A method, system, and data structure for overriding a signal during model simulation. An override signal port is instantiated within a model for delivering an override signal from an instrumentation entity to a signal selection means, wherein the signal selection means selects between the signal and the override signal. A signal override is declared during model simulation, and in response to the declared signal override, the override signal is selected utilizing the signal selection means.

A method, system, and data structure for processing and managing a simulation event during model simulation. In accordance with the present invention, a design entity identifier is associated with the simulation event within a simulation event declaration statement. The event declaration statement includes a design entity name field containing data representing an entity name of a design entity from which the simulation event is generated. Occurrences of the simulation event are evaluated within said simulation model in accordance with the design entity identifier. An instantiation identifier field may be included within the event declaration to enable hierarchical and non-hierarchical processing of the event.

In a hardware definition language (HDL) file among one or more files, one or more design entities containing a functional portion of a digital system are specified. The one or more design entities logically contain a plurality of latches having a respective plurality of different possible latch values that each corresponds to a different configuration of the functional portion of the digital system. With one or more statements in the one or more files, a multi-level Dial tree is defined that includes a selective control Dial (SCDial) entity at an upper level that is associated with at least one design entity. The SCDial entity has a Dial input, a plurality of Dial outputs coupled to inputs of the plurality of lower level Dials, and a mapping table indicating a mapping between each of a plurality of possible input values of the Dial input and a respective one of a plurality of sets of output values for the plurality of Dial outputs. At least one set of output values in the mapping table specifies output values for fewer than all of the plurality of Dial outputs. Each specified output value reflects a setting of at least one lower level Dial, and settings of the lower level Dials reflect which of the plurality of different possible configuration values is loaded in the plurality of configuration latches.

A method and program product for instrumenting a hardware description language (HDL) design entity. The design entity is created utilizing a HDL source code file within the syntax convention of a platform HDL. In accordance with the method of the present invention an instrumentation entity is described within the HDL source code file utilizing a non-conventional syntax comment such that the instrumentation entity is embedded within the design entity without being incorporated into an overall design in which the design entity is incorporated. In accordance with a second embodiment, the HDL source code file includes a description of at least one operating event within the conventional syntax of the platform HDL, and the method of the present invention further includes associating the instrumentation entity with the operating event utilizing a non-conventional syntax comment within the HDL source code file.

In a method of compiling a simulation model of a digital design, a compiler receives an indication of a desired set of instrumentation entities to be included within a simulation model of a digital design described by a plurality of hierarchically arranged design entities. The instrumentation entities monitor logical operation of one or more of the plurality of design entities during simulation for occurrence of events of interest. In response to the indication, the compiler determines by reference to a bill-of-materials of a previously compiled file whether or not the previously compiled file was compiled with instrumentation entities compatible with the desired set of instrumentation entities. In response to determining that the previously compiled file was compiled with compatible instrumentation entities, the compiler compiles the simulation model of the digital design utilizing the previously compiled file in accordance with the indication.

A method, data processing system, and program product for building an instrumented simulation model of a digital design are disclosed. According to the method, a model build tool locates, within design data collectively defining a simulation model of the digital design, a definition of a configuration construct specifying a relationship between values of one or more configuration latches within the digital design and settings of the configuration construct.

A method of producing an integrated circuit having a vertical MOS transistor includes doping a substrate to form a layer adjacent to its surface and forming a lower doped layer serving as the transistor's first source/drain region. The transistor's channel region is formed by doping a central layer above the lower layer. A second source/drain region is formed by doping an upper layer above the central layer. The upper, central and lower layers form a layer sequence having opposed first and second faces. A connecting structure is formed on the first face to electrically connect the channel region and the substrate. The connecting structure laterally adjoins at least the central layer and the lower layer, and extends into the substrate. A gate dielectric and adjacent gate electrode are formed on the second face.

A method and system that utilize the expressiveness of hardware description languages for efficiently and comprehensively monitoring performance characteristics of a digital circuit design during simulation. According to the present invention, a design entity that is part of a digital circuit design is first described utilizing a hardware description language. Next, a counting instrument is described utilizing the same hardware description language. The counting instrument is designed to detect occurrences of a count event within the design entity during simulation of the digital circuit design. The counting instrument is associated with the design entity utilizing a non-conventional call, such that the counting instrument may be utilized to monitor each instantiation of the design entity within the simulation model without the instrumentation entity becoming incorporated into the digital circuit design. In association with the counting instrument, a linear feedback shift register is automatically generated for recording the number of occurrences of the count event within the design entity.
