Vivado Design Suite User Guide: Dynamic Function eXchange (UG909)

2023.2 English

The Dynamic Function eXchange Project Flow inserts the key requirements of Dynamic Function eXchange into the existing Vivado project solution, accessible within the Vivado IDE as well as via Tcl commands. These key requirements include:

  • Defining Reconfigurable Partitions (RP) within the design hierarchy
  • Populating a set of Reconfigurable Modules (RM) for each RP
  • Creating a set of top-level and module-level synthesis runs
  • Creating a set of related implementation runs
  • Managing dependencies as sources, constraints or options are modified
  • Checking rules and results
  • Verifying configurations
  • Generating compatible sets of full and partial bitstreams

These fundamental aspects feature support for a front-to-back implementation for RTL-based designs including IP. Partial Reconfiguration (PR) terminology has been replaced with Dynamic Function eXchange (DFX) terminology. However, underlying Tcl commands have remain unchanged so that existing projects and scripts can safely migrate forward.

One expectation of this flow is that all sources (at least the top-level RTL and post-synthesis netlists for sub-modules) are managed within a single DFX-enabled project. A project cannot be broken up or exported, because the Vivado tools would no longer be able to track dependencies between runs and sources.
