.sof is not genrated (urgent)

.sof is not generated. We have used megacore FFT function to build in to an IP of Qsys..it is generated without any error. but when we include this IP in our top level .sof and is not generated even ...

What do you have in the "Messages" section of the assembler report?

From your screenshot we know that you don't have the license for the FFT core. You can either buy the license, or try your design in evaluation mode.

I found the setting you need... go to Assignments > Settings > Compilation process settings > More Settings... and check the value for "Disable OpenCore Plus hardware evaluation". If it is "On" then no .sof file will be generated. If it is set to "Off" (the default) then you will have a xxx_time_limited.sof (where xxx is your project name).

When programming the FPGA with that time limited sof file, you will see a window saying that you are in OpenCore evaluation mode. Don't close that window or the FFT core will stop working.
