Hi all.
I'm stopped. Lattice Diamond does not offer a configuration for designing w ith my part in the 48-VFQFN package. The LCMXO2-640HC-6SG48I is not availab le in the drop-down configuration menu. They say the closest they can get i s the TQFP-100 or CSBGA-132 packages. My PCB and FPGA arrived days ago but I need a way to do development! Is there a way to configure Lattice Diamond so that it supports this 48 pin QFN device, please?
Thanks!

What version of Diamond do you have? Maybe you need to update?

Hi Rick. Well, heck. I'd downloaded and patched 3.9 and assumed that the ic on on my desktop was linked to the latest version. I was linked to 3.6 inst ead. I see that my 3.9 *does* support the QFN48 package. Is my face red or what. Thanks! --Len
That is both useful and annoying all at the same time. Sometime back I found by accident that when one upgrades Lattice Diamond it really doesn't update the software but install a new version while the original version is still there. Nice if you want multiple versions but if you don't it's confusing and eats extra space, so now I uninstall the old Lattice Diamond before installing the new version, and I keep the license in a separate folder from the software.

I can't see your face, so I don't know what color it is... lol
I noticed some time back that Lattice installed each new version in a new folder and does not delete the old version. Personally I think this is a
*very* good thing so that if something in your code breaks with the new version you can still use the old without uninstalling the new.I also was not aware they had added a 48-QFN to the XO2 line and even more important (to me) they've added an 84 pin QFN with 68 I/Os! That would replace an XP part I had in production that is now EOL. I can still buy them, but the price keeps going up. Not sure I'll get any more orders, but if I do I can do a respin of the board and use the XO2 device.

Nah, this is minor. if you'd had PC boards fabbed for a part that didn't exist, that would make one's face red.
