Cmos galvanic isolation for preventing remote physical attacks in multi-tenant cloud fpga systems

A galvanic isolation circuit comprising:

• one or more tenant cores;
• a power management unit that is configured to select between an isolated power source or a board power source;
• a capacitor bank that is configured to isolate the one or more tenant cores by delivering one or more currents based on a power source selected by the power management unit;
• and
• a configuration controller unit that is configured to provide configuration data for managing selection of the power source.

An isolated tenant logic block system comprising:

• an isolated power source;
• a complementary metal-oxide semiconductor (CMOS) that is coupled to the isolated power source;
• a plurality of tenant logic blocks that are configured to receive the isolated power source from the CMOS;
• and
• a multiplexer that is configured to modulate the isolated power source received by the plurality of tenant logic blocks from the CMOS.
