Reoptimize design

At this point, the timing violations, if any, should be fixed by performing in place optimization on the design using the reoptimize design -ipo command as discussed in section 6.5. 

Perform in-place optimization, (reoptimize design -in placc -map cffort high)... 

Even in the best designed systems, reoptimization is unavoidable, but it is best to limit reoptimization to problems truly related to scale. 

Materials and Chemistry. The assessed database has been designed for use within the composition space associated with the SoG-Si materials. Among the 35 binary silicon-containing systems, the Si-Al, Si-As, Si-B, Si-C, Si-Fe, Si-N, Si-O, Si-P, Si-S, Si-Sb, and Si-Te systems have thermodynamically been reoptimized, primarily based on the assessed experimental information. Since thermodynamic calculations for the impurities in SoG-Si feedstock are normally multidimensional in nature, Gibbs energies of other 36 binary systems have also included in the database. 

In this section we compare the steady-state design and the dynamic control of heat-integrated extractive and pressure-swing processes. The same numbers of trays used in the base-case designs are used in both systems. The systems have not been reoptimized for heat integration. Only partial heat integration is considered in which an auxiliary reboiler is used. 

The implication of this study is clear If a delicate composite of matched components is modified by adding a new agent, then the design must be reoptimized. This may be difficult if a natural material such as clay is added, the properties of which may vary. Politically, one should consider extending the time line for such projects from 3 to 6 years. Then there would be a chance to design an improved product.
