Symbol: MOS_a2d

Interface Element for MOS - Metal Oxide Semiconductor Analog to Digital Convertor

A general Interface Element (IE) for mixed signal. To match your design, you will need to change the Base CDF. The default is for 5V logic. Do not manually place this component in your schematic as the IE placement is done automatically by the mixed signal netlister.

Symbol: TTL_a2d

Interface Element for TTL - Transistor to Transistor Logic Analog to Digital Convertor

An Interface Element (IE) for TTL that is used as an analog-to-digital interface for mixed-signal simulations. The analog-to-logic converter transfers analog waveforms to a logic simulator.
