7 years agoHi,
--- Quote Start --- the temperature read from the internal sensor is garbage (the offset differs from board to board but is typically reporting 10 - 20 degrees C too low). The ADC is being clocked at 40 MHz from the onboard PLL, which is itself clocked from a 12 MHz source. I have tried disabling all channels except the TSD and this makes no difference and have also tried using a slower ADC clock and internal and external reference options all to no avail. --- Quote End --- To see huge diffrence in temperature reading, run board for longer time by utilizing most of the FPGA resourceor or by using test setup like ESS or simply using blower. --- Quote Start --- cannot find anything to suggest that I should not use 3.3 V for bank 8. Have I missed something? (FYI, bank 8 was moved to 3.3 V to make it easier to interface the configuration clear and done signals to a USB interface chip fitted to the new board.) --- Quote End --- It is based on your design kindly check example 3 & 4 in below link. https://www.altera.com/en_us/pdfs/literature/dp/max-10/pcg-01018.pdf Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
