cyclone V device 5CSXC6C6U23C8NES is supported in which Quartus software version?

Hi,

Thanks for sharing information​,

Can you just open command prompt/terminal and type quartus_pgm --auto or jtagconfig.

And check if you can see any of below messages.

1. Error (213013): Programming hardware cable not detected May be due to download cable problem, TDO is not connected properly, a noisy TCK signal, or TDI shorted to GND, pull-up and pull-down resistors connected to the JTAG. USB Blaster problem replace USB cable /Blaster kit or installation issue reinstall Quartus which will install the drivers.
2. USB-Blaster II [USB-1] Unable to read device chain - JTAG chain broken

Monitor the signals like nStatus Conf_Done and others.

Check with GUI instead of command prompt or terminal for simplicity.

Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Best Regards,

Anand Raj Shankar
