Wasn't aware that the ECP4 even existed!
<daveshah>
it only exists in landfill
<jeanthom>
haha why
<daveshah>
perhaps a few dusty drawers of abandoned giveaway dev boards
<daveshah>
it was scrapped shortly after the first samples were given to customers
<jeanthom>
ah that's sad
<daveshah>
Lattice suddenly realised they couldn't compete with Xilinx et al. and decided to pivot towards cheap/really low end instead
<daveshah>
I have a suspicion they did some big yield optimisations between ECP4 and ECP5
<cr1901_modern>
Well that wasn't that long ago... but 3.11 is a lot more than 2.0
<daveshah>
If anyone does have an ECP4 dev board lying around (any big Lattice customers here??) I would love to buy it...
<daveshah>
At least Nexus does reintroduce a lot of the nice features from the ECP4 that the ECP5 dropped; like 8x/10x IO gearing, fabric-accessible dynamic PLL configuration, separate IO CDR blocks
<awygle>
if only it came cheaper
<daveshah>
It's hard to tell if Nexus is just super pricy or Lattice have gone for Xilinx style ludicrous single/low qty pricing - either way a shame after the ECP5
<daveshah>
It would also be nice to be able to buy it at all, availability now seems to be Feb-March 2021
<jeanthom>
mouser has some devboards in stock, but no chips :(
<cr1901_modern>
economies of scale sucks
<daveshah>
The current devboard stocks are also probably still ES silicon, and I believe that will be dropped in new Radiant versions - as well has having some totally undocumented set of bugs
<cr1901_modern>
Early Samples?
<daveshah>
engineering sample
<awygle>
i'm kind of hoping they have bad yield on all the hard IP blocks
<awygle>
and if we get a more vanilla fabric version it'll be cheaper
<awygle>
or else market-positioned lower even if not actually cheaper for them
<awygle>
that may be wishful thinking though
<daveshah>
I was hoping that with the Certus NX (removing the Mixel MIPI core) but sadly that didn't work out
<daveshah>
I reckon the Certus is the most vanilla-fabric one there will be
<daveshah>
There are two more parts planned in the near/medium future. My best guess, based on what has been hinted so far in various ways, is one iCE40 successor (small packages, low power, no SERDES/PCIe/MIPI) and one ECP5 successor (up to ~150k LUT4, SERDES and PCIe)
<cr1901_modern>
Where does MachXO5 fit into it?
<daveshah>
They'll have to get reliable flash working on their 28nm FDSOI first
<daveshah>
I doubt MachXO is moving soon, MachXO3D was only just released
<cr1901_modern>
that was also another thinly-veiled "Lattice can't count" joke :)
<daveshah>
Eh, PSION didn't like 4 either
<cr1901_modern>
4 is a superstituous number in some parts of the world
