Looks like digikey unlisted all LIFCL-40 parts, doesn't even show up in search now.
<omnitechnomancer>
LIFCL-40?

ZirconiumX: if the offer is still open I would like to see how your chess monstrosity does on Anlogic
<sensille>
what's the deal with anlogic? are they especially cheap?
<sensille>
hm, discontinued on lcsc
<omnitechnomancer>
sensille: They are somewhat cheap AFAIK, though I think you have to go to extra effort to buy them outside of china now, I care mostly because I have a 15USD devbaord with one on it and would like this to be more useful with open source toolchain
<omnitechnomancer>
Oh also many of them have in package SDRAM
<sensille>
and a $15 devboard is big enough to host the chess solver?
<omnitechnomancer>
its got ~20K LUTs
<omnitechnomancer>
the largest figure quoted atleast for the move generator was 10k so should fit, I mostly want to see what size it gets
<omnitechnomancer>
Since it has a weird hybrid LUT4/LUT5 architecture
<omnitechnomancer>
to clarify I care about anlogic because I got a cheap board with one and wish to improve the open tooling ecosystem
<daveshah>
tnt: semiconductorstore are now listing production silicon, albeit without stock yet
<swetland>
digikey seems to no longer have them listed
<daveshah>
Yup they've killed off the ESs
<swetland>
(ah I see tnt observed that upthread)
<daveshah>
I hope that means production parts aren't far away
<daveshah>
On the plus side, it means I got free shipping despite not meeting the treshold
<daveshah>
because the part I backordered was cancelled
<swetland>
they were a bit spendy (but yeah not out of line with other parts)
<daveshah>
It is still a bit silly that 40k CrossLink NX is about the same as 85k ECP5
<swetland>
I've always found the near- or complete lack of pricebreaks on fpgas through regular distributors to be kinda obnoxious
<daveshah>
Yeah, I was at a company a few years ago that even asked for a quote for 1000 Zynqs and it still came out almost no different to single quantity (this was in the UK)
<daveshah>
For the smaller FPGAs seems to be the people buying 100ks that get the good deals
<swetland>
you *can* get significant breaks, if you're big enough, and ordering enough, and dealing with a direct rep (based on my experience back at Google), but small-to-medium shops, good luck getting the time of day
<azonenberg>
from what i hear you can get much better prices if you know the right guy in china
<azonenberg>
and i mean legit fpgas, not random sketchy pulls
<azonenberg>
but you have to know the *right* guy
<azonenberg>
Like, xc7z020s for low tens of USD
<azonenberg>
not $125 like digikey wants for them :p
<azonenberg>
Speaking of which, if anybody wants some xc7z020-1clg484c pulls, i have a few i'm scrapping soon from old client boards getting recycled
<swetland>
the quantity quotes we got were in that neighborhood
<azonenberg>
i'm keeping one to decap but letting the other silicon go in the trash seems like a waste
<azonenberg>
you'll have to reball but they'd be properly removed from working boards, old solder cleaned off, and de-fluxed
<azonenberg>
i'll have somewhere around 3 pieces available
<azonenberg>
i dont use zynqs in my personal projects, and if i did i'd buy new because i wouldnt want to risk an expensive board on a pulled chip
<TD-Linux>
whoa I used a xc7z020 for a previous project and had no idea the chips were that expensive D:
<azonenberg>
TD-Linux: you mean at work or something where somebody else paid?
<TD-Linux>
worse, at school where I only needed devkits
<azonenberg>
ah ok
<TD-Linux>
the devkit was $300 iirc
<azonenberg>
yeah the high volume price is much less
<azonenberg>
but the chips are $$$ in low volume
<azonenberg>
its like this with all fpgas, 3-10x markup in low volume vs mass prod
<azonenberg>
do you really think amazon pays $50k for an xcvu9p on their f1 instances? i think not
<azonenberg>
maybe $5k
<azonenberg>
Even that might be inflated... digikey msrp is $50k but the devkit for the same chip is $8k ish
<azonenberg>
so $5k for the bare chip might even be too high
<daveshah>
Pretty sure there were bitcoin miners with that chip around the $3k mark
<TD-Linux>
they must Have Their Reasons, I suppose, but it's pretty crazy compared to non-FPGA arm SoCs
<azonenberg>
TD-Linux: you realize the arm is like probably 5% of the die right?
<azonenberg>
its basically a slightly enlarged xc7a75t (i think ~85k cell capacity?) bolted onto an arm soc
<TD-Linux>
IIRC it was 1/8 the die
<azonenberg>
where did you get that number?
<azonenberg>
the vivado floorplan isnt necessarily super accurate
<TD-Linux>
the chunk of fpga cut out in the floorplan
<TD-Linux>
ok
<azonenberg>
When i decap one we'll know, fpga and arm look very different :p

yeah an A9 isn't all that big
<daveshah>
Particularly given the original Zynqs don't even have a GPU
<daveshah>
I wouldn't be surprised if the L2 was a decent chunk of the PS size
<swetland>
yeah 1 or 2 A9s, L2, and 256KB sram. the other peripherals are all dinky things
