        with products.extract("{}.sof".format(name)) as bitstream_filename:
            # The @2 selects the second device in the JTAG chain, because this chip
            # puts the ARM cores first.
            # THIS IS FROM THE DE10 CORE AND IT DOES *NOT* LOOK RIGHT HERE !!!
            subprocess.check_call([quartus_pgm, "--haltcc", "--mode", "JTAG",

I don't see a toolchain_build. I assume that's in the IntelPlatform
