@Catherine: I am assuming there is no way to mix verilog with amaranth with glasgow?
15:24
<
whitequark[cis] >
you can still use platform.add_file
15:24
<
whitequark[cis] >
ah, hm, one sec
15:26
<
whitequark[cis] >
yep, you should be able to do that
15:29
<
nemanjan00[m] >
Hmm, great 😄 Opens up a lot of options, with ADC, DAC and DSP cores 😄
15:30
<
whitequark[cis] >
though none of these would ever be upstream
15:31
<
nemanjan00[m] >
Well, I guess that does not stop me from using it myself 😄
15:31
<
whitequark[cis] >
yep
15:32
<
nemanjan00[m] >
Maybe at some point someone will implement some DSP cores in amaranth
15:32
<
whitequark[cis] >
i mean you can just... do that?
15:32
<
whitequark[cis] >
DSP isn't magic
15:32
<
whitequark[cis] >
(also what the hell is an ADC or DAC core?)
15:33
<
nemanjan00[m] >
No, I meant I could create addon with ADC and DAC chip and do stuff like filtering, fft and stuff like that on glasgow 😄
15:33
<
nemanjan00[m] >
Maybe simple osciloscope addon
15:33
<
whitequark[cis] >
I really doubt the iCE40 we use has enough power for an FFT
15:34
<
nemanjan00[m] >
I really do not know how many gates it has, but maybe for slow signals? Small window...
15:34
<
whitequark[cis] >
it doesn't even have multipliers
15:34
<
whitequark[cis] >
and it has less than 8000 4-LUTs
15:35
<
whitequark[cis] >
you could maybe do some extremely simple first-order filtering
15:35
<
nemanjan00[m] >
Ok, I guess I overestimated it
15:35
<
whitequark[cis] >
anyway, given how cheap aliexpress oscilloscopes are, it is not worth it economically to develop any such addon that is viable
15:36
<
whitequark[cis] >
maybe in speed, but not in convenience
15:36
<
nemanjan00[m] >
Any easy way to see how many LUTs applet is?
15:37

AMARANTH_verbose=1 glasgow build --rev C0 ...
15:37
<
nemanjan00[m] >
Thanks
15:39
<
nemanjan00[m] >
I have a full sized scope (MSO5000), I was going more for realtime operation of peripherals from trace (custom triggering), but I guess that is not practical with that small of an FPGA
15:40
<
whitequark[cis] >
you don't actually need either filtering or FFT for that, necessarily
15:41
<
nemanjan00[m] >
Oh, that was another idea, more radio focused 😄 Custom filters, for ham radio use or maybe audio processing in general

OpenOCD folks suggest implementing FTDI MPSSE protocol on the Glasgow side as remote_bitbang is not that fast
18:27
<

But it looks like remote_bitbang SWD should get merged soon

<davidrysk[m]> "OpenOCD folks suggest implementi..." <- this was actually the original plan for Glasgow as a project
23:24
<
whitequark[cis] >
however, as the project evolved, it became clear that it should not be emulating other USB devices, so it would not do that
