摘要： A method and system for associating instrumentation data with a simulation model within a batch simulation farm in which a simulation client communicates with an instrumentation server to process simulation data with respect to the simulation model. In accordance with the method of the present invention, an instrumentation eventlist is delivered from the simulation client to the instrumentation server. The eventlist contains instrumentation event information for the simulation model. Next, within the instrumentation server, a digital signature is computed that uniquely identifies contents of the instrumentation eventlist as being associated with the simulation model. Responsive to receiving simulation data from the simulation client, the digital signature is utilized to associate the simulation data with the simulation model.

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： A method and system for resolving testcase collection inconsistencies between a testcase list which includes testcases that have triggered harvest events within a simulation model, and a harvest hit table which records harvest events that have been triggered during simulation of the simulation model. First, the harvest hit table is updated from a simulation client to include a harvest event triggered by a testcase during simulation of the simulation model. The testcase is then collected within the testcase list. Finally, testcases identified within the testcase list are compared to testcases identified within the harvest hit table to determine inconsistencies therebetween.

摘要： A system and computer program product 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： A method and system for disabling an instrumentation event in a simulation model within a batch simulation farm in which a simulation client communicates with an instrumentation server to process simulation data with respect to the simulation model. An instrumentation event disable list is assembled within the instrumentation server. The assembly of the event disable list includes identifying an instrumentation event to be disabled during simulation processing of the simulation model, and delivering to the instrumentation server an instrumentation event name corresponding to the instrumentation event to be disabled. Prior to simulating the simulation model within the simulation client, the instrumentation event disable list is retrieved from the instrumentation server, and instrumentation events are disabled as specified within the instrumentation event disable list.

摘要： An integrated-circuit design is provided which is represented by a hierarchial data structure. In accordance with the method and system of the present invention, an integrated-circuit design which includes at least one parent circuit represented by a set of parent circuit level data and at least one child circuit represented by a set of child circuit level data. For an open circuit connection within the child circuit, a determination is made as to whether or not the open circuit connection is permissible. In response to a determination that the open circuit connection is permissible, another determination is made as to whether or not the number of I/O pins within the child circuit is greater than the number of open circuit connections within the child circuit. In response to a determination that the number of I/O pins within the child circuit is greater than the number of open circuit connections within the child circuit, the set of child circuit level data is integrated into the set of parent circuit level data. Finally, a determination is made as to whether or not the open circuit connection is closed within the integrated set of parent circuit level data. An error message will be displayed if the open circuit connection is not closed within the integrated set of parent circuit level data.
