P9027LP-R-EVK Layout Guide

Using the Reference Layout
The P9027LP-R-EVK reference layout is a full feature four-layer design optimized for high-performance, small-size, and ease-of-use. The
purpose is to minimize design-in effort and risk by providing a proven solution that can be imported into an existing system design. The
P9027LP-R-EV board layout can be divided into two parts; the main function layout (core layout) and the layout for test purpose. When
imported into an existing system, only the core layout is necessary. The core layout follows the design rules for wearable devices with
minimum space and trace width of 4 mils. The minimum finished VIA size is 4 mils, assuming 1 mil plating thickness. The minimum spacing
between components is 0.2 mm. Only through hole VIAs are used. There are no blind or buried VIAs. When circumstances permit, it is highly
recommended to copy the reference layout.
Importing the Reference Layout
The P9027LP-R-EVK reference design was created using Cadence PCB design software. This software has been used to generate the
layout modules, which can be rapidly deployed onto PCB designs, using Cadence, OrCAD, CIS and Cadence Allegro PCB Editor. The
P9027LP-R layout module is labeled P9027LP-R-EVK.mdd and may be loaded into an existing or new PCB design file by following these
instructions:
1. Use or copy the P9027LP-R-EVK schematic file (.dsn) and export the netlist to a PCB file.
2. Move the file P9027LP-R-EVK.mdd to the same directory as the PCB design file.
3. Import the netlist into the PCB file (.brd).
4. Open the PCB design file (.brd) and click on the menu PlaceQuickplace…
a. Select Place by Page Number and select the page the P9027LP-R circuitry resides on
b. Click Place. Click Ok..

5. Select the parts that were placed from the schematic that matches the schematic used from the P9027LP-R-EVK.
a. In the Find Filter, select Symbols, then left click and drag to highlight all of the components that were just placed.
b. Right click on any of the highlighted parts and select “Place Replicate ApplyBrowse…”.
c. Select the P9027LP-R-EVK.mdd file and select Ok.
d. Components should now be matched; if unmatched, manually identify and match component reference designators based
on schematic location.
6. Enter the coordinates(x,y location) in the command window where the P9027LP-R circuit should be located at, or left click where the
P9027LP-R should be placed.
