摘要: A system manipulates stimulus/response signal data associated with an integrated circuit design, such as from a computer-aided engineering simulator, and converts the data into a format acceptable by a tester device which tests a prototype or production integrated circuit. The data is graphically displayed as a waveform and as a vector sequence. On-screen editing of either display is reflected in the other display. Further, the same displays are used to convert the data from event-based data into cycle-based template data compatible with a tester. A mix between event and state data during the conversion is allowed. A standard frame generation language is presented for defining tester frames for each signal within a template or timeset. A workbench editor provides for icon-based control of the system.
摘要翻译: 系统操纵诸如来自计算机辅助工程模拟器的集成电路设计相关联的激励/响应信号数据,并将数据转换成测试原型或生产集成电路的测试仪器可接受的格式。 数据以图形方式显示为波形和矢量序列。 任何显示屏的屏幕编辑都反映在其他显示屏上。 此外,使用相同的显示器将来自事件的数据的数据转换为与测试器兼容的基于循环的模板数据。 允许转换期间事件和状态数据之间的混合。 提供了标准帧生成语言,用于定义模板或时间间隔内每个信号的测试帧。 工作台编辑器提供了基于图标的系统控制。
