# This target does not produce a non-zero exit code if detailed or global
# placement fails. In this case $(RESULTS_DIR)/3_place.odb and $(RESULTS_DIR)/3_place.sdc
# are produced, such that an artifact can be created for inspection purposes.
#
# The check-place target subsequently will fail if
# placement did not complete successfully, because $(RESULTS_DIR)/place.ok
# is set to 0.
#
# This means that build systems, such as Bazel, that require a non-zero
# exit code and the same artifacts to be produced every time, or it
# will not publish the artifacts, can use this target.
