Concurrent timed digital system design method and environment

The present invention relates to the design of an essentially digital system. As one example of digital systems, these may perform real-time transformations on time discrete digitized samples of analogue quantities. An example of such a system is a digital communication system. The transformations on the data can be specified in a programming language and executed on a processor such as a programmable processor or directly on application specific hardware. In accordance with the present invention the digital system is described as a set of threads in a description language. Alternative names for a thread are tasks and processes. The set of threads defines a representation or model of the digital system. In accordance with the present invention, the representation or model is preferably executable at each stage of the design independent of the current level of abstraction of that representation or model. With description language is meant a programming language. In accordance with the present invention each of the threads has a variable having an assignable value which represents the “local time” of said thread, i.e. a time associated only with that thread, which can be used for sequencing the processing of that thread with respect to other threads. With the word “local” is meant that the time is an attribute of the thread only. In accordance with the present invention a means is provided for the designer to assign a delay to each thread or operation within a thread, this delay representing for instance the processing time for the respective operation or thread on a processing engine, e.g. a computer. By this means, not only can the processing of threads be scheduled but also the designer may assign a value representative of an elapsed time for the processing of a thread or operation on a processing engine. In addition, the threads may be refined concurrently, while still keeping their local time so that after the refining process the new representation of the digital system is executable, i.e. the processing of the refined threads can be scheduled without divergence from the specification.

Method and apparatus for functional language temporal extensions, dynamic modeling, and verification in a system-level simulation environment

A method and apparatus for functional simulation of a system 104 in a system-level simulation and verification environment using a functional language 100 derived from a selected Scheme Language standard, and a simulator 105 for simulating verification functions 101 and model functions 102 expressed in the functional language 100. The functional language 100 has syntax extensions expressed as dynamic “always @” and “@” blocks, and all other event expressions which are similar to Verilog and other RTL (Register-Transfer Level) HDL (Hardware Description Language) temporal syntax constructs. A composer 103 is further used to connect verification functions 101 with model functions 102. Model functions 102, represented as mutable state functional objects along with selected test, monitor, checker and user-defined functions, sample reactive responses and ensure concurrent drive of abstracted signals for the simulator 105. The simulator 105 can function as a formal verifier to formally verify the model functions 102, or a synthesizer to transform programs written in a restricted subset of the functional language 100 into an internal control and data flow format or any synthesis-ready language. A system-level modeling and simulation environment enhanced with a graphical user interface facilitates the usage of the functional language 100.

Method and system for realizing automatic verification of form and communication among multiple systems

This invention provides a method for realizing automatic verification of a form and communication among multiple systems. The method comprises the following steps: a server side create an html form, and the server side re-draws the form to a display container; a user side clicks a form element, and sends a triggering event for clicking the form element to the server side; according to the triggering event for clicking the form element, the server side realizes multi-field automatic combined verification of the drawn form through a built-in verification process engine, and sets data calling and binds data in the display container; the server side puts the verified form into the display container; and when the user side clicks the form element, the server side achieves remote procedure calling and cross-domain calling of field data through a built-in network service. By adopting the method provided by the invention, the higher degree of abstraction of the form is achieved through the multi-field automatic combined verification, and multiple platforms can be automatically switched; the form is filled automatically according to the associated fields; and thus, the development difficulty is effectively reduced.

Method for operating and monitoring a control device, corresponding operating/monitoring device, control device and machine with such a control device, and uses of the method together with data storage media

There is described a method, wherein an interpreter program is executed on a control device and is adapted to access scripts having display components and program architectures. Said program architectures are enabled to access operating data of the firmware of the control device, said operational data being convertible to display data of a defined display format and vice versa. The scripts are run, the program architectures compiling the corresponding result in the form of display components with optionally the display data in the defined display format and making the result available to the operating/monitoring device. A display program is executed on the reporting/monitoring device in order to display at least the display components in the defined display format. References to at least one script on the control device are deposited in the display components. These references are connected to an event, and the interpreter program initiates and runs the corresponding script when this event occurs. The operating/monitoring device can no longer directly access the sensitive firmware of the control device. Communication is carried out via an interpreter program. Access to the actual control application is no longer possible.
