General Description: I've recently obtained Foundation ISE 3.1i, or Foundation Classic 3.1i. Do I need a new license for FPGA Express?
ソリューション
No, the same license file that enabled you to use FPGA Express 3.2 and 3.3 will enable you to use FPGA Express 3.4 which is packaged with 3.1i Foundation (ISE or Classic) software.
