  • Patent number: 10585650
    Abstract: A computer-implemented method for generating program code based on one or more blocks of a block diagram in a technical computing environment including a model editor and a code generator. The method comprises opening the block diagram in the model editor, the block diagram comprising a delay block that delays a signal received by an input port for a number of periods before being emitted at an output port, determining that a composite signal is connected to the input port, and generating definitions for variables, the variables including a state buffer, a pointer and an index. The method further comprises generating loop code, the loop code comprising instructions for setting the pointer to a position in the state buffer with an offset of index, instructions for outputting elements from the state buffer, instructions for inputting the composite signal to the state buffer, and instructions for adjusting the index.

  • Patent number: 10503485
    Abstract: A method for generating program code based on one or more blocks of a block diagram in a technical computing environment, an identifier being assigned to at least one, preferably each, of the one or more blocks of the block diagram. A processor opens the block diagram in the model editor, converts the block diagram to an intermediate representation using the code generator, wherein the conversion comprises checking if a replacement condition is fulfilled for a current block in the block diagram. Checking the replacement condition includes verifying that a predefined functional code unit is assigned to the identifier of the current block, in that case changing the block to a placeholder containing input/output-definitions but no functionality. The processor then converts the intermediate representation to program code, the conversion comprising adding a predefined functional code unit from the data definition tool to the definition code corresponding to the placeholder block.

  • Patent number: 10481931
    Abstract: According to the invention, the operating software 10 of a technical system, particularly of a controller for controlling or regulating at least one technical device, is modified by virtue of hardware-dependent software components in the operating software 10 executable directly on the technical system not being executed and instead the functional behavior of the hardware-dependent software components being recreated by substitute functions 23. To this end, the hardware-dependent software components are automatically identified (step S1), and the substitute functions 23 are automatically ascertained or produced. On execution in a suitable simulation environment 200 (step S3), the operating software 20 modified in this way simulates the technical system independently of the real hardware 100 thereof.

  • Patent number: 10394989
    Abstract: A method for creating an FPGA netlist generated from an FPGA source code and at least one shadow register. The FPGA source code defines at least one function and at least one signal. The shadow register is assigned to the at least one signal, and is arranged and provided to store the value of the assigned signal at runtime. An option for reading out the stored signal value at runtime is provided. The function defined in the FPGA source code is not changed by the shadow register. The function described by the FPGA source code is executed by the FPGA, and a functional decoupling of the shadow register from the function described in the FPGA source code is provided. Via the decoupling, the shadow register maintains the signal value stored at the time of the decoupling while the function described in the FPGA source code is being executed.
