that one optical detector is rendered defective after manufacturing. Thus, the
operations assigned to this detector have to be remapped to other detectors.
The modified synthesis method proposed in Section 2.3.1 is used here to carry
out the reconfiguration so that these manufacturing defects are tolerated. The
reconfiguration results are shown in Figure 2.10b. This new design allows the
protein assay to operate on this defective biochip with an increase of only 7%
in the completion time; that is, the completion time is now 387 s.
2.4.3 results for Presynthesis Defect Tolerance
We next evaluate the presynthesis defect tolerance that is achieved for
the protein assay using the enhanced routing-aware method described
in Section 2.3.2. We first use this method to find a desirable solution that
