How to generate a jam file which supports the option of DO_REAL_TIME_ISP based on Quartus Prime 17.1?

Description

You may find the Jam file generated based on Quartus Prime 17.1 is different from the one converted based on early versions.  It may not have the option of DO_REAL_TIME_ISP for the programming of CPLD.

Resolution

Different from the earlier versions, you need to check the option "Enable real-time ISP to allow background programming when avaliable" in the programmer window. Then you can get a jam file which supports DO_REAL_TIME_ISP option for programming CPLD.
