tnt | _florent_: so turns out that the workaround I used to get sys_clk above doesn't work ... | 06:29 |
---|---|---|
tnt | it results in multiple `wire` in the generated verilog, each of them with the don_touch attribute set ... forcing vivado to create multiple clock networks, each skewed with each other. | 06:29 |
tnt | mmmm ... maybe I was a little quick to jump to the conclusion that this was the issue. yet TBD | 07:00 |
tnt | Nope nevermind, it was the issue. | 07:47 |

_florent_ | tnt: I imagine you are trying to apply a constraint internally in a submodule/peripherals of the SoC. What you could also do is add a "add_timing_constraint" method to your module and call it from the SoC | 14:09 |
_florent_ | tnt: similar to this: https://github.com/enjoy-digital/litex/blob/master/litex/soc/cores/dna.py#L43-L45 | 14:09 |

tnt | _florent_: yeah, I ended up just passing the sys_clk signal to the constructor directly. | 20:37 |
tnt | I'm having trouble bringing the JESD link up for some reason. It was working a couple month back, haven't tried it since and ... not sure what I'm screwing up now. | 20:38 |
