Although the problem of fault collapsing is not considered to be too complex, the time of collapsing faults in large circuits can be several hours or more. Large circuits are efficiently described using hierarchy, which significantly helps the architectural design, verification and physical design. We add fault collapsing to that list. We do not flatten the circuit and the collapsed fault sets ...

We discuss the advantage of using hierarchy in testing. Our demonstration is based on the problem of fault collapsing. Though this problem is not considered to be too complex, the time of collapsing faults in moderately large circuits can be several hours or more. This can be considerably shortened by hierarchical fault collapsing. Large circuits are efficiently described using hierarchy, which...

Collapsing glomerulopathy is an aggressive morphologic variant of focal segmental glomerulosclerosis which typically presents with nephrotic syndrome and rapidly progressive renal failure. Most cases of collapsing glomerulopathy are associated with human immunodeficiency virus infection. We present a rare case of collapsing glomerulopathy associated with acute cytomegalovirus (CMV) infection in...

A description in the Jacobs and Langen domain is a set of sharing groups where each sharing group is a set of program variables. The presence of a sharing group in a description indicates that all the variables in the group can be bound to terms that contain a common variable. The expressiveness of the domain, alas, is compromised by its intractability. Not only are descriptions potentially exp...

We define what it means for a function on ω1 to be a collapsing function for λ and show that if there exists a collapsing function for (21), then there is no precipitous ideal on ω1. We show that a collapsing function for ω2 can be added by forcing. We define what it means to be a weakly ω1-Erdös cardinal and show that in L[E], there is a collapsing function for λ iff λ is less than the least w...
