Dynamic Function eXchange Bitstream Monitor


Product Description

The Dynamic Function eXchange (DFX) Bitstream Monitor can be used to identify partial bitstreams as they flow through the design. This information can be used for debugging or to help manage system applications such as blocking bitstream loads. Identifiers embedded at key places in partial bitstreams are extracted are reported by the core. This information can be passed to Vivado HW Debugger using an ILA core to work out what partial bitstream was fetched, if it was fetched in its entirety, and how far through the datapath it went.

This core is intended for enclosed systems where all of the Reconfigurable Modules are known to the controller. The optional AXI4-Lite register interface allows the core to be reconfigured at run time, so it can also be used in systems where the Reconfigurable Modules can change in a deployed system.  The core can be customized for number of Virtual Sockets, number of Reconfigurable Modules per Virtual Sockets, operation and interface.
