customization inputs. The EDA tool suite further includes bus bridges bridging a plurality of bus architecture pairs, and component selection facilities that automatically provides an expanded list of components for selection, including components connectable to a selected compute engine by way of a pre-provided bus bridge, responsive to the selection of the compute engine.

Inventors:

- Wilsonville OR, US
Eugene Kishinevsky - Portland OR, US
Michael Chen - Happy Valley OR, US

International Classification:

G06F 21/71
G06F 21/76

Abstract:

This application discloses an electronic system including active circuitry configured to be selectively enabled for authorized number of times. The electronic system also includes security circuitry to detect an enablement event associated with the electronic system. The enablement event can correspond to reception of a reset signal associated with the electronic system, a lapse of a predetermined time period, or the like. In response to the detection of the enablement event, the security circuitry can determine a number of times the security circuitry has previously enabled the active circuitry. The security circuitry can generate the enablement signals capable of enabling the active circuitry when the determined number of times the security circuitry has previously enabled the active circuitry is fewer than the authorized number of times.

International Classification:

G06F 21/75
G06F 21/76

Abstract:

This application discloses a physical unclonable function device including physical unclonable function units, each capable of generating an output. The physical unclonable function device can extract bits from the outputs at various inspection locations and utilize the extracted bits to generate an identifier for the physical unclonable function device. An inspection configuration tool can identify the inspection locations and configure the physical unclonable function device with the inspection locations. The inspection configuration tool can sample the physical unclonable function circuitry to identify a plurality of multi-bit outputs, select bit locations in the multi-bit outputs as inspection locations based on bit value stability for the bit locations, and configure the identifier generation circuitry in physical unclonable function device with the inspection locations.

International Classification:

H04L 9/32
H04L 9/10

Abstract:

This application discloses a physical unclonable function device including physical unclonable function units, each capable of generating an output. The physical unclonable function device can utilize transforms to derive bits from the outputs and utilize the derived bits to generate an identifier for the physical unclonable function device. An inspection configuration tool can sample multiple outputs from each of the physical unclonable function units, identify a transforms to perform on a future output for each of the physical unclonable function units based on a distribution of values corresponding to the sampled outputs. The inspection configuration tool can configure the physical unclonable function device to perform the transforms on the future outputs of the physical unclonable function units. Embodiments will be described below in greater detail.
