as a relative beginner - run --trace only shows "external" signals (as opposed to the VCDs that fall out of the simulator). Is that a (hard) technical limitation, or would that "just" be complicated to implement
<Wanda[cis]>
it's not a hard limitation, but each traced signal is relatively expensive and tracing everything would not be feasible
<Wanda[cis]>
we could conceivably add some way to add selected signals to the trace set
<fridtjof[m]1>
mm, i see
<Wanda[cis]>
(we have some ... pretty ambitious plan regarding adding nicer ILA support in Amaranth and Glasgow, but it's quite a bit of work and time before that happens)
<fridtjof[m]1>
i suppose i can repurpose some unused i/o to sort of debug internal signals by putting them out there
<Wanda[cis]>
oh yeah, that would work

good news: it worked
<fridtjof[m]1>
bad news: it raised even more confusion at what's going on lol
<fridtjof[m]1>
is there a way to replay external waveforms as part of a simulation?
<Wanda[cis]>
kind of, yes
<Wanda[cis]>
there's the record & replay functionality that we use for tests
<Wanda[cis]>
I'm not really familiar with that part of code though
<fridtjof[m]1>
hmm, i looked at it for a bit and it seems it just mocks the applet interface
<fridtjof[m]1>
so more or less what's going through the fifo
<mwk>
oh hm.

but I don't remember, and might do it differently today!
<tpw_rules>
are you familiar with any of the bosch testbenches and documents?
<Attie[m]>
testbench no, docs somewhat
<Attie[m]>
> not very far - correct, sadly
<tpw_rules>
ok, i might start something myself
<Attie[m]>
would be awesome to see!
<tpw_rules>
did hardware ever end up materializing?

yes I have a functional board, though iirc VCCIO (or equivalent) needed to be wired up
<Attie[m]>
... I don't recall if I ordered the wrong part, or if it's a design mistake. I suspect former, but wouldn't hurt to write it up (might be NC on designed part??)

A lot of can phys are the same except for whether they have vccio or vsplit or similar on that one pin, it's pretty annoying

yup.. but would fit one N console completely. 4GiB (well 72bit-wide intended for ECC) of DDR3 and pcie host interface.. and 41 megabits of blockRam..
