SUMMARY
The discussion focuses on implementing a multiplexed ring oscillator system using FPGAs, specifically selecting between two asynchronous oscillators as clock sources. The key challenge is to ensure that the output states of both oscillators maintain their timing integrity during switching. The proposed solution involves using OR and AND gates to control the clock selection while ensuring that the first clock stops before the second clock is connected. The user emphasizes the necessity of testing and simulating the logic to validate its functionality.
