    • Illustrative embodiments provide a computer-implemented method for resolving indeterminate states by inserting logic into a design. The computer-implemented method receives an original design input from a requester to form a received input and determines whether the received input contains an indeterminate output. Responsive to a determination that the received input contains an indeterminate output, the computer-implemented method generates a temporary design from the received input, wherein the temporary design contains “unique” output and all inputs, updates the temporary design, and synthesizes the original design and each temporary design individually to form a synthesized original design and a set of synthesized temporary designs. The computer-implemented method merges the synthesized original design with the set of synthesized temporary design to form a final design; and returns the final design to the requester.
    • 说明性实施例提供了一种用于通过将逻辑插入到设计中来解决不确定状态的计算机实现的方法。 计算机实现的方法从请求者接收原始设计输入以形成接收到的输入,并确定接收的输入是否包含不确定的输出。 响应于确定接收到的输入包含不确定的输出,计算机实现的方法从接收到的输入生成临时设计,其中临时设计包含“唯一”输出和所有输入,更新临时设计,并且合成原始设计 和每个临时设计单独形成合成的原始设计和一组合成的临时设计。 计算机实现的方法将合成原始设计与合成临时设计集合合并形成最终设计; 并将最终设计返回给请求者。

    • The invention is generally directed to a method and apparatus for validating a specified manufacturing test rule, which pertains to an electronic component. One embodiment comprising a method includes the step of generating a file of test data sets, wherein each test data set in the file is valid for the rule. Each test data set includes a stimulus comprising one or more single input vectors, and further includes a set of results that are expected, when the stimulus is applied to the electronic component. The method further comprises constructing a testbench to prepare each of a plurality of testcases for simulation, wherein each testcase corresponds to the stimulus and the expected output results of one of the test data sets, and each testcase is disposed to be simulated separately, or independently, from every other testcase. The method further comprises selectively preparing each of the testcases for simulation, in order to provide simulated results for the stimulus corresponding to each testcase. The expected results and the simulated results are compared for each testcase, in order to determine whether there are any differences therebetween. Each of the above steps can be carried out using means that are completely automated. Thus, the entire method for validating manufacturing test rules can likewise be completely automated. Also, the processing applied to different test cases can occur simultaneously or in parallel, to substantially reduce the processing burden.
    • 本发明一般涉及用于验证与电子部件有关的特定制造测试规则的方法和装置。 包括方法的一个实施例包括生成测试数据集的文件的步骤,其中文件中设置的每个测试数据对于该规则是有效的。 每个测试数据集包括包括一个或多个单个输入向量的刺激,并且还包括当将刺激应用于电子部件时预期的一组结果。 该方法还包括构建测试台以准备用于模拟的多个测试箱中的每一个,其中每个测试用例对应于一个测试数据组的刺激和预期输出结果,并且每个测试用例被设置为单独模拟或独立地模拟 ,从每个其他测试用例。 该方法还包括选择性地准备每个用于模拟的测试箱,以便提供对应于每个测试箱的刺激的模拟结果。 对每个测试用例比较预期结果和模拟结果,以确定它们之间是否存在差异。 可以使用完全自动化的装置来执行上述步骤中的每一个。 因此,用于验证制造测试规则的整个方法同样可以完全自动化。 此外,应用于不同测试用例的处理可以同时或并行地发生,从而大大减少处理负担。

    • A system for creating manufacturing test rules. Stimuli for an electronic design are generated automatically by a stimuli generator. The stimuli generator takes into account certain limitations of the design when automatically generating the manufacturing test rules. The design is tested by a testbench using the stimuli. A simulation log for the design is generated by the testbench. The simulation log is then processed by a simulation log processor. An HDL representation of the design is generated by the simulation log processor using the processed simulation log. A gate-level version of the design is generated by a synthesis tool using the HDL representation of the design. The gate-level version of the design is further processed by the synthesis tool to make any necessary modifications. Then, the gate-level version of the design is outputted as the final manufacturing test rule. Thus, creating manufacturing test rules can be completely automated.
    • 用于创建制造测试规则的系统。 电子设计的刺激是由刺激发生器自动产生的。 当自动生成制造测试规则时,刺激发生器考虑到设计的某些限制。 该设计由使用刺激的测试台进行测试。 该设计的仿真日志由测试平台生成。 仿真日志由仿真日志处理器处理。 设计的HDL表示由仿真日志处理器使用处理的仿真日志生成。 设计的门级版本由使用设计的HDL表示的综合工具生成。 设计的门级版本由综合工具进一步处理,以进行任何必要的修改。 然后,设计的门级版本作为最终制造测试规则输出。 因此,创建制造测试规则可以完全自动化。
