6.
Using a DVM, measure DC voltages using TP11 as ground:
TP6 and TP7 – should be 3.3 V (values
±
0.2 V are acceptable). Values outside this range are a failure.
TP15 – should be 1.5 V (values
±
0.1 V are acceptable).
TP8 – should be 1.8 V (values
±
0.1 V are acceptable).
TP10 – should be 2.5 V (values
±
0.2 V are acceptable).
TP47 – should be 5.0 V (values
±
0.2 V are acceptable).
J14C pin 106 – should be 3.3 V (values
±
0.2 V are acceptable). Note that jumper JP48 must be in place for this
measurement, otherwise zero will be recorded.
7.
That completes the initial power-on check. The board should now be switched off by moving SW11 to the OFF
position (to the left).
Testing Board Functionality with A3PE600-PQ208 or A3P250-PQ208 Silicon
To test board functionality:
1.
Record the time of the test and the board serial number (written by the bar code on the back of the board) into a test
log.
2.
Make sure the switch SW11 is in the OFF position (i.e., to the left.)
3.
Apply power to the board by attaching the +9 V DC supply to J18. Only the red LED should be illuminated.
4.
Undo the four screws holding the socket of U8 in place. Remove the lid of the socket.
5.
Place a pre-programmed A3PE600-PQ208 or A3P250-PQ208 FPGA part into the socket using the appropriate
vacuum pen while observing anti-static precautions. Make sure that pin 1 of the FPGA is oriented correctly. (The
Actel logo on the part should match the orientation of the Actel logo on the board just above the A3PE-A3P-BRD1
part number.) Take great care to make sure all pins are in correct alignment so that the FPGA is on a level plane
parallel to the board.
6.
Carefully replace the socket cover and screw down all four corners to appropriate tightness. It is recommended to do
opposite corners first so as to lessen rotational torque on the part.
7.
Switch on SW11 to the ON position (slide it to the right).
8.
Validate that all 5 LEDs at the top of the board including the red one turn on. D17, D11, D10, D9, D13, and D19.
9.
Validate that the 8 LEDS: D8, D7, …, and D2, D1 all pulsate in either a counting pattern or a “center to outside
swinging” pattern.
10.
If no LEDs are visible, stop and switch off SW11. Rotate SW8 and SW9 clockwise to the 3.3 V selection. This is
best described with the thicker arrow bar pointing upward. Switch the board back on. The LEDs should be visible.
If very dim, stop, switch off the board and rotate the switches one quarter turn clockwise before switching board back
on. Continue if the LEDs are glowing. If unable to get a display on the LEDs, the board must be tagged as bad.
11.
If it is a bad board, carefully remove the A3PE600-PQ208 or A3P250-PQ208 silicon from the socket and set it aside
in an electrostatic-safe area. Using another piece of pre-programmed silicon, repeat steps 4 to 8 above.
If still no response, mark the board as defective and re-use the silicon for other testing.
If there is a good response, then place the previous silicon in a “bad” tray to prevent it from being retested.
12.
Validate that the patterns can be switched by pressing SW6 (Global pulse) on the left side of board. When the
switch is pressed, the LED D15 should momentarily light. The pattern on the 8 LEDs D8 through D1 will change.
13.
Validate that the message “Actel A3PE Starter Kit” continually cycles on the LCD display. You may need to turn
R40 clockwise to adjust contrast on the display until the message is dark enough to see.
If no message is observed, press buttons SW4 and SW3 simultaneously. This will usually reset the system after a
few cycles of the counter.
14.
Connect a FlashPro3 programmer to a PC USB port and observe the power light illuminating. Ensure that the
FlashPro v3.3 software is installed on the PC being used.
