[fpga, sw] Enable SCA on ChipWhisperer CW310 FPGA board This involves the following main changes: - Two new outputs are defined on the CW310 chip-level to provide the target clock and capture trigger to the capture board. - The capture trigger can now be selected at run time through software and GPIO. This allows for taking SCA measurements for different IP cores (KMAC, OTBN) without having to re-generate a different bitstream. - The capture trigger is synchronized to the target clock (100 MHz). This is needed to prevent metastability issues in the scope depending on place and route on the target FPGA. - UART1 is enabled and muxed to pins IOC9/IOC8 using the pinmux. This is needed for the simple serial communication between target and capture board, while UART0 remains available for debug prints and logging. - The simple serial library is adjusted to use dif_uart_* only instead of a mix of dif_uart_* and base_printf() (this required the UART used for simple serial and stdout to be the same device previously).

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
