Can we do the boundary scan using the Quartus II programmer only or do we need external software for the scan.

    Unfortunately you will need to use external software to do it.

        Many boundary scan tools on the market. I'm using TopJtag as reported in previous post. Free time limited evaluation available. Support of USB Blaster and FT2232 based JTAG adapters, but not USB Blaster 2.

        There are also open source projects.
