摘要： A method and system for providing centralized access to count event information from testing of a hardware simulation model within a batch simulation farm which includes simulation clients and an instrumentation server. Count event data for said hardware simulation model is received by the instrumentation server from one or more simulation clients. A first and a second counter report are generated for the hardware simulation model, in which the first and second counter reports are derived from the count event data received by the instrumentation server. The first counter report is compared to the second counter report, and responsive to this comparison, a counter difference report is generated within the instrumentation server that conveys count event trends associated with the simulation model under different simulation testcases.

摘要： According to one method of simulation processing, a count event counter for a count event is created within instrumentation of a hardware description language (HDL) simulation model of a design and a threshold greater than 1 is established for the count event counter. The design is then simulated utilizing the HDL simulation model, and occurrences of the count event are accumulated in the count event counter to obtain a count event value. Thereafter, an indication of whether the count event value of the count event exceeds the threshold is recorded within a data storage subsystem.

摘要： A method and system for minimizing redundancy in collected harvest event testcases from a batch simulation farm which includes a harvest testcase server that collects simulation data for a simulation model from at least one simulation client. In accordance with the method of the present invention, a testcase is executed on the simulation model within a simulation client. Responsive to the testcase triggering a harvest event, the harvest event is compared with a list of harvest events that have previously been triggered within the simulation model. In response to determining that the harvest event has not been previously triggered within the simulation model, the testcase is delivered to the harvest testcase server.

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： 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： According to one method of simulation processing, instrumentation code, such as an runtime executive (rtx), receives one or more statements describing an count event and identifying the count event as an outlying count event. While simulating a design utilizing the HDL simulation model, occurrences of the outlying count event are counted to obtain a count event value. Simulation result data obtained from simulating the design is then received and processed. In the processing, the count event value is recorded within a data storage subsystem responsive to a determination of whether or not the count event value of the outlying count event exceeds a previously recorded count event value.

摘要： Disclosed herein is a method of storing data results of simulation processing of a hardware description language (HDL) model based upon keywords. In accordance with the method, result data obtained by simulation of at least one HDL model are received. In association with the result data, a plurality of value sets is received, where each value set includes at least one keyword having an associated value. Each keyword identifies a parameter external to the HDL model that affected the result data. The data results are stored within a data storage subsystem in association with the plurality of value sets such that particular result data are attributable to particular ones of the plurality of value sets. In one embodiment, a keyword table is built in the data storage system that indicates which data subdirectories store result data associated with particular value sets. The result data can then be queried based upon selected keywords of interest, for example, by reference to the keyword table.
