parameters:
  # XXX: This parameter needs to be absolute, or relative to the *.runs/synth_1
  # directory. It's best to pass it as absolute path when invoking fusesoc, e.g.
  # --SRAMInitFile=$PWD/sw/led/led.vmem
  # XXX: The VMEM file should be added to the sources of the Vivado project to
  # make the Vivado dependency tracking work. However this requires changes to
  # fusesoc first.
