Incorporating Physical Design-for-Test into Routing

چکیده
In addition to automatically generating correct wiring, routers are used to meet additional design goals. Examples include reducing capacitive coupling and improving yield. Using routers to improve testa-bility has been mentioned in the literature, but concrete rules or methods have not been explained or implemented. In this paper, we show how a modiied router improves bridge fault testability for two diier-ent test metrics, static-voltage testing and pseudo-exhaustive segmentation testing, with no signiicant increase in area or time. This method is exible in that further testability improvements are possible by trading oo area or routing time.

Routing tools consume a signiicant portion of the total design time. Considering routability at earlier steps of the CAD ow would both yield better quality and faster design process. In this paper we are presenting a routability-driven clustering method for cluster-based FPGAs. Our method packs LUTs into logic clusters while incorporating routability metrics into a cost function. The objective ...
متن کاملA Multiple-objective based Hierarchical Global Routing Approach for VLSI ASIC Design
A VLSI chip can today contain hundreds of millions transistors and is expected to contain more than 1 billion transistors in the next decade. In order to handle this rapid growth in integration technology, the design procedure is therefore divided into a sequence of design steps. Circuit layout is the design step in which a physical realization of a circuit is obtained from its functional descr...
