PS and JTAG combination
Is there any way I can combine PS configuration and JTAG into one connector only. I have very limit space and not able to consider to separate connectors for each way based on Intel cyclone IV development board design.
Thanks

Hi,
Refer application note AN 656
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/an/an656.pdf
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

Thanks Anand,
it was really helpful document.
I have one more question:
in Figure 2 in the document you sent, does not talk about pins: nCONFIG, CONF_DONE and nSTATUS connections in MAX10 configuration. I believe I should follow the figure 12 in MAX10 config document https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/max-10/ug_m10_config.pdf in page 35 for these pins. Is that correct?
Thanks

Hi,
Yes, you are correct. we can ignore TRST pin for EP4CGX30 FPGA.
The TRST pin is an optional active-low, asynchronous reset input used for Joint Test Action Group (JTAG) boundary-scan testing (BST). While the
TRST pin can be helpful in systems that use it, it is unnecessary for the successful operation of the BST circuitry in Intel devices. download cable does not use this pin.
