azonenberg changed the topic of ##openfpga to: Open source tools for FPGAs, CPLDs, etc. Silicon RE, bitfile RE, synthesis, place-and-route, and JTAG are all on topic. Channel logs: https://libera.irclog.whitequark.org/~h~openfpga
<gurki>
not neccesarily for foss tooling which still really struggles with it, but its heavily used in the commercial stuff
<gurki>
if you want a glance at "which language is being used" foss might not be the best metric for eda things
<schaeg>
Thank you for your input. I basically wanna get a feel for whether we should take VHDL-A as input language or go more of a mnigen route and make our own HDL.
<gurki>
what dont you like about veriloga?
<gurki>
also be carefull with hdl and vhdl-a and verilog-a, neither are typically synthesizable
<gurki>
its a bit of a hack, really.
<gurki>
i personally would probably use spice combined with spice or verilog-a subcircuits
<gurki>
you could go mixed signal, embedding spice in plain verilog but i dont ssssssssssssssssssenefit
<gurki>
see much benefit. wtf keyboard sorry.
<schaeg>
I don't like verilog. (personal preference). The target audience are scientist/engineers who want to run programs which involve solving differential equations which get mapped to a configuration of switch matrices of other things where then electrons solve a similarish ODE on the analog computer.
<gurki>
youre not gonna have fun with anything mixed signal in vhdl im afraid. the strong-typedness really bits you in the a**
<gurki>
bites*
<gurki>
the latter is why i actually prefer it for digital, but ive moved over to the verilog team since i do a lot of mixed signal design
<schaeg>
We do not having any user programmeable digital logic though. Just a user programmable micro controller. So we would synthesize a VHDL-A/Verilog-A/OurOwnHDL program to run strictly in the analog domain.
<gurki>
is this really plain opamp or do you use stuff like memristors?
<gurki>
there are quite a bunch of synthesis efforts for the latter going on
<schaeg>
Plain Opamp.
<gurki>
which process if i may ask?
<gurki>
node*
<schaeg>
Or that is all we publically talked about atleast.
<schaeg>
You may ask, but i am not sure i can answer.
* schaeg
checks. No can't answer.
<gurki>
wouldve given me a pretty good idea where youre headed, but i will obv accept if you arent allowed to share details :)

> The modern analog computer Analog Paradigm Model-1, uses integrated circuit technol- ogy which is comparable to the 1970s digital integration level. Nevertheless it achieves competitive results in com- putational power and energy consumption compared to a mature cutting-edge digital processor architecture which has been developed by one of the largest companies in the world. We also computed a problem-dependent effective FLOP/sec
<schaeg>
value for the analog computer. For the key performance measure for energy-efficient computing, namely FLOP-per- Joule, the analog computer again obtains remarkable result
<gurki>
i dont have time to read a full paper right now, but ill have a glance at it later
<schaeg>
So it would be safe to assume our next gen product is better 1970s level of digital integration.
<schaeg>
I don't think you get much more out of it then this for your process node question.
<Flea86>
schaeg: I once read somewhere that analog computation was not yet obsolete and that the last chapter had yet to be written.
