Folks, are the gowin SRAM based FPGAs supported?
<lofty>
singham: #yosys-apicula
<lofty>
singham: SOFA leverages the OpenFPGA framework to use Yosys through their own scripts, but it's not directly supported upstream because they haven't contributed anything upstream
<lofty>
Also, with the full disclosure that I used to work for the University of Utah who develop OpenFPGA (but not on OpenFPGA itself)
<lofty>
OpenFPGA is very definitely one of the FPGA frameworks of all time
<singham>
What is yosys-apicula?
<singham>
lofty: Don't worry about the full disclosure thing. Internet is way more untrustworthy. Today, absolutely nothing can be verified on internet without meeting the person in real life.
<singham>
I mean so called beautiful technology AI has overriden trust in internet.
<lofty>
singham: it's a tradition for FPGA reverse engineering projects to have codenames; gives them a bit of identity
<lofty>
Project Apicula is the project to reverse engineer Gowin FPGAs, and its IRC channel is #yosys-apicula
<singham>
Interesting
<singham>
I find it a bit astonishing that FLASH based FPGAs were solved before SRAM ones
<whitequark>
(solved?)
<singham>
Meaning the way to code them was found through reverse engineering
<whitequark>
as far as I know, SRAM ones came first
<whitequark>
well, unless you count GreenPAK4, which isn't really flash based (it uses an OTP ROM)
<singham>
Just the littlebees are supported right?
<singham>
They're FLASH based.
<whitequark>
oh, you mean by Gowin specifically?
<singham>
Yes
<whitequark>
from a RE perspective, in my experience, SRAM based and Flash based devices don't make a lot of difference
<whitequark>
I've RE'd a family of CPLDs which has both Flash and SRAM devices
<whitequark>
the bitstreams are nearly identical
<singham>
Yes, but still, I can't buy a board, and then find it is not supported by symbiflow
<singham>
That would be bad.

gotta go. Will see you folks later. Thanks lofty and whitequark
