Filed:

Mar 29, 2002

Appl. No.:

10/112803

Inventors:

Richard Price - San Jose CA

Assignee:

Altera Corporation - San Jose CA

International Classification:

G11C 700

US Classification:

365201, 36518902, 36523003, 365233, 326 38, 326 40, 326 41

Abstract:

In a mask-programmable logic device having embedded memory blocks, which device cannot be reconfigured for testing like a full programmable logic device, the embedded memory blocks are tested by forming scan chains from the input-side registers of a plurality of embedded memory blocks, and from the output-side registers of a those embedded memory blocks. Test vectors are clocked into the input-side scan chain and the results are clocked out from the output-side scan chain. The test vectors can be made by concatenating multiple copies of a test vector for one block when the blocks are identical. The method works even where one or more embedded memory blocks are configured as read-only devices, as long as the contents of the read-only devices are known so that one knows what test output to expect.

International Classification:

US Classification:

Abstract:

Method and apparatus for imaging at multiple perspectives of a specimen are disclosed. In one embodiment, an apparatus for generating a multi-perspective image using multiple charged particle beams (e. g. , electron beams) is disclosed. In one embodiment, the apparatus generally includes a charged particle beam generator system arranged to generate and control a first charged particle beam directed substantially at a first angle towards the specimen and a second charged particle beam directed substantially at a second angle towards the specimen. The apparatus also includes an image generator arranged to generate one or more images based on charged particles emitted from the specimen in response to the first and second charged particle beams and a controller arranged to cause the charged particle beam generator to direct both the first charged particle beam and the second charged particle beam at a first area of the specimen. In a specific implementation, the charged particles are in the form of electrons and the apparatus is a dual electron beam scanning electron microscope (SEM).

International Classification:

US Classification:

716 17, 716 18

Abstract:

A user logic design for a mask-programmable logic device (“MPLD”) may be designed on a comparable or compatible user-programmable logic device (“UPLD”) and migrated to the MPLD, or may be designed directly on an MPLD. If the design is designed on a UPLD, the constraints of the target MPLD—i. e. , differences between the devices—are taken into account so that the migration will be successful. If the design is designed directly on an MPLD, constraints of a comparable compatible UPLD are taken into account if the user indicates that the design will be migrated to the UPLD for testing. This means that when a logic design is intended to be migrated back-and-forth between a UPLD and an MPLD, only the intersection of features can be used. To facilitate migration, fixed mappings between pairs of devices may be created.

International Classification:

C08C 2100
B42D 100

US Classification:

178 18

Abstract:

The present invention provides novel methods, forms and devices for simultaneously capturing handwriting on one or more forms and on an electronic device including a membrane digitizer, wherein the forms are integrated with the digitizer. Proper alignment between the digitizer surface and a business form placed on the digitizer surface is electronically checked. The form is removably affixed to the digitizer by means of an adhesive.
