prMagic

Tools for automating the Vivado project partial reconfiguration flow. Developed as part of my bachelor thesis.

Instructions

1. Download the release package and extract the contents into your Vivado project folder
2. Include all your VHDL files into the project (preferably into the sources_1 file set)
3. Annotate your component instantiations with

--PRMODULE(<modulename>);

example:

--PRMODULE(anotherModule01);
--PRMODULE(anotherModule02);
--PRMODULE(anotherModule03);
myRegion01: primaryModule
port map (
  clk => clk,
  A => A,
  Y => Y_i2
);

4. Run "source prMagic.tcl" to load scripts
5. Run prm_main now to setup partial reconfiguration
6. Edit code and annotations, go back to 5.
7. Floorplan the partitions
8. Use Vivado as you would normally

Limitations

• Nothing but VHDL is supported in the hierarchy (no Verilog, IP-blocks, etc.)
• Keep every modules top level entity in a separate file
• Do not use the same entity in different partitions
• No entity instantiations for primary modules of partitions
• Aliases and libraries are not supported for module name resolution
