# Build the engine's bitstream and convert it for the Linux FPGA manager. Needs the vendor's tool on
# PATH, at the version this design was built and measured with: Vivado 2026.1 (landscape.tcl stops on
# any other). Its no-charge licence tier covers this part. The design uses no licensed IP: its vendor
# blocks are the processing system's configuration and, in the AXI build, the tool's AXI width and
# protocol converters. Run from an empty directory:
#   sh /path/to/wai-quantum-landscape-fpga/scripts/build_bitstream.sh [MHz] [cores] [axi|emio]
# The AXI link is the default; the multi-core build (cores above 1) has the EMIO link only.
# JOBS (default 4) is how many tool runs go at once. On a small machine, run with JOBS=1 and a memory
# cap: the tool peaked at 5.1 GB alone, and a machine with 15 GB shared with other work ran out.
