Quartus JTAG Programming Issue

--- Quote Start ---

Hey guys,

I'm using the Max II CPLD (64 macros). After I program (using the Byteblaster II) the chip, Quartus says it finished and verified that the CPLD was programmed. However, when I look at the signals from the chip on an oscilloscope, nothing has changed since I programmed it last (a few weeks ago). All I/O pins are assigned in my design and pin planner files. Can anyone maybe point me in the right direction?

Thanks,

Joe

Hi Joe,

what kind of change do you expect ?

Kind regards

Hi,

The signal it was putting out was not what I had expected (and apparently Quartus as well because the simulation came out differently). So I tried loading a hopefully corrected version of the program but I got the same result. I was curious to see if it was actually programming the chip so I just set the output pins to vcc and loaded it onto the chip. The signal it put out afterwards was still the original program I had a couple of weeks ago when it should have been just high.

I appreciate the help.

Thanks,

Joe
