FLOW CONVERGENCE DURING HARDWARE-SOFTWARE DESIGN FOR HETEROGENEOUS AND PROGRAMMABLE DEVICES

For an application having a software portion for implementation in a data processing engine (DPE) array of a device and a hardware portion for implementation in programmable logic (PL) of the device, an implementation flow is performed, using a processor executing a hardware compiler, on the hardware portion based on an interface block solution that maps logical resources used by the software portion to hardware of an interface block coupling the DPE array to the PL. In response to not meeting a design metric during the implementation flow, an interface block constraint is provided from the hardware compiler to a DPE compiler. In response to receiving the interface block constraint, an updated interface block solution is generated, using the processor executing the DPE compiler, and provided from the DPE compiler to the hardware compiler.
