About this Repository

This code:

• Implements a ring oscillator in VHDL.

By modifying the layout of the gates on an FPGA, you can see a modification to the oscillation.

It may be an interesting project to se if you can bias the oscillations in a predictable manner, and thus have a "gateless" hardware trojan for TRNGs.

Trojaned_TRNG.vhd contains the top-level definition for the trojaned ring oscillator.
