+# This Makefile provides a streamlined way to create an example
+# FPGA interchange BBA suitable for placing and routing on Xilinx A35 parts.

+# FPGA interchange device database is generated via RapidWright.
+#
+# Currently FPGA interchange physical netlist (e.g. place and route route) to
+# FASM support is not done, so bitstream generation relies on RapidWright to
+# convert FPGA interchange logical and physical netlist into a Vivado DCP.
