Eye XO and QED are both software tools used for circuit design and simulation, but they have some differences in their features and capabilities.
Eye XO is a web-based tool that allows users to design and simulate digital circuits. It has a simple and intuitive interface and supports a wide range of digital components such as logic gates, flip-flops, and arithmetic circuits. Eye XO also has a built-in simulator that can be used to test and debug the designed circuits.
