I have one more question about .sof and .pof files, I remember we used .pof file at school, I know .pof is Programmer Object File and .sof SRAM Objet File but, files are indifferent of the configuration scheme used? what is the relationship between files and configuration schemes?

.sof is the file you configure the FPGA with via JTAG.

That same file can be converted to other formats for an external programmer, eg., .rbf format, Jam STAPL format, etc.

My experience with .pof files is that they are the configuration files used when programming EPC2 configuration EEPROMs, so they are basically .sof files reformated to whatever is required by the EPC2 device.
