1 General Info on Layout Design VS10xx family devices have separate analog and digital power net and grounds. Most of the devices also have separate power net for the DSP core. Devices have several power and ground pins. To obtain best performance the layout designer must know to connect these pins properly. The purpose of this document is to suggest good design practices. Each chapter in the application note has a picture describing the part of the layout that the chapter covers. Top layer is red and bottom layer is blue. For sake of clarity silk screen is not included in the detailed pictures. A schematic of the example （figure 1） and picture of the complete layout （figure 6） are also provided. Notice that this is not a working application but an example of good layout design.
