Quartus-II and APEX20K160E

Hi I am trying to save the configuration file from an APEX20K altera device using jtag interface. I am using the Quartus-II software and USB blaster cable. I can see the JTAG chain, but I cannot see ...

Dave,

Thanks for the good info. In my board I have a EPM7032AE device also in the chain along with this APEX IC. Is EPM7032AE a volatile flash that can load the APEX with the data?

Thanks

The FPGAs are volatile, they are programmed at power-on by a configuration device. The EPC2 device FvM mentioned is basically a non-volatile flash that is used to program the FPGA.

You can reprogram the FPGA using JTAG while the power is on, and when you cycle power, the old configuration will reload from the EPC2.

You can change the FPGA configuration permanently by reprogramming the EPC2.

The APEX20K devices are old. I think you will need to use Quartus II 9.0SP2 to generate programming files.

Cheers,

Dave
