If anyone is interested I will upload the modified module file. I did the editing by changing the co-ordinates directly in the libcms.mod text file.To do this I wrote a small c++ file to generate the co-ordinates to a file.I then used another parsing program to replace each incorrect line in the original module file with the modified line.Finally I fired up the module editor and checked the spacing.The package outline will need slight ajustment, but that is easily done by moving/extending a few lines.The critical thing is that the pads are now spaced correctly. The only thing that remains is to print out and test it on the actual device. Please let me know if anyone would like to try this out also. Saludos, Juan Pablo.

According to a datasheet from Xilinx PK007 (v1.2) June 18, 2004 about the PQFP (PQ208/PQG208) Package the space betwen pads should be 19.68503937 in mills of inches, i used 197 (rounding) for this ruller. When comparing on the screen this ruller with the package that comes with kicad i can see that the pads are not perfect, the differences varies from pad to pad, and some in the middle ar ok. So (lucky me!) i think the package will work with no problems. From here to 2 to 3 weeks (:-P) im going to have a board designed with this package. Then ill tell you the real thing: if it works or im fired.... Ive also attached a board with two modules, the one in the componenthasthe pads from the ruller, the one in the solder side is the one wich comes with kicad.
