Blanking bitstreams are generated and named just like standard partial bitstreams, as the black box variation is simply saved as another configuration checkpoint.
Clearing bitstreams. Unlike the bitstream types noted above, this type is specifically for UltraScale devices only. A new requirement for this architecture is to clear an existing module before loading a new module in. This clearing bitstream prepares the device for delivery of any subsequent partial bitstream for that Reconfigurable Partition by establishing the global signal mask for the region to be reconfigured.
Although the existing module technically is not removed the current logical module remains , it is easiest to think of it this way. They do not change the functionality, but must be delivered between partial bitstreams.
Each clearing bitstream is built for a specific Reconfigurable Module and must be applied after that module has been used, and must be sent to the configuration engine immediately before the next partial bitstream is delivered.
For example, to transition from module A to module B, the clearing bitstream for A must be delivered just before the partial bitstream for B is delivered. To transition from module B back to module A, the clearing bitstream for B must be delivered just before the partial bitstream for A is delivered. This is the case even if any partial bitstream in question is a blanking bitstream. Skip to Navigation Skip to Main Content. Internet Explorer is no longer supported by Xilinx.

Click here for information on Partial Reconfiguration in the Vivado Design Suite Partial Reconfiguration is the ability to dynamically modify blocks of logic by downloading partial bit files while the remaining logic continues to operate without interruption.
Partial Reconfiguration Software. Make sure the resources preview box shows the same numbers. In the next prompt, make sure that all available resources and the Assign selected cell box are checked.
This will ensure that all the resources in the Reconfigurable Partition are automatically reset every time a new module is loaded into this region. Run the following command in the Tcl Console at the bottom:. Finally, we set the HD. Run the following command in the Tcl Console :. At this point, the tools will check for a valid license for Partial Reconfiguration see screenshot below. Now save the constraints by left clicking the disk symbol at the top of the screen. Note that the icon for the image filter module has changed again after assigning a Pblock to the module.
Exit Vivado. The following files are generated in this tutorial and will be used in step In this step we will run a project-less, script based Vivado flow for Partial Reconfiguration. We define Reconfigurable Modules and Configurations in a tcl file. We link the RMs to the already synthesized static logic and implement each Configuration. Finally, we generate full bitstreams for each Configuration and partial bitstreams for each Reconfigurable Module.
We are using the following source files and output products from steps 4 and 5 as inputs in this step. We are looking at excerpts of the design. This code snippet sources the Vivado PR tcl scripts and makes the corresponding routines available. This code snippet sets up the target part, package and speed grade for implementation.
This code snippet sets up some basic variables to control the PR flow and where the input and output directories are located. This code snippet defines the static logic of the design. Synthesis will not be run on this module since we already have a synthesized design checkpoint available from step 4.
The RM instance name in the design hierarchy black box module is defined at the bottom. OOC synthesis is run on each of the RMs. This code snippet defines three Configurations, one for each RM.
Note that the first configuration has the static module set to implement whereas the second and third Configurations have it set to import under the partitions attribute. The static logic only needs to be implemented i.
