Helion

Legal fence

Helion is an original FPGA family and CAD, not a wrapper around a vendor tool. Vendor user guides are a checklist of capabilities, not a source tree to copy. Device facts come from HAD, never hardcoded in the CAD. No vendor bitstream.

Do not add Project X-Ray, vendor Tcl, UNISIM names, or 7-series / UltraScale / Lattice / Intel bitstream backends.

Do not ship AXI interconnect as Helion IP. The buses are Helion-MM and Helion-ST.

Do not use vendor trademarks as product names in the UI or docs.
