New ContributorCan you have non-altera devices in the Intel Quartus Prime Software JTAG Chain?
You can add other devices (non-Intel/Altera) through the programmer. Open the programmer then select the "Add Device" button on the left side. A dialogue should appear that allows you to pick from existing devices. Use the "New" and/or "Import" buttons in that dialogue to add new devices. Essentially the programmer needs to know the device's JTAG ID, instruction register length, and the name you want to give it. Once you do that (assuming you get the JTAG ID right) the programmer will recognize the device and automatically issue a JTAG bypass instruction when it appears in a chain.
New ContributorI took a day to research this in-depth and I have answered my on questions. The USB Blaster in JTAG mode using the Quartus Prime Programmer only allows Altera devices to be detected. I didn't try but I don't think you can even load a non-Altera devices BSDL file and have the programmer to skip it. I had to manually (in the Hardware using resistors) bypass the non-Altera devices in the JTAG Chain to get the Quartus Programmer to Auto-Detect the Altera devices.
So, if you have a JTAG Chain with Altera and Non-Altera devices please add a convenient way (jumpers) to bypass and include devices.
