<_florent_> hi
<_florent_> it seems some small change are missing in the last mibuild commit
<_florent_> *changes
<lekernel> ah yes
<lekernel> thanks
<GitHub173> [mibuild] sbourdeauducq pushed 2 new commits to master: http://git.io/bYmrHQ
<GitHub173> mibuild/master 38e92eb Sebastien Bourdeauducq: altera_quartus: fix clock domain name

<aeris> lekernel do you have a web site presenting migen ?
ohama has quit [Remote host closed the connection]
<_florent_> about removing obj parameter in request method, what was the motivation?
<lekernel> platform info structures
<_florent_> (I don't find it very practial in fact...)
<lekernel> eg when you have differential signals and some are inverted to make PCB layout easier, you can add information in the resource about which signals were inverted
<_florent_> since we are now doing distinction between modules that have IOs and others that don't have IOs
<lekernel> also you don't need to duplicate information such as the number of NOR flash address bit - the norflash core gets that from the object it gets from mibuild
<lekernel> btw the number of lines of code of both mibuild and milkymist-ng has decreased since this change ...
<lekernel> maybe I can put the DRAM timing info into the platform description too, will have to think of that
<_florent_> but about simulation
<_florent_> suppose I want to simulate the new uart with pads parameters
<_florent_> I will have to provide a objects with all the rx, tx signals
<_florent_> the uart is maybe not a good example
<_florent_> since it only has 2 ios...
<lekernel> well yes of course, you need to provide a model for the device you are connecting to the core under test :)
<lekernel> and that model can easily provide such signals
<lekernel> you could even pass the model object as 'pads' parameter

<_florent_> yes of course
xiangfu has joined #milkymist
<_florent_> but if you get the uart core alone without it's environment and you want to simulate it you will have to look in the code where pads is used
<lekernel> that can be solved with a comment
<lekernel> the main idea of this change really is to make cores adapt to slight platform variations, such as inverted signals, number of address/data bits, etc.
<lekernel> otherwise you need to specify this info twice
<_florent_> ok I see now the advantage on this point
<_florent_> I will try to adapt my de0-nano to see if I change my mind ;)
<lekernel> cool

<lekernel> sorry, migen/mibuild is one big experimental construction site and I break stuff regularly...
<lekernel> btw have you made up your mind about icalepcs?
_florent_ has quit [Ping timeout: 245 seconds]
<_florent__> no problem for the experimental construction
<_florent__> just that I don't have enough time my designs...
<_florent__> *to adapt
<_florent__> for icaleps I don't know yet sorry
