To use the MT8870 in your simulation, you must manually add the library files (typically files) to your Proteus installation: How to Add Arduino Library in Proteus 8 [100% Working] 28 Nov 2020 —
The MT8870 Proteus Lib 35 offers several benefits to designers and engineers, including: The MT8870 is a complete Dual-Tone Multi-Frequency (DTMF)
Lower the animation sampling rate in the Proteus system settings or reduce the overall simulation runtime window.

Even with the library installed, simulations can sometimes hit a snag. Here are solutions to common problems and some alternative methods to consider.
Ultimately, for mission-critical projects involving DTMF decoding, the most reliable method is often physical prototyping with the real MT8870 chip, followed by refining your design based on those results. However, for initial code validation and proof-of-concept schematics, the community workarounds are a powerful tool. By demystifying the "lib 35" challenge, you have the knowledge to navigate these simulation waters and bring your touch-tone controlled projects from concept to reality.
