Abstract: A method of configuring a programmable integrated circuit device. A channel source within the virtual fabric is configured to receive input data from a first kernel outside of the virtual fabric and on the programmable integrated circuit device, and a channel sink within the virtual fabric is configured to transmit output data to the first kernel. The configuring of the channel source is modified such that the channel source receives input data from a second kernel in response to detecting a change in operation of the programmable integrated circuit device.

Abstract: Systems and methods for dynamically adjusting programs implemented on an integrated circuit (IC) are provided. During runtime, characteristics of the application may change or become known. Accordingly, the embodiments described herein allow for partial reconfiguration of kernels implemented on an IC during runtime to dynamically alter performance based upon these characteristics.

Abstract: A method for designing a system on a target device is disclosed. A first netlist with a first set of functionally invariant boundaries (FIBs) is generated after performing extraction during synthesis of a first version of the system in a first compilation. One or more of the FIBs is invalidated from the first set after performing optimizations during synthesis in the first compilation resulting in a second netlist with a second set of FIBs. A third netlist with a third set of FIBs is generated after performing extraction during synthesis of a second version of the system having a changed portion in a second compilation. Connectivity of matching nodes from the first netlist and the third netlist reaching FIBs is traversed to identify equivalent nodes associated with identical regions. The identical region in the third netlist is replaced with an optimized synthesized region from the second netlist.

Abstract: A method for designing a system on a target device is disclosed. A first netlist is generated or a first version of the system in a first compilation. Optimizations are performed on the first version of the system during synthesis resulting in a second netlist. A third netlist is generated or a second version of the system in a second compilation. The first version of the system in the first netlist and the second version of the system in the third netlist are differentiated to identify identical regions.
