Store version number of programming file

Hello, I would like to know if there is a better way of doing the following. In my design I have an FPGA interfaced with a DSP. I would like to be able for the DSP to read some kind of register on the FPGA that would return the version number of the fpga program file (.sof) that is currently used on the device. Also, maybe it could return the CRC of program file. I was just wondering if there is some mega function that I could use where I could read and it would return a version number and CRC?

I could create a constant and enter in some kind of number and then have that tied into a DFF which the DSP could read but I thought there might be a better way of knowning what version of FPGA code is running.

Thanks,

joe
