Hello,
I have spent the last few days correcting the pin spacing on the
PQFP208 module, the pin spacing is now correct at 19.7 Mils.
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.
I want to try it out, is it at yahoo files? where?
Saludos, Juan Pablo.
Regards,
David.

Hi all, I hope that with this we can leave te "case closed":
With the attached script and this parameters: ./pqgen.pl 52 2 pq208
197
0 1000 100
I created a "ruller" for compare with the kicad package.
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 component
has
the pads from the ruller, the one
in the solder side is the one wich comes with kicad.
Saludos, Juan Pablo.
