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： A method and system are disclosed that utilize the expressiveness of hardware description languages for automatically adjusting counting rates of instrumentation within a simulation model of a digital circuit design, during simulation of said digital circuit design. According to the present invention a design entity that will be incorporated into a simulation model of a digital circuit design is described utilizing a hardware description language. The design entity operates, during simulation, in conformity with a design cycle that consists of a multiple of a simulator cycle. Next, an instrumentation entity is described utilizing the same hardware description language. The description of the instrumentation entity contains logic to detect occurrences of a count event that occurs in conformity with the design cycle during simulation. Thereafter, an instrumentation logic block associated with the instrumentation entity is automatically generated and utilized for counting occurrences of the count event detected by the instrumentation entity. Finally, the design cycle is encoded within the instrumentation entity, such that the output logic block is automatically adjusted to count in conformity with the design cycle.

摘要： Disclosed herein is a method of managing data results of simulation processing of a hardware description language (HDL) model based upon keywords. In accordance with the method, a restriction list associated with the HDL model is received. The HDL model has a maximum number of possible keyword/value pairs sets for which result data can be obtained, and the restriction list specifies a fewer number of keyword/value pair sets for which the result data can be queried based upon at least one keyword. In response to receipt of result data obtained by simulation of the HDL model, the result data are stored within a data storage subsystem by reference to the restriction list, such that particular result data attributable to each of the plurality of keyword/value sets is separately accessible.

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： A method for determining the configuration of a digital design first obtains a set of latch values of a plurality of latches within the digital design. A setting of a Dial instance is then determined based upon the set of latch values by reference to a configuration database that specifies a mapping table uniquely associating each a plurality of different settings of the Dial with a respective one of a plurality of different sets of latch values. The setting of the Dial instance is then output. In one embodiment, the setting of the Dial is contained in a simulation setup file utilized to configure a simulation model to a state approximating the state of the digital design represented by the set of latch values.

According to one method, a configuration database including at least one data structure representing an instance of a Dial entity is received. The instance of the Dial entity has at least an input, an output, and at least one associated latch within a digital design. A value of the output of the instance of the Dial entity controls a value stored within the associated latch. A control file is also received. The control file indicates that at least one associated latch data structure is to be inserted within the configuration database to represent the latch during multi-cycle simulation. In response to receipt of the configuration database and the control file, the configuration database is processed with reference to the control file to insert within the configuration database at least one latch data structure and to associate, within the configuration database, the at least one latch data structure with the instance of the Dial entity.

摘要： A simulation control program receives a hardware description language (HDL) model including design entities and count event registers. Each count event registers is associated with a respective instance of an event. The count event registers include first and second registers for counting occurrences of a same replicated event generated within different instances of a same design entity having a same hierarchical level within the HDL model. The simulation control program also receives a correlation data structure indicating which count event registers are associated with instances of the same replicated event. During simulation processing, each of the count event registers maintains a respective count value representing a number of times an associated event instance occurs. The simulation control program sums count values of the first and second count event registers in accordance with the correlation data structure and outputs a count event data packet containing the aggregate count value.

摘要： A system configuration database is constructed in volatile memory by first determining which types of integrated circuits are present in a hardware system and the number of each type. In response to a determination, a system configuration database is loaded into volatile memory that includes a respective chip hardware database for each type of integrated circuit in the hardware system. Each chip hardware database defines a Dial entity controlling which of a plurality of different possible latch values is placed in a hardware latch of the associated type of integrated circuit. The system configuration database includes at least a first chip hardware database for a first type of integrated circuit that contains per-instance information for each of the multiple instances of the first type of integrated circuit within the hardware system.
