content: First of all, a well deserved "thank you" to danadak and obiwanjacobi for luring me in the PSoC world.It's really great fun and I might even end up learning Verilog.That said, I've found what I consider a serious bug in the LUT editor of PSoC Creator 4.0.If you change the sort order using the top innheaders, the outnrows will be correctly rearranged.That's really useful to compose a large LUT.BUT! If you close the window with OK with a sort order other then default, when you open the editor againthe output values will retain the order they had when the window was closed, but the input signals will be back to the default order.The obvious workaround to reorder everything to default before closing is not really doable: the sort used is not stable, and rows will switch position more or less randomly, so the natural order is not easy to reconstruct.First opening of the window:Flip a bit onout1:Reverse sort onin1:So far, so good: everything as expected.Close the LUT editor window and reopen it.This is what you get:Not really helpful. Especially on my 5in x 4out LUT.I have separately mailed Cypress customer support about the issue, but I thought of making this known, as it might affect your work/hobby and cause a lot of hair pulling...

content: A small update, from the support case I opened:QuoteA workaround is also suggested, but it does not work in general as the used sort is not stable.

content: Hi @newbrain,Usually Cypress fix this kind of bugs using Service Packs, by any chance they told you if a Service Pack is planned for Creator 4 to be released soon?
