EPM7128STI100(MAX7000S): The POF file data contents are converted to jtag's SDR

Hi WolfGang,

I know how to use the Quartus Programmer to convert a POF into an SVF file and verify chip.

​

However, I want to support this chip in my own programmer.

Converting to SVF files is just to understand the chip programming process.（The second half of the svf file programming and the "verify" part did not understand）

I want to know how to convert the contents of a POF file into the corresponding data of a JTAG instruction. That is how to write the POF file into the chip through JTAG and verify？

Thanks.
