Since September of 2001, the SignOnce IP License has been the industry's first and only set of common license terms for programmable logic soft IP cores. Xilinx and leading third-party providers have agreed to offer cores to FPGA customers under a common set of terms known as the SignOnce IP License thereby simplifying the process by which customers can access IP from multiple suppliers. This page provides access to example license forms, membership and additional information.
If you are an IP provider and would like to simplify the licensing process with your end customers, then we invite you to join the growing list of worldwide companies who support the SignOnce IP License. SignOnce members are not required to also be members of the Xilinx Alliance Program or vice-versa. You may contact us by using the link below.
