How does limited time .SOF file work ?

Hi Imad,

During Intel FPGA IP Evaluation Mode, the Compiler only generates a time-limited device programming file (<projectname>_time_limited.sof) that expires at the time limit. Yes unfortunately it is one-time limited only and if you want to use your code after the evaluation time has expired, you need to buy the IP core implemented in your programming - otherwise you won't be able to program your FPGA. You can refer to link below for details

Thanks,
