Some examples described herein relate to routing in routing elements. In an example, a design system includes a processor and a memory, storing instruction code, coupled to the processor. The processor is configured to execute the instruction code to model a communication network comprising switches interconnected in an array of data processing engines (DPEs), generate global routes of nets in the modeled communication network, generate detailed routes of the nets using the global routes, and translate the detailed routes to a file. Each of the switches has multiple input or output channels connected to another switch that are modeled as a single input or output edge, respectively, connected to the other switch. Each global route is generated through edge(s) of the switches. Each detailed route is generated comprising identifying one of the multiple input or output channels modeled by each edge through which the respective global route is generated.

Data processing engine (DPE) array routing

Some examples described herein relate to global mapping of program nodes of a netlist of an application. In an example, a design system includes a processor and a memory coupled to the processor. The memory stores instruction code. The processor is configured to execute the instruction code to obtain a netlist of an application. The netlist contains program nodes and respective edges between the program nodes. The application is to be implemented on a device comprising an array of data processing engines. The processor is also configured to execute the instruction code to generate a global mapping of the program nodes based on a representation of the array of data processing engines and using an integer linear programming (ILP) algorithm; generate a detailed mapping of the program nodes based on the global mapping; and translate the detailed mapping to a file.

Data processing engine (DPE) array global mapping

An example method for compiling by a processor-based system includes obtaining a netlist of an application, the netlist containing program nodes and respective edges between the program nodes, the application to be implemented on a device comprising an array of data processing engines; generating a global mapping of the program nodes based on a representation of the array of data processing engines; generating a detailed mapping of the program nodes based on the global mapping, the detailed mapping assigning input/outputs of programmable logic (PLIOs) of the device to channels in an interface of the array of data processing engines, the detailed mapping further assigning buffers of the application to individual memory banks in the array of data processing engines; and translating the detailed mapping to a file.

Data processing engine (DPE) array detailed mapping

An example method for compiling includes, by a processor-based system: obtaining a netlist of an application, the netlist containing program nodes and respective edges between the program nodes, the application to be implemented on a device comprising an array of data processing engines; partitioning the netlist into a plurality of partitions; for each of the plurality of partitions: generating a global mapping of the program nodes based on a representation of the array of data processing engines and using an integer linear programming (ILP) algorithm; generating a detailed mapping of the program nodes based on the global mapping; and translating the detailed mapping for each of the plurality of partitions to a file.

Netlist partitioning for designs targeting a data processing engine array

Clock region partitioning and clock routing includes creating partitions for a plurality of clocks of a circuit design, and legalizing the partitions using a processor according to a number of clocks in each partition and assignment of clock distribution tracks. Roots for implementing clock trees of the clocks are selected within the partitions.
