According to some embodiments, a method is provided for simulating an analog and mixed-signal circuit design comprising an analog circuit segment connected to a digital circuit segment at a connection point, the method comprising: inserting a bi-directional interface element at the connection point, wherein the analog circuit segment connects to an analog port of the bi-directional interface element and the digital circuit segment connects to a digital port of the bi-directional interface element; and operating the bi-directional interface element such that the bi-directional interface element detects a signal direction and, according to the signal direction, either converts a first analog signal received from the analog port to a first digital signal for the digital port while maintaining a first signal strength of the first analog signal, or converts a second digital signal received from the digital port to a second analog signal for the analog port while maintaining a second signal strength of the second digital signal.
