Introduction to OpenTitan 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 …

Universal 2nd-Factor Security Key When used as a security key, OpenTitan implements the Universal 2nd Factor (U2F) authentication standard, using a Universal Serial Bus (USB) 1.1 interface to …

Here is a list of all documented struct and union fields with links to the struct/union documentation for each field:

The IP should have self-test functionality to assess the health of the storage and analog structures. The IP may contain native PUF-like functionality.

Theory of Operation The following sections give an overview of the life cycle function. It begins with life cycle sensing at power up, progresses through how life cycle transitions are made, and then focuses …

Programmer’s Guide Pad Attributes Software should determine and program the pad attributes at startup, or reprogram the attributes when the functionality requirements change at runtime. This can …

PWM DV document Goals DV Verify all PWM IP features by running dynamic simulations with a SV/UVM based testbench Develop and run all tests based on the testplan below towards closing …

Phase and Duty Cycle Representation The PWM IP creates series of pulses with the desired on-off duty cycle. The duty cycle, DC, is typically expressed a fraction of pulse duration, d, over the period …

Interfaces Referring to the Comportable guideline for peripheral device functionality, the module flash_ctrl has the following hardware interfaces defined Primary Clock: clk_i Other Clocks: clk_otp_i …

The following sections give an overview of the life cycle function. It begins with life cycle sensing at power up, progresses through how life cycle transitions are made, and then focuses specifically on …
