Abstract: A processor receives, as input, a first hardware description language (HDL) file defining an entity of a modular circuit design. The first HDL file instantiates, by a storage element declaration in a hardware description language, a storage element within the entity. The first HDL file omits a port map for the storage element. Based on the first HDL file, the processor automatically fully elaborates a port map for the storage element. The processor stores, in data storage, a derived second HDL file defining the entity and including the port map.

Abstract: A first plurality of hardware description language (HDL) files defines a first scope of design forming only a subset of a larger hierarchical integrated circuit design. Technology-specific structures specific to a physical implementation are incorporated in the first scope of design. A second plurality of HDL files defining a first design entity that is at the first scope of design and that includes the technology-specific structures is generated. A third plurality of HDL files defining a second scope of design for the hierarchical integrated circuit design that is larger than and includes the first scope of design is formed. The third plurality of HDL files is processed to form a representation of the second scope of design. Processing the third plurality of HDL files includes replacing a second design entity in the second scope of design lacking at least some technology-specific structures with the first design entity.

Abstract: Based on a directive in a control file, a processor pre-routes, within a hierarchical integrated circuit design, a signal through one or more levels of design hierarchy between a signal source at a higher level of the design hierarchy and an entity instance at a lower level of the design hierarchy. The processor processes entity instances in the design hierarchy in a bottom-up manner to insert technology-specific structures into the hierarchical integrated circuit design. During the processing, the processor inserts into a particular entity instance of the design hierarchy a technology-specific structure and connects the technology-specific structure to the signal pre-routed to the particular entity instance by the pre-routing.

Abstract: A processor receives an expression of design refinement intent with regard to an entity forming a part of a modular circuit design. The entity is defined by a hardware description language (HDL) file, and the expression of design refinement intent identifies an intent region within an implementation of the entity and specifies replacement logic for the region. Based on the expression of design refinement intent, the processor automatically modifies the HDL file by replacing logic within the intent region with the replacement logic. The processor then performs logical synthesis to generate a gate list representation of the modular circuit design as modified.

Abstract: A first plurality of hardware description language (HDL) files describe a hierarchical integrated circuit design utilizing a simplified HDL syntax that omits specification of logical clock connections for at least some entities in the hierarchical integrated circuit design. The hierarchical integrated circuit design as described by the first plurality of HDL files is processed to automatically add logical clock connections for entities in the hierarchical integrated circuit design for which specification of logical clock connections are omitted in the first plurality of HDL files. Based on the processing, a second plurality of HDL files defining the hierarchical integrated circuit design is generated.

Abstract: A face mask covering the face of a user has intended purpose of protecting the user's respiratory system. The face mask has ergonomic shaping for a comfortable fit and secure placement. The complete perimeter of the face mask has an adhesive elastic tape that is ergonomically shaped to hold properties and conform to the facial structure of the user. Removal tabs are connected to points of the elastic tape opposing the face mask contact side. The adhesive elastic tape is bordering the face mask on the area of the face mask, where there is contact to the user's facial skin. The shaping of the adhesive elastic tape conforms with the face mask's configuration, providing sufficient material overlap for bonding. Furthermore, the shape of the adhesive elastic tape has a thickness to maintain a tight grip and secure placement on the user's face with ergonomic fit attributes of facial structure.

Abstract: Systems and methods for encoding a data signal as a pulse position modulation (PPM) signal and decoding a PPM signal to output the original data signal. The method of encoding may comprise receiving an input data signal; converting the data within the input data signal to a sequence of PPM symbol values; and generating a PPM signal comprising an alternating sequence of synchronisation pulses and data pulses. The PPM signal may be generated by generating a plurality of synchronisation pulses at a fixed pulse repetition rate; and generating a sequence of data pulses with each data pulse having a time delay from a preceding synchronisation pulse, whereby the sequence of data pulses represent the sequence of PPM symbol values.
