摘要： Within a display device, a respective one of a plurality of design graphical representations is displayed for each of a plurality of hierarchically arranged design entity instances within a simulated system. The design entity instances include a particular design entity instance containing a latch that is represented by a particular design graphical representation. A configuration entity instance associated with the particular design entity is identified within a configuration database associated with the simulated system. The configuration entity instance has a plurality of different settings that each reflects a value of the latch. Within the display device, a configuration graphical representation of the configuration entity instance is presented in association with the particular design graphical representation corresponding to the particular design entity instance. In addition, a current setting of the configuration entity instance is presented concurrently with the configuration graphical representation.

摘要： A method is disclosed of associating a mapping function with a configuration construct of a digital design defined by one or more hardware description language (HDL) files. According to the method, in the HDL files, a configuration latch is specified within a design entity forming at least a portion of the digital design. In addition, a Dial is specified that defines a relationship between each of a plurality of input values and a respective one of a plurality of different output values. The HDL files also include a statement that instantiates an instance of the Dial in association with the configuration latch such that a one-to-one correspondence exists between a value contained within the configuration latch and an input value of the instance of the Dial. The HDL files further include a statement associating the Dial with a mapping function that applies a selected transformation to values read from or written to the instance of the Dial.

摘要： According to a one method of simulation processing, a file is utilized to describing a hardware description language (HDL) simulation model of a design. The file includes one or more statements describing a count event and identifying the count event as an outlying count event. From the file, a count event counter for the outlying count event is created within HDL instrumentation of the simulation model. The design is then simulated utilizing the HDL simulation model, and occurrences of the outlying count event are counted within the count event counter to obtain a count event value. In response to receiving the count event value of the outlying count event, the count event value is recorded within a data storage subsystem based on whether the count event value of the outlying count event exceeds a previously recorded count event value.

摘要： In a method of data processing, a database defines a Dial entity and at least one instance of the Dial entity. Each instance of the Dial entity has an input having a plurality of different possible input values and one or more outputs, and each of the plurality of different possible input values has a different associated output value set for the one or more outputs. Each instance of the Dial entity determines a value of at least one of a plurality of configuration latches in a digital system separate from the database. The database also associates with the Dial entity at least one set of biasing weights that, when applied, determines a probability of each instance of the Dial entity having particular ones of the plurality of different possible input values. In response to a call to set the plurality of configuration latches, the database is accessed to apply the at least one set of biasing weights to select one of the plurality of different possible input values for the at least one instance of the Dial entity. The plurality of configuration latches in the digital system are set based upon the output value set for the one or more outputs of the at least one instance of the Dial entity.

摘要： 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.

摘要： 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.

摘要： 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. In response to locating the definition of the configuration construct, the model build tool automatically creates an instrumentation entity within the design data. The instrumentation entity has one or more inputs logically coupled to the one or more configuration latches and one or more outputs for providing signals indicating characteristics of the configuration construct during simulation.
