US Patent:
7000163, Feb 14, 2006
Filed:
Feb 25, 2002
Appl. No.:
10/082737
Inventors:
Juergen Dirks - Santa Clara CA, US
Juergen K. Lahner - Sunnyvale CA, US
Ludger F. Johanterwage - Los Gatos CA, US
Benjamin Mbouombouo - San Jose CA, US

Assignee:
LSI Logic Corporation - Milpitas CA
International Classification:
G01R 31/28
US Classification:
714727, 716 1, 703 19, 438 18, 324763
Abstract:
An apparatus comprising one or more groups of boundary scan cells, one or more group buffers, one or more repeater buffers and a controller. The group buffers may be coupled to each of the groups of boundary scan cells. The repeater buffers may be coupled in series with the group buffers. The controller may be coupled to the groups of boundary scan cells through the group buffers and the repeater buffers. The apparatus may be configured to buffer the groups of boundary scan cells to reflect an order of I/Os around the apparatus.

US Patent:
57712670, Jun 23, 1998
Filed:
Oct 8, 1996
Appl. No.:
8/727257
Inventors:
Stefan Graef - Milpitas CA
Ludger Johanterwage - San Jose CA
Assignee:
LSI Logic Corporation - Milpitas CA
International Classification:
G07C 302
US Classification:
377 16
Abstract:
According to the present invention, the invention relates to a semiconductor device having an activity monitor circuit formed thereon for monitoring the switching activity of signals generated by other circuits on the device during burn-in testing. In one embodiment, the activity monitor circuit includes means for detecting a present state of a signal; means for comparing the present state with a previous state of the signal; means for determining whether the state of the signal has switched a requisite number of times in a predetermined time period; and means for displaying the results of the determination.
