# Use a bitstream from the GCP bucket (this is also the default condition).
# You can control the GCP bitstream selection via the BITSTREAM environment
# variable.  See //rules/bitstreams.bzl for more information.

#   bazel test //sw/device/silicon_creator/lib/drivers:hmac_functest_fpga_cw310 --define bitstream=gcp

# Skip loading a bitstream in to the FPGA.  This is useful if you already
# have a bitstream loaded into the FPGA and you don't want the GCP cache
# manager to do anything unexpected.

#   bazel test //sw/device/silicon_creator/lib/drivers:hmac_functest_fpga_cw310 --define bitstream=skip
