xobsAh, the chipdb files are linked in, and each one is huge.02:20
cr1901_modernoh right that sounds about right02:20

cr1901_modernit's a tradeoff of having a flat db vs a db for each chip. Or something02:20
mithroxobs: 52.8 MB02:20
mithroI think the chipdb could be as little at ~10-15k02:22

rohitksingh_workmithro: Mimas A7 has FT2232H, so it is possible to stream mpeg frames over it at (but it's bulk endpoint, so no guaranteed bandwidth). Other option is to create a carrier/module for it.04:59
rohitksingh_workbtw Mimas A7 has 6 locations where pmods can be directly connected, but you cannot use all 6 probably at the same time...max 4 can use at the same time05:01

ewenmithro: re VCD and GtkWave, https://pypi.org/project/pyvcd/ and particularly https://pyvcd.readthedocs.io/en/latest/vcd.gtkw.html look interesting.  The latter seems to help create *.gtkw save files for GtkWave that load the VCD file.07:30

ewen:-)07:59
ewenmithro: The thing I'm trying to figure out is how to get the signal names from the simulation to give to the vcd.gtkw to write into the file list to load...08:00
ewen(looks like some of them are self.FOO attributes on the dut, and others seem to magically appear elsewhere).08:00
ewenmithro: I'm suspecting the easiest way is going to be to parse the VCD file back off the disk to find out what is inside it, and then write the gtkw file using those.  Because at present the best view of the signals I can see is *inside* the Simulator class.  And since we're using run_simulator() we never see that Simulator class.08:06
ewenHmm, run_simulation() is trivial.  So we could perhaps replace that, and hang onto the Simulation longer.08:09

The moment I closed all the windows, litex-buildenv just popped up.

bunniebtw, anybody got an ICE40 reference design using migen that also uses a PLL? nextpnr is ignoring the sys_clk constraint, claiming the net doesn't exist (but I can see it in the verilog), and then nextpnr errors out saying clock constraints are incomplete...17:44
*** sc00bz has left #timvideos18:07
daveshahbunnie: unfortunately sometimes a different name for the net can be picked18:08
daveshahRun without any clock constraints first and see what it is called in the timing report18:09
daveshahThere is a heuristic to try and pick the highest level name, or the alphabetically first one if multiple exist at the same level18:09
bunniethanks! I'll give that a try.18:19
*** sc00bz has joined #timvideos18:22
bunnieso, i think i removed the constraints by commenting out the top_pre_pack.py constraints, but I still got an error         self.platform.add_period_constraint(self.crg.sys_clk, 1e9/clk_freq)18:33
bunnieoops that's not it18:33
bunnieWarning: timing analysis failed due to presence of combinatorial loops, incomplete specification of timing ports, etc.18:34
bunniethat one18:34
bunniehowever, i can get it to compile with --force as the argument.18:34
bunniewhen i remove the PLL and just use a SB_GB buffer buffering the clock signal to one of the exact same name as it would have without the PLL, things also seem to work (without --force)18:35
bunnieit also looks like it's somehow picking 12MHz as a clock constraint out of thin air when i don't have any apparently defined?18:35
bunniebasically, the error i get starts with a very long list of ports and the top looks like this:18:37
bunnieInfo: Annotating ports with timing budgets for target frequency 12.00 MHz18:37
bunnieInfo:    remaining fanin includes GLOBAL_BUFFER_OUTPUT (net crg_sys_clk)18:37
bunnieInfo:         driver = SB_GB.GLOBAL_BUFFER_OUTPUT18:37
bunnieInfo:         user: $auto$simplemap.cc:420:simplemap_dff$10434_DFFLC.CLK18:37
bunnieInfo:         user: $auto$simplemap.cc:420:simplemap_dff$11078_DFFLC.CLK18:37
bunnieand then ends with the note about "Warning: timing analysis failed due to presence of combinatorial loops, incomplete specifications of timing ports, etc."18:37
bunnieAny tips on how I might start to debug a problem like this? or should I just keep on using --force and ignore the error.18:38
daveshahThe 12MHz constraint is a default (some internal algorithms need a frequency to work) for clocks without a constraint, set using the `--freq` command line argument18:49
daveshahThe most useful thing to do is put a netlist somewhere where I can look at it. It seems like this is something broken around the PLL18:50

bunniesure, here's a copy of my gateware directory: http://bunniefoo.com/bunnie/gateware/19:13
tpbTitle: Index of /bunnie/gateware (at bunniefoo.com)19:13
daveshahCoincidentally I think I just found the problem19:13
daveshahyep19:13
bunnieoh cool19:13
daveshahyou have a global buffer connected to PLLOUTGLOBAL19:13
daveshahthis is not incorrect, but also not a useful pattern (hence hit an edge case in nextpnr)19:14
bunniei see. PLLOUTGLOBAL is able to drive the global clock network directly?19:14
daveshahmight as well remove that global buffer, all it's doing is wasting a global and adding some skew to the pll output19:14
daveshahthe whole point of PLLOUTGLOBAL is it is a global network19:14
bunnieok cool.19:16
bunnieyep that fixed it19:16
bunniesorry, I come from xilinx land and typically a PLL output isn't useful without a BUFG behind it. thanks!19:16
daveshahObviously it shouldn't create that error either, but the global outputs of the PLL weren't being marked internally as clock output type ports, so timing analysis treated them wrongly19:20
daveshahBut I think, separately, a warning for this pattern would be useful (as globals are a scarce resource on the ice40)19:21
bunniedoes nextpnr also support the other PLL blocks like SB_PLL40_2F_PAD and what not?19:23
bunniealso, while I have you, even though I've constrained the clock I still get this : Info: Annotating ports with timing budgets for target frequency 12.00 MHz19:25
bunnieit correctly computes slack histograms from the clock of interest that is not at 12 MHz. Should I just ignore this or does this mean maybe I've missed some paths that should be constrained?19:25
felix_nats`: haven't gotten around to try to make litex work with zynq, but this might be worth a look: https://github.com/cjbe/artiq-zynq https://github.com/cjbe/artiq/commits/zynq_hacks https://github.com/peteut/migen-axi19:26

daveshahThat 12MHz thing is a bad message, it should be removed19:28
*** ewen has joined #timvideos19:29
daveshahAt the end it will print all the clocks (and cross clock pairs if they exist) that it finds19:29
bunnieok thanks! I really appreciate the tips.19:29
bunnieOne thing that would be neat, but might be hard, would be to propagate clock constraints automatically through PLLs. Vivado is pretty easy that way for constraining a chip clock, you just corrcetly configure the input clock and all the derived clocks from PLLs are automatically annotated.19:31
daveshahI'm working on that19:31
daveshahWe actually do the most trivial case already, copying constraints 1:1 through global buffers19:31
bunnieoh neat. that will be nice. :) but for now, manual annotation is quite fine. I just need to figure out how to convince migen to output the name that nextpnr is picking for the clock.19:31
bunnielooks like easiest way to do it is to just put a "z" in front of any net alias that can confonud nextpnr, as it's resolving the chain alphabetically it seems. thanks! that would have taken me forever to figure out without the tip about how it picks the clock names.19:36
daveshahIt should be possible at some point to process net aliases properly in nextpnr, so it will accept any of the names19:36
daveshahYosys does tend to preserve them into the json at least19:37
