Abstract

We present a simulator for evaluating the redundancy analysis (RA) algorithms. The simulator can calculate the repair rate (the ratio of the number of repaired memories to the number of defective memories) of the given RA algorithm and the associated memory configuration and redundancy structure. With the tool, the user also can easily assess and plan the redundant (spare) elements, and subsequently develop the built-in redundancy analysis (BIRA) algorithms and circuits that are essential for built-in self-repair (BISR) of embedded memories.The simulator has another important feature — it can simulate the sequence of the detected faults in the real order, improving the accuracy of the analysis results.
