Techniques for enforcing configuration requirements for application-specific integrated circuits (ASICS)

A system of operating a system-on-chip (SoC), the system comprising:

• one or more processors;
• and
• one or more non-transitory computer-readable media storing computer-executable instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• receiving, by an isolated Root of Trust (ROT) code, an indication of a persona associated with the SoC, wherein the SoC is associated with a first configuration that assigns a first physical input/output pin of the SoC to a first functionality associated with the SoC and a second physical input/output pin of the SoC to a second functionality associated with the SoC;
• based on receiving the indication of the persona, modifying, by the isolated ROT code, configuration data associated with the SoC, wherein modifying the configuration data comprises configuring a pin multiplexer of the SoC to:
• disconnect the first physical input/output pin from the first functionality and connect the first physical input/output pin to the second functionality, and
• disconnect the second physical input/output pin from the second functionality and connect the second physical input/output pin to the first functionality;
• subsequent to modifying the configuration data, enabling the SoC to operate in accordance with the configuration data;
• determining, by the isolated ROT code, a first operational environment by monitoring the SoC;
• determining, by the isolated ROT code, that the first operational environment is incompatible with a second operational environment associated with the persona;
• and
• modifying the configuration data to disable a third functionality, wherein the third functionality is associated with the first operational environment but lacks association with the second operational environment.
