VHDL Source Folders
core
This folder contains the core VHDL files for the NEORV32 CPU and the NEORV32 Processor.
When creating a new synthesis/simulation project make sure that all *.vhd files from this folder are added to a
new design library called neorv32.
⚠️ The sub-folder core/mem
contains the platform-agnostic VHDL architectures of the processor-internal memories.
You can replace inclusion of these files by platform-optimized memory architectures.
processor_templates
Contains pre-configured "SoC" templates that instantiate the processor's top entity from core.
These templates can be instantiated directly within a FPGA-specific board wrapper.
system_integration
Top entities in this folder provide the same peripheral/IO signals and configuration generics as the default
processor top entity from core, but feature a different interface type.
For example: an AXI4-Lite-compatible bus interface instead of the default Wishbone bus interface
or a top entity with resolved port signal types.
test_setups
Minimal test setups (FPGA- and board-independent) for the processor. See the README in that folder for more information. Note that these test setups are used in the NEORV32 USer Guide.
