Appl. No.:

09/946857

Inventors:

Ajay Khoche - Cupertino CA, US
Jochen Rivoir - Magstadt, DE
David H. Armstrong - Boulder CO, US

Assignee:

Verigg IPco - Singapore

International Classification:

G01R 31/28

US Classification:

714726

Abstract:

An integrated circuit, including a configurable scan architecture used for an integrated circuit test procedure and quality control. The configurable scan chain architecture has the capability of being reconfigured to one of a variety scan chain architectures based on the constraints of the integrated circuit and the testing device. The present invention minimizes the integrated circuit test time by reconfiguring the scan architecture depending on certain constraints such as the latching frequency, the predetermined I/O frequency, the number of available integrated circuit I/O pins, the number of pins required for a proposed scan architecture, and the number of available pins on the testing device. The configurable scan architecture receives configuration signals which indicate which scan chain architecture should be configured on the integrated circuit that is being tested.

International Classification:

G01R 31/28

US Classification:

714732, 714735

Abstract:

Pattern controllable LFSRs or MISRs are disclosed that are able to mask indeterminate states while performing tests on DUT outputs. At appropriate times, the MISRs or the LFSRs will mask the data being input to the MISRs or the LFSRs so that indeterminate states are not received. This allows fast/complex ATE Rx memory to be replaced by slower and smaller MISR pattern memory. At the end of a test period, the LFSRs or MISRs generate signatures which are then compared to a set of possible valid signatures for non-deterministic data. A pass/fail result is produced. By masking indeterminate states, fewer valid signatures need to be stored. Masking of the MISRs or LFSRs may be based on the fact that indeterminate states and good data in a serial output data stream tend to occur in predictable patterns, or that good data may follow alignment characters. MISR or LFSR output signatures may also be employed to test individual pattern segments instead of the entire input test pattern. This expected DUT Rx data compression implementation works for one signature (deterministic) data as well.

US Classification:

602 28, 602 16, 602 23, 128882

Abstract:

Orthopedic device for treating neuropathic ulcers and other injuries while allowing easy access to the wound site on the plantar surface of a patient's foot includes a base portion and a sole that is either movably connected or removably connected to either the base or to a strut member. The base or strut is maintained in position on the lower leg while the sole may be rotated, slid, or completely removed for allowing inspection and access to the plantar surface of the patient's foot.

Abstract:

A system for making a cementitious composite includes a cementitious material supply system for dispensing a powdered cementitious material or a semi-powdered cementitious material into a receiving material. The receiving material includes a structural layer and a sealing layer. The structural layer includes an open continuous volume extending from a first side to a second side opposite the first side. The sealing layer is coupled to the first side. The cementitious material supply system is configured to dispense the powdered cementitious material or the semi-powdered cementitious material into the open continuous volume to fill the open continuous volume.
