WebI would suggest you to go through the topics in the sequence shown below –. DFT, Scan & ATPG. What is DFT. Fault models. Basics of Scan. How test clock is controlled for Scan Operation using On-chip Clock Controller. Why do we need OCC. How test clock is controlled by OCC. Example of a simple OCC with its systemverilog code. WebWhen using power gates on the low V th cells the output must be isolated if the next stage is a high V th cell. Otherwise it can cause the neighboring high V th cell to have leakage when output goes to an unknown state due to power gating. Gate control slew rate constraint is achieved by having a buffer distribution tree for the control signals.

Insertion of power switch cells is a necessity for on-chip power shut-off. Power switch cells can be inserted in a column or a ring fashion. EDA tools may be able to automatically insert the power switch cells for the designer or they can manually insert these constructs. Power switches are also inserted during the floorplanning or ...

These isolations can be implemented either as a part of the retention flop or we can have a separate isolation cell connected to the CK/RST pin. The advantage with the first implementation is that it reduces the ...

Examples of CDC Issues: 1) Data Loss in Fast to Slow Xfer. 2) Improper Data Enable Sequence. 3) Re-Convergence of Synced Signals. 4) Reset Synchronization.
WebThe strongly fail-safe property is achieved by means of concurrent checking techniques. The interest of these interfaces is that they can be implemented in VLSI, while the conventional fail-safe interfaces require using discrete components. A formal theory of fail-safe systems is developed to guide the implementation of the new solutions.
