15:24 <nemanjan00[m]> @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]> https://www.aliexpress.com/item/1005005644784105.html you are not beating this

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 <whitequark[cis]> 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

18:09 <jwise0[m]> 👀 👀 👀 I wonder what PLD it is using

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

18:27 <davidrysk[m]> But it looks like remote_bitbang SWD should get merged soon

23:23 <whitequark[cis]> <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
