Platform Manager
Development Kit
This document provides a brief introduction and instructions to install and run the Platform
Manager™ Development Kit on Windows 7/Vista/XP. Please refer to the complete
documentation at www.latticesemi.com/ptmdevkit for more information.
Check Kit Contents
The Platform Manager Development Kit contains the following items:
• Platform Manager Evaluation Board pre-loaded with Platform Manager Demo
• USB connector cable
• 5V DC wall adapter power supply
• QuickSTARTGuide
Static electricity can shorten the lifespan of electronic components. Please handle the
kit components carefully.
Power the Platform Manager Evaluation Board
Power the board by connecting the 5V wall adapter plug to the evaluation board.
Running the pre-loaded demos does not require connecting the provided USB cable
to a PC. The cable is required to modify the pre-loaded demo or to load additional IP
cores and reference designs.

In the following steps, the evaluation board will be powered and made ready to run the
preloaded demonstrations.

Platform Manager
Development Kit
Run the Platform Manager Demo
Initial board setup:
• Set all DIP switches in SW9 and SW10 to the up/off position.
• Set all DIP switches in SW2 to the on position.
• Set slide potentiometers (pots) R19 and R20 to the down position, toward the
center of the board.
• No jumpers should be installed.
Demo 1 – Test Board Power, LED D1, and All Power Supplies
Demo 1 shows the ability of the Platform Manager to monitor and sequence input power
railsandon-boardsupplies.TherearevesuppliesconnectedtoveseperateVMON
inputsonthePlatformManagerEvaluationBoard.Therstthreesupplies,5V,3.3V,
and 2.5V, are power rails that the Platform Manager does not enable; it is only monitors
them.Thesecond2.5VsupplyisanLDOthatthePlatformManagerenablesandthen
monitors, and the 1.2V supply is a DC-DC converter that the Platform Manager enables
and then monitors. There is also control from the Margin/Trim outputs on the Platform
Manager to each of these supplies. The table below shows how the four LEDs in the
display follow the progress of the monitoring, enabling, and sequencing.
• Plug the 5V wall plug supply into the board supply plug.
- The blue LED D1 is on and will remain on while the board is powered.
 -LEDsD21-D23cyclethroughsteps1-6asshowninthetablebelow.Failureto
cycle through the steps indicates a power supply error.

Demo 2 tests the position of the slide pots, and displays patterns and information on
theLEDsandLCDdisplay.TheslidepotsareconnectedtotwoVMONinputsofthe
PlatformManagerandaresettobe“good”atabout3V.Thedemochecksforbothpots
to be at good levels, then continues to the next step, which is to exercise various digital
outputs from the Platform Manager. Platform Manager outputs connect to the LEDs, as
shown in the tables below, and also to the LCD. The Closed Loop Trimming function for
theLDOandDC-DCconverterisalsoenabledatthispoint.

- The voltage across the two pins of J8 will measure 2.5V +/- 1%.
- The voltage across the two pins of J7 will measure 1.2V +/- 1%.
Demo 3 – Test DIP Switches SW9-SW10
Demo3continuestoexercisethedigitalinputsandoutputsofthePlatformManager.
Two of the DIP switches are connected to the digital inputs of the Platform Manager.
As these DIP switches are turned on or off, the LCD will display two hexadecimal digits
corresponding to the values produced by the four bits of each DIP switch.
• One by one, move DIP switches SW9-SW10 from the off/up position to the on/
down position, and then back to the off/up position.
- The LCD will display corresponding hexadecimal characters representing the
hexadecimal value of each DIP switch as it is moved. The value will change
  foreachswitchsetting,asshowninthetablebelow.Othervaluesmaybecreated
by depressing more than one switch at a time.
Demo 4 – Test All Segments of the LCD Display
SimilartoDemo3,Demo4alsousesdigitalinputs.Inthisstep,oneofthepush-buttons
which is connected to a digital input causes the LCD controller to display a looping
sequenceofnumbersfrom111-FFF.ThissequencerepeatsontheLCDaslongasthe
push-button is depressed.
• Press and hold PB_B_SW2.
- The LCD display will show a counting sequence from a blank display, through
  111,222,333…FFF,andwillrepeat.Thecountmaystartanywhereinthesequence.

Done!
Congratulations! You have successfully demonstrated the Platform Manager
Development Kit. Please refer to the Platform Manager Development Kit User’s Guide
available on the Lattice web site at www.latticesemi.com/ptmdevkit for the following:
• Running advanced demos, including voltage monitoring, via I2C
• Details on additional development board features and operation
• ModifyingandgeneratingthedemoprogramlesfromthePAC-Designer®
project sources
• Board schematics
• Gerber PCB layout artwork
Demo 5 – Test Two Push-buttons and Trimming/Margining
This demo shows the operation of the Closed Loop Trimming, and the ability of the
PlatformManagertohavedifferentvoltageprolesformarginingwhichareselectableon
they.Therearethreeprolesusedforthistest.Prole1generatesthetargetvoltage
(e.g.,1.2V)andadjuststheoutputvoltageupby5%.Prole2adjuststheoutputvoltage
downby5%.Pressingeitherofthepush-buttonsshownbelowselectsoneoftheproles.
• Press and hold push-button PB_A_SW1.
 -ThevoltageacrossthetwopinsofJ8willmeasureapproximately2.625V.
 -ThevoltageacrossthetwopinsofJ7willmeasureapproximately1.26V.
• Release push-button PB_A_SW1.
• Press and hold push-button PB_B_SW2.
 -ThevoltageacrossthetwopinsofJ8willmeasureapproximately2.375V.
- The voltage across the two pins of J7 will measure approximately 1.14V.
• Release push-button PB_B_SW2.
Demo 6 – Test Push-button S1 for Reset Function
Demo6illustratesthePlatformManager’sabilitytosequencethroughapower-down
scenario, and in this case, restart the demo. When push-button S1 is depressed, the
DC-DCconverterispowereddown,followedbytheLDO.Thesequencerthenreturns
to the beginning of the demo and starts over.
• Move Slide Pots R19-R20 to the down position (center of the board). Press and
release push-button S1.
- The board will reset and the test will start over.
