Device Libraries

Overview

The OpenTitan repository contains device libraries which are used within our Reference Firmware Images, and can (and should) be used by other OpenTitan device software.

These are organised into the sw/device/lib directory.

• sw/device/lib/base contains the Base Libraries, including freestanding C library headers. The Base Libraries are simple libraries that can be used by any other OpenTitan device software libraries.
• sw/device/lib/dif contains the Device Interface Functions.
• sw/device/lib/arch contains the libraries to be used on specific device configurations (for instance FPGA, Simulation, etc.).
• sw/device/lib/runtime contains general libraries for more advanced on-device functionality (including logging, printing, and interacting with the RISC-V core).
