JTAG Chain HPS and FPGA - Excluding HPS or FPGA via Jumpers - Cyclone V SoC

If microcircuit with JTAG-pins is soldered to board, it must be connected to common JTAG-chain without jumpers. Altera don't motivate their swithes ?

I dont see necessity of "user-conditional" including of device JTAG: always, even used insertable microcircuit/board, constructor may will determine its presence/absence and insert it to common JTAG chain with onboard logic.

All modern soft may access to any device in chain and in parallel/sequental to all its set, only various-Blasters need be a little less :)
