Hi all,
Target : MAX10 - 10M02DCV36I7G Quartus: 15.1 We are trying to design a very minimalist and small MAX10 FPGA board using the 10M02DCV36I7G. The schematic (attached) of the board is very simple and only implement the following features :- Single 3.3V supply power : VCCIO3_5_6 = VCCIO_1_2_8 = VCCA = VCC_ONE and are all connected to a single 3.3V LDO regulator
- We aim to implement a SPI compatible bus. Considering the small amount of IO on this chip we decided to use the JTAG Pins Sharing features
- The FPGA is clocked with a 50MHz Resonator
- And a small led is connected to one of the digital I/O
- Other IO are connected to board pins or left unconnected
- Double check the schematic (cf . schematic.pdf (https://www.alteraforum.com/forum/attachment.php?attachmentid=13793&stc=1&d=1498221708)) and
- Verify FPGA schematic pin assignment using the pin table (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/dp/max-10/10m02dc.xls) and pins connections guidelines for max10. (https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/dp/max-10/pcg-01018.pdf)
- We already used a very similar schematic for a 10M02 EQFP144 that have been validated with working board.
- Re-Checked pin order between our PCB Footprint and Quartus Prime Pin Planner view founding no differences. (cf. pinnout-comparison.pdf (https://www.alteraforum.com/forum/attachment.php?attachmentid=13793&stc=1&d=1498221708))
- Asked the manufacturer which sort of test they performed: Their answer “all the board passed assembly optical inspection (aoi) and solder paste inspection (spi)”. So apparently it shouldn’t be a soldering issue.
- Unsuccessful JTAG chain test with the board connected to a 450mA – 3.3V power supply.

Is the device orientation correct? What solder paste stencil and aperture did the CEM use for the BGA? My money is on a short, regardless what the CEM stated about AOI - that can't see under the device. Can they X-ray the device for you?

10M02DCV36I7G is a dual supply device.
