Application Hardware Modeling
AHM simulation of the Pop-up Noise
Pop-up is an audible glitch in audio applications, which has multiple sources at different levels (ViC, SoC, PCB). This phenomenon really damages the listening comfort as pop-up is an unpleasant noise which reduces the perceived quality of the audio system by end users.
Today, there is no solution to completely avoid Pop-up Noise (PuN). However, acceptance levels should be defined with thresholds not to overpass. If you notice that PuN is too high on your prototype, a complete diagnostic will be required to find where it comes from, thereby increasing the cost as well as the time-to-market of the final product.
By performing an AHM simulation of the audio function of the system with SMASH, you will be able to analyze the PuN level of the system for a given application schematic and to proceed with the necessary changes to optimize the application schematic.
