Further, it allows for distributing designs in bitstream or FPGA format without accompanying it with a copy of the license. Developers are required to keep the core's source code confidential and use "for the sole purposes of design documentation and preparation of Derivative Works ... to develop designs to program Lattice programmable logic devices".
The provision enables distributing designs in bitstream or FPGA format without a license copy, while developers are required to maintain the core's source code confidentiality and utilize it solely for designing Derivative Works to program Lattice programmable logic devices.
