Abstract: Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction.

Abstract: Systems and methods for predicting interactions between objects and predicting a trajectory of an object are presented herein. A system can obtain object data associated with a first object and a second object. The object data can have position data and velocity data for the first object and the second object. Additionally, the system can process the obtained object data to generate a hybrid graph using a graph generator. The hybrid graph can have a first node indicative of the first object and a second node indicative of the second object. Moreover, the system can process, using an interaction prediction model, the generated hybrid graph to predict an interaction type between the first node and the second node. Furthermore, the system can process, using a graph neural network model, the predicted interaction type between the first node and the second node to predict a trajectory of the first object.

Abstract: The present invention discloses a DFT (Design for test) methodology to integrate synchronous double-clock latches to synchronize data transferring between two asynchronous clock domains, where the conventional lockup-latches (asynchronous latches) are automatically inserted to connect/combine the two independent asynchronous DFT chains for a more compacted solution. If the asynchronous latches are replaced by the synchronous double-clock ones, the static timing analysis (STA) will check both ends of the latches, therefore, the full combined chain is safe from the setup-hold issues. This method utilizes the automatic flow of asynchronous latches insertion to connect independent DFT chains. Then these conventional latches are replaced by synchronous ones. Both the synthesis, the physical implementation flows in the DFT design and the automatic-test pattern generation (ATPG) scheme have been modified to match these replacements.

Abstract: Described is a design to synchronize and prevent any clock timing issues associated with two clock domain crossing (CDC) in Design for Testing (DFT) and other CDC applications. In order to avoid any meta-stability issues associated with the sensitive edges of the two clock domains, the synchronization scheme splits the incoming data of the first clock domain into three branches, from which a finite state machine is to choose the correct branch for data transfer to the second clock domain. The selected branch will be the ‘safe’ one that guarantees there will be no timing issue at the second clock domain. This methodology can be applied in IC design that needs to optimize area and performance.
