  • Patent number: 9336123
    Abstract: A system and method are provided for establishing an automated debugging environment in an Electronic Design Automation (EDA) work flow. A user interface is provided for interfacing with a user by displaying a list of debuggable parameters, accepting a selection thereof from a user, and automatically locating both the callback function which sets the selected parameter, and the source code file which contains the callback function. Additionally, it is determined whether the callback function sets solely the selected parameter, or several different parameters, and an automatic breakpoint is set accordingly to break only responsive to the selected parameter. On execution of the modified callback function, execution will be arrested by the automatically-set intelligent breakpoint and a debugging user interface will be generated and provided to the user with a display of the relevant source code, callback function, parameter names and values, system state, and the like.

  • Patent number: 8719745
    Abstract: A system and method are provided for establishing an automated debugging environment in an Electronic Design Automation (EDA) work flow for the debugging of parameterized cells (PCELLS/PyCELLS) in a layout. A user may merely select a particular PCELL within a hierarchical PCELL and the system and method will determine dependencies thereof. The source code for the selected PCELL and its dependencies may be located and loaded. At least one breakpoint may be set in the source code of the selected PCELL. The source code for the selected PCELL and its dependencies may be executed to be arrested at the set breakpoints.

  • Patent number: 5882740
    Abstract: A method is provided for efficiently producing an entirely quality-controlled CVD diamond. A CVD process is interrupted at an early stage and the deposit is taken out of the reaction chamber, before a significant mass is accumulated, and is inspected by means of cathodoluminescence. The spectrum are compared with a given reference in terms of peak position, half width and 20%-value width in coordination. The observed deviation allows to determine whether to maintain or alter the settings.A diamond substance of acceptable quality which is properly specified in terms of the CL parameters is also provided.
