`Ibex <https://github.com/lowRISC/ibex>`__ is a parameterizable RV32 embedded core written in SystemVerilog, currently maintained by lowRISC. `Ibex <https://github.com/lowRISC/ibex>`__ is a parameterizable RV32IMC embedded core written in SystemVerilog, currently maintained by `lowRISC <https://lowrisc.org>`__.
The `Ibex core` is wrapped in an `Ibex tile` so it can be used with the `Rocket Chip SoC generator`. The `Ibex core` is wrapped in an `Ibex tile` so it can be used with the `Rocket Chip SoC generator`.
The core exposes a custom memory interface, interrupt ports, and other misc. ports that are connected from within the tile to TileLink buses and other parameterization signals.

While the core itself is not a generator, we expose the same parameterization that the Ibex core provides so that all supported Ibex configurations are available.
