Not that it makes much difference to
Charles' points regarding licensing, but for this board the core is
"fully hardened" - implemented in silicon using a TSMC 180nm process and
running at about 300MHz, with JTAG and debug and so on. 

The confusion
is understandable, as RISC-V is also available as a soft core, and 1,680
processors have been implemented inside a single (eye-wateringly
expensive) FPGA, complete with a Network-on-chip infrastructure...
