Web2. Then we need to modify the clocking architecture to add an On-chip Clock Controller(OCC) for every clock domain, as shown in Figure 4.We have six clock domains, thus six OCCs. As discussed here, the OCC … WebApr 27, 2012 · you define to the DFT tool, a capture/shift signal, this signal is RTL coded and directly controlled by a pad when the chip is in scan mode. so this signal is also check by STA. The dft tool connects this signals to all SE pin of flop and the output dft mux which select the scan chain out or the functional out on scan chain output pad.

WebJul 2, 2024 · Next we introduce the automatic fault classification of DFT instruments. Part 2 of the video series (8 min long) demonstrates how test coverage information from DFT instrument (e.g. MBIST, OCC) insertion steps at the core level of a design is automatically forwarded to the ATPG step by Tessent for more accurate results. Detailed descriptions … WebMay 29, 2012 · Activity points. 1,105. 1. If my design have PLL or clock divider or clock multiplier as my system clock source. Then I must use OCC flow? or normal flow is OK, too? 2. I had try the normal flow & OCC Flow for my design. But OCC Flow have following Warning : Warning: Clock information for all sequential cells of design is missing. WebMar 22, 2024 · The hierarchical DFT idea of divide-and-conquer for DFT insertion and test generation is extremely valuable for large designs. Once a design is greater than 50 million logic gates, it becomes unnecessarily inefficient to create patterns on the full flat design late in the design flow. With hierarchical DFT, the pattern generation is performed ... chitchat wireless charges
