Yes, exactly!  In fact, FPGAs are somewhat nicer in that only the
hardware actually needed is present on the running system (fewer data
instances), but the flip side is that the set of instances changes at
the whim of the FPGA engineer.  Static definition isn't an option
unless you want to change the platform source code for each new FPGA
bistream revision.
