| lekernel | new slowtan6 bug: 800x600 on both channels fucks up all PLLs, including the system clock one | 20:34 |
| kristianpaul | urgh | 20:53 |
| kristianpaul | how come? | 20:53 |
| lekernel | because no spartan6 feature works correctly, ever | 21:00 |
| wpwrak | makes you wonder how the others fpgas are ... | 21:06 |
| lekernel | I had hopes for Tabula, but it turns out their software crashes way before reading the first byte of a HDL source file | 21:08 |
| wpwrak | do you think the spartan thing is just a synthesis problem, or hardware ? | 21:09 |
| lekernel | it could be because I'm not using the GCLK pins to drive the PLLs... | 21:10 |
| lekernel | but it looks hardware. works fine until a certain pixel clock frequency, then everything breaks down (including serial output) | 21:10 |
| lekernel | also works if only one channel is active | 21:11 |
| wpwrak | hmm. could it be power ? | 21:13 |
| lekernel | mh | 21:16 |
| lekernel | for some reason it doesn't happen in bios | 21:16 |
| lekernel | the PLLs lock and everything looks normal there | 21:16 |
| kristianpaul | perhaps you dont wanna do it the xilinx way (hardware thing) ? | 21:20 |
| kristianpaul | how are you driving the PLLs instead? ahh you using exp connector ;) isnt? | 21:21 |
| lekernel | yes | 21:21 |
| kristianpaul | ahh | 21:22 |
| kristianpaul | that could explain part of it, | 21:22 |
| kristianpaul | why not use glck from memcard? | 21:22 |
| kristianpaul | just to give it a chance | 21:23 |
| kristianpaul | play safe :) | 21:23 |

| davidc__ | lekernel: the PLLs are sourced from logic lines? | 21:57 |
| lekernel | yes | 21:59 |
| lekernel | davidc__, it goes through the general interconnect | 22:01 |
| davidc__ | Ah, yeah, Xilinx FPGAs really don't like when you do that | 22:03 |
| davidc__ | lekernel: if you can; try hand-wiring a *CLK capable input to the clock signal | 22:04 |
| davidc__ | and see if that fixes it | 22:04 |
| lekernel | I don't really understand why they don't like this | 22:06 |
| lekernel | is it because of jitter? internal crosstalk? | 22:06 |
| lekernel | duty cycle distortion? | 22:06 |
| davidc__ | lekernel: Probably a combination of all of the above + black voodoo magic | 22:07 |
| lekernel | I don't believe in black voodoo magic :) | 22:10 |
| davidc__ | lekernel: the occasional sacrifice is needed to get timing closure | 22:16 |
| lekernel | swearing seems to work too | 22:16 |
| lekernel | at least mine does | 22:16 |
| lekernel | this is kinda frustrating, the picture with only 1 channel really looks clean in 800x600 now ... | 22:19 |
| lekernel | maybe I should just wait for the mixxeo boards | 22:20 |
