New flops inserted in an ECO should be stitched into existing scan chains to avoid DFT coverage loss. A method of conserving power in ICs by powering down segments of a chip when they are not in use. The theory is that if the most critical timing paths can pass the tests, then all the other paths with longer slack times should have no timing problems. RF SOI is the RF version of silicon-on-insulator (SOI) technology. From timing point of view, higher shift frequency should not be an issue because the shift path essentially comprises of direct connection from the output of the preceding flop to the scan-input of the succeeding flop and therefore setup timing check would always be relaxed.
