<larsc> the downside of this method for the fifo counter is that there is quite a bit of combinatorial dealy for the gray counter output
<larsc> it's still the bottleneck in my design
<larsc> if you do the comparison in binary you can pipeline the conversion to gray

<ysionneau> oh, I didn't know you could make an (sigma delta) ADC in a FPGA by using LVDS IO ports
<larsc> because you can use the lvds input as a comperator?
<ysionneau> yes I guess
<ysionneau> sounds logical since differential IOs are basically comparing the two lines
<ysionneau> pretty cool
<ysionneau> there is an I€€€ paper as well about that
<ysionneau> but you need to pay like $$$30
<larsc> yea, saw that as well

<ysionneau> hum, writting {A,B,C,D} in fpga RAM and reading back into {B,A,C,D} is not a fantastic idea :)
<ysionneau> now lm32 unittests pass again
<ysionneau> very useful those unit tests that mwalle did for the mmu :)
<ysionneau> and very well written

<ysionneau> weird indianness :p
<wpwrak> military-grade encryption. (enigma)
<ysionneau> so well encrypter it could not boot anything, not even unit tests :p
<ysionneau> encrypted*
<lekernel> xilinx does something like that for their PLL control data
<lekernel> no idea why
<lekernel> but bits forming e.g. the multiplier and divider values are spread all over the place

<wpwrak> (test results) sounds like a great victory. useful for my monthly statistics :) how many boards were made in this run ?
<lekernel> 10
<wpwrak> so the next run will be the big one ?

<lekernel> hmm, maybe
<lekernel> the designers insisted I move the micro-USB connector, though that should be relatively risk-free
<wpwrak> do creotech also do the SMT ? or are they just taking care of testing and maybe logistics ?
<wpwrak> ("do the SMT") as in "have a line"
<lekernel> yes, they do the SMT
<wpwrak> great. it's nice to have the ability to check PCBs right at the end of the line.

<wpwrak> the only drawback i see is that they're really hard to reach, in case you have to visit them ;-)
<larsc> Now I'm getting timing errors on my reset signals...
<wpwrak> that's what you get for playing god and messing with the fundamental constants of the universe
<larsc> no, thats what I get for using the reset signal from the wrong clock domain...
<larsc> but my dma controller is finally able to run at 295 Mhz on the datapath

<wpwrak> oh, i had found some company with that/a similar name in lodygowice, which would be really remote. didn't look very high-tech either, though apparently doing some engineering. can't find it anymore :-(
<wpwrak> let's repeat this when he's back ..
<davidc__> wpwrak: its probably creotech.pl . They build stuff for cern, so probably a reputable mfg
<wpwrak> yes, they look right. the other one looked more like two guys (at most) and a soldering iron. if they're actually in electronic :)
<wpwrak> can't figure out what sort of url i used
<wpwrak> hah, found it ! :) http://coretech.pl/
<wpwrak> that's what i get for not using copy & paste
<wpwrak> and thanks, google chromium for watching (and recording) every step i take ;-)
<wpwrak> so yes, they look like as if they'd do electronics. but not quite like the sort of guys who have an SMT line in the backyard.
<ysionneau> creotech .. coretech ... it's almost just a typo between one and the other
<wpwrak> i guess either gets the occasional strange mail :)
