Abstract: An access control system controls access to a shared resource for various functional circuits. The access control system can include a comparison circuit, a processing circuit, and a selection circuit. The comparison circuit receives identification data associated with a functional circuit based on a transaction initiated by the functional circuit, and compares the identification data and reference data to generate a select signal. The processing circuit receives error data and response data outputted by the shared resource based on an execution of the transaction, and generates another response data. The selection circuit selects and outputs, based on the select signal, one of the response data outputted by the shared resource and the response data generated by the processing circuit as a transaction response that is to be provided to the functional circuit.

Abstract: A gimbal assembly is provided that allows for more than a single rotation about a rotational axis in both a first rotational direction and a second rotational direction.

Abstract: An EDA tool for verifying timing constraints of an integrated circuit (IC) design includes a processor and a memory that stores register transfer level (RTL) code of the IC design and a timing constraint file. The processor generates a netlist based on the RTL code, and identifies asynchronous clock paths, false paths and multi-cycle paths in the netlist using the timing constraint file. The processor then inserts buffer cells for logic cells in the netlist. The processor also inserts buffer cells in the asynchronous clock paths, false paths, and multi-cycle paths. The processor delay annotates logic cells and clock delay cells with a zero delay value and the buffer cells with known delay values. The processor generates a modeled standard delay format (SDF) file and performs a gate level simulation (GLS) using the modeled SDF file.
