摘要： A method for programming an FPGA, wherein a library, which includes elementary operations and a particular latency table for each of the elementary operations of the library is provided. Each latency table indicates the latency of the particular operation for a plurality of clock rates of the FPGA and for a plurality of input bit widths of the particular operation during the execution on the FPGA, depending on the input bit width of the particular operation and the clock rate of the FPGA. A data path indicating a consecutive execution of at least two elementary operations of the library on the FPGA is defined. The latencies given for the particular input bit width of the particular elementary operations of the data path for a plurality of different clock rates in the latency tables are detected and added, then one of the clock rates is selected.

摘要： A computer project management system and method for the creation of an electronic control unit software is provided. The system has a software architecture tool configured to design a graphical model of an electronic control unit for a motor vehicle. A behavior model tool converts the graphical model into a computer readable production code. A software container has a file generated based on the electronic control unit. A container manager compares the software container with a prior software container during the importation or exportation of the software container to or from the software architecture tool or the behavior model tool, and a comparison list is generated indicating whether interface modifications for the electronic control unit were made. The comparison list is then displayed to a user on a display screen.
