<Wanda[cis]> by the way, if anyone knows how to obtain obscure ancient FPGA/CPLD toolchains, there's quite a few of them I'd be interested in
<Wanda[cis]> right now I'm interested in ORCA Foundry, which may or may not be a modified XACT

<Wanda[cis]> (also I'm still interested in ancient Philips toolchains for XPLA2 and older Coolrunners)
<Wanda[cis]> (also in XACT versions supporting XC8100, XC6200, or XC4025 which is somehow missing from my copy)

<q3k[cis]> this fucks
<q3k[cis]> used to be available at ftp://orca.fast.net/orca/iftw/foundry935.zip
<q3k[cis]> nothing more frustrating than the realization that something just used to be on an FTP server 20 years ago which no-one bothered to back up
<q3k[cis]> i'll send an email to pldworld.com (also a site that hasn't changed since 1999)
<jn> ooh, apparently Lattice bought Agere (ex-Lucent) ORCA FPGA in 2002 (http://www.aufzu.de/semi/lucent.html)
<Wanda[cis]> oh yes
<Wanda[cis]> almost the entire Lattice portfolio is derived from AT&T Orca
<Wanda[cis]> via Agere and Lucent
<jn> wow
<Wanda[cis]> like. ECP/XP/MachXO are even called Orca 5 in some Diamond data files
<Wanda[cis]> Orca, btw, is directly derived from XC3000, which AT&T was second-sourcing as ATT3000
<Wanda[cis]> which makes ECP* a direct descendant of Xilinx tech
<jn> i didn't expect so much intertwined history
<q3k[cis]> Wanda: we need a jebani_kurwa_vendorzy_fpga.dot file
<Wanda[cis]> q3k: I have a WIP
<Wanda[cis]> there are two Lattice FPGA lines that are *not* derived from AT&T tech, btw
<Wanda[cis]> one is ice40, which is SiliconBlue tech they acquired
<jn> and ice65 based on ice40, or something else entirely?
<Wanda[cis]> the other is an obscure thing called XPGA or ispXPGA which is, I think, a Lattice FPGA design made before the Lucent FPGA tech acquisition
<jn> hmm
<Wanda[cis]> it uses a completely different toolchain than everything else (not based on NeoCAD) AFAICT
<Wanda[cis]> jn: the other way around, ice40 is derived from ice65
<jn> ah, interesting
<Wanda[cis]> ice65 was a short-lived series which got quickly replaced with ice40
<Wanda[cis]> the 65 and 40 refer to 65nm and 40nm btw
<jn> makes sense
<Wanda[cis]> and then there's the Gowin devices
<Wanda[cis]> which are very closely derived from ECP3
<Wanda[cis]> in... you know, the chinese way
<sdomi> q3k[cis]: there also was a foundry93.zip and some other files in that directory. i wish you've seen my post before you poured time into it, i spent half of last night searching for it everywhere
<jn> hm, https://picture.iczhiku.com/resource/eetop/wHKEeyoDdLaewmXM.pdf (old lattice document in chinese) mentions orca.fast.net, which unfortunately isn't in the web archive either
<jn> (orca.fast.net/orca/fpsc_design_kits/for_isplever2.0)
<sdomi> (my post, and what i arrived at yesterday, being this https://donotsta.re/notice/Aochb7X4gSrloZDL3g )
<q3k[cis]> welp
<Wanda[cis]> (and then there's Anlogic, which also has the distinctive Lattice device smell, but it's not nearly as much of a blatant copy as Gowin)
