FPGA Configuration using Multiple PROMs

Hello all,

In my recent projects, I was using the V4 device (quite a huge one) and it required two 32MB Platform Flash to configure. To generate the corresponding MCS file, I pulled in two 32M in Impact GUI which as a result automatically generated the mcs and shared it in 2 labelled mcs0(100% used) and mcs1(33% used). Now when I wanted to program them on the board, during the boundary scan, it found the 2 PROMs on the board but however I was not sure in which order should i load the mcs (mcs0 to the left and mcs1 to the right one or the other way). Though I have the schematic, I could not figure out much except that that 2 PROMs are connected in daisy chain along with the FPGA. Ofcourse by trial and error I figured out (thanks to the working code), I was wondering if some of you could share your thoughts as well.

Thanks in advance, Venkat.
