fitzsim` is now known as fitzsim
<awygle> AFAICT academic tools like VPR or T-VPACK are completely unusable on real FPGAs in their current forms
<awygle> (this comment brought to you by awygle finally finding the T-VPACK paper)
<rqou> the dissertation talk i attended today about hardware RE is a bit... unfortunate
<rqou> it's currently about an order of magnitude slower than our ugly hack
<rqou> but the approach is completely different
<rqou> arguably their approach is "nicer"
<awygle> rqou: so what's their approach?
<rqou> essentially the difference is described as matching on the structure of the netlist vs matching on the behavior of the netlist
<rqou> one of their approaches is to take the circuit that you want to match and do some initial probing of it with some k-hot vectors
<rqou> this makes a graph of what outputs are activated by what inputs
<rqou> and then it's possible to search for this as a subgraph of activations in the actual "haystack" netlist
<rqou> btw azonenberg we need better benchmark circuits
<awygle> Ah. I think I've seen papers talking about that approach or something similar
<awygle> There is a collection of "standard" fpga benchmark circuits that is referenced in lots of papers but which I have not been able to actually find
<rqou> btw does somebody have a broken htc vive setup?
<rqou> can you pull the ice40 bitstreams?

<balrog> rqou: you're sure it can't be found in their firmware updates?
<balrog> aiui the ice40 doesn't do much
<balrog> just timing computations
<rqou> i'm not sure
<rqou> but it's still useful to test against our silicon RE tools

<whitequark> cyrozap: hehehe
<cr1901_modern> A bunch of old anime also have a number of shots which have monitors filled with source code... I wonder if there are any full programs that OCR could capture (or one could transcribe).
<rqou> whitequark: offtopic: why do you keep using conda when it seems to have tons of dumb problems?

<pie_> im horribly stuck in a youtube autoplay bubble
<pie_> ive been listening to the same tracks for days
<awygle> long as they're good ones I guess
<pie_> ive gotten pretty tired of them
<pie_> i put something on then two hours later notice im in the terminal loop again
<awygle> Holy cow I just read "if you have a UNIX(TM) machine on the Arpanet..." this paper is clearly too old
<awygle> "We are prepared to send you a 9-track tape in TAR format"
<awygle> Oh hey a reference to OpenFPGA.org
<jn__> pie_: if you need something else to watch, i recommend this: https://www.youtube.com/watch?v=378S5Owi-BI
<jn__> pie_: it's a pretty good intro to OS/360 and operating systems in general
<pie_> awygle, you mean org.openfpga, is that on usenet
<awygle> It's a Consortium
<awygle> There's also an openfpga Inc in Ohio
<awygle> Apparently the former became the latter in 2006
