摘要： A block diagram editor system and method is implemented in a computer workstation that includes a CRT and a mouse, graphics and windowing software, and an external communications interface for test instruments. The computer is programmed for constructing, interconnecting and displaying block diagrams of functional elements on the CRT. From prestored routines for each functional element, the software assembles and executes a program that emulates the functional operations of each element and transfers data from output from each element in turn to an input of a succeeding block, as determined by the block diagram configuration. The block functions include signal generating and analysis functions, and functions for control of various types of test instruments, which can be interactively controlled through the CRT and mouse. The computer converts desired outputs of the instruments into control settings and receives, analyzes and displays data from the instruments. Blocks can also be grouped into macroblocks.

摘要： A block diagram editor system and method is implemented in a computer workstation that includes a Cathode Ray Tube (CRT) and a mouse, graphics and windowing software, and an external communications interface for test instruments. The computer is programmed for constructing, interconnecting and displaying block diagrams of functional elements on the CRT. From prestored routines for each functional element, the software assembles and executes a program that emulates the functional operations of each element and transfers data from output from each element in turn to an input of a succeeding block, as determined by the block diagram configuration. The block functions include signal generating and analysis functions, and functions for control of various types of test instruments, which can be interactively controlled through the CRT and mouse. The computer converts desired outputs of the instruments into control settings and receives, analyzes and displays data from the instruments. Blocks can also be grouped into macroblocks.

摘要： Computer-controlled test and measurement systems, including resources having multiple states and resources having multiple inputs, are modeled as data flow diagrams of topologically interconnected resources. A set of "tasks" are defined for changing the states of multiple-state resources and causing software resources to produce output data. Methods and apparatus, including internal and external task ordering rules, are provided to automatically interleave such tasks and implement input-ordering restrictions. Thereby, a sequence of tasks is produced to control the systems so as to assure valid data collection and protect physical resources from abuse. Data structures are illustrated for implementing the invention in an object-oriented programming environment.

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.
