A new approach is presented for the reconfiguration of VLSI tree architectures. It is based on a process of logical displacement for accomplishing reconfiguration with the global availability of redundant cells (or spares). A new and simple switch structure is proposed which allows flexibity in routing and spare allocation to accomplish a double displacement in the reconfiguration process. The proposed switch structure also permits a fully global execution of the reconfiguration process as the reconfigured tree spans the whole structure, not only a subtree as in previous approaches. Overhead issues with respect to the number of spares and redundant links are addressed. The conditions for reconfigurability are fully analysed; it is proved that the ability to reconfigure in the presence of a double displacement results in an improvement in reconfigurability. Faults in basic cells, links and switching circuits are considered. A lower bound on the improvement of reconfigurability is established. Simulation results and illustrative examples are also presented. |
