Anyone know how to read the device JTAG User Code (Electronic Signature) from Nios II? thanks!

I presume you mean the usercode which is part of the device configuration and is stored in the SOF file.

Unfortunately there is no way for logic within the chip to see this usercode as it can only be accessed via the JTAG pins on the chip.

Sorry.

But you can get a lot of the benefits of a usercode using a system ID peripheral. Please tell us what you're trying to do if the system ID peripheral doesn't meet your needs.
