Filed:

Apr 4, 2003

Appl. No.:

10/408205

Inventors:

Travis Alister Bradfield - Colorado Springs CO, US
Tracy Robert Spitler - Colorado Springs CO, US
Gregory A. Johnson - Colorado Springs CO, US
Matthew Richard Motiff - Colorado Springs CO, US

Assignee:

LSI Logic Corporation - Milpitas CA

International Classification:

G06F017/50
G06F009/45

US Classification:

716 1, 716 6, 716 9, 716 10

Abstract:

A system and method for implementing logic changes in integrated circuits (ICs). In a preferred embodiment, donor logic elements are taken from donator logic paths. The donated cells are implemented into a logic path altered by an ECO. The donated cell is replaced by spare cells. Timing analysis is done to ensure all logic paths are timing closed.

Tracy R. Spitler - Colorado Springs CO, US

Assignee:

LSI Corporation - Milpitas CA

International Classification:

H03B 1/00

US Classification:

327552

Abstract:

An apparatus and method for filtering glitches in data signals are provided. The apparatus and method provide a programmable glitch filter that may be programmed to filter glitches of different depths. The apparatus and method further provide a glitch filter that is programmable and incorporates a synchronizer for synchronizing the filtered output from the glitch filter to a different clock domain than that of the clock input.
