Abstract: To program a first programmable gate array, for example a first FPGA, in a distributed computer system, a configuration of a first configuration logic on the first programmable gate array is provided. The first configuration logic is configured to receive a first user bitstream from a configuration software for configuring a first user logic on the first programmable gate array and to store the first user bitstream on a non-volatile memory of the first programmable gate array for the purpose of subsequently configuring a first user logic on the first programmable gate array according to the specifications from the first user bitstream. In an expansion stage of the invention, a configuration of a programming logic on the first programmable gate array is also provided for programming a second programmable gate array, which is connected to the first programmable gate array to form a daisy chain.

Abstract: A method for accessing signals of a programmable logic device having a functional level and a configuration level at run time when the programmable logic device is executing a predefined configuration. An access to at least one signal value that has a number of bits is requested. The individual bits in the configuration are each located in an address unit with one address offset apiece such that one or more bits of a signal value are located in one address unit. A bitwise access to the requested signal values takes place, wherein the accesses to the individual bits are sorted as a function of the address unit containing the applicable bit in such a manner that the accesses to all bits located in an address unit take place in sequence as a function of the address offset, independently of the signal containing the applicable bit.

Abstract: A method for planning the design of partitions for a programmable gate array comprising different types of logic blocks of predetermined position, and a plurality of program routines comprising at least one first program routine and at least one further program routine. A mapping of a first partition of the programmable gate array with the first program routine and at least one further partition of the programmable gate array with the at least one further program routine is performed. The need of the first program routine for the individual types of logic blocks is determined. Meeting this need with the logic block resources of corresponding type available in the first partition. At least one logic block of corresponding type from the further partition or at least one of the further partitions into the first partition is transferred.

Abstract: A computer-implemented method for restructuring a predefined distributed real-time simulation network, wherein the simulation network has a plurality of network nodes and a plurality of data connections, wherein each network node has at least one data connection interface for connecting a data connection, wherein the network nodes are at least partially in communication via the data connections, and wherein during operation of the simulation network a simulation application is executed on at least one network node. The method permits a structure for the real-time simulation network to be automatically found in which the critical communication connections are reduced and avoided as much as possible by determining the topology of the simulation network so that topology information concerning the network nodes and the data connections between the network nodes is available by determining expected values for node data rates or node latencies for the network nodes of the simulation network.
