Hi,
I've tried to regenerate a bitstream from the projet v0.94 in the Redpitaya repository, and at the timing check, the requirement were not met.
for example :
Is it normal ? do i have missed some step ?

Re: Timing requirement
Hi,
it is normal that some of the projects >0.92 do not meet timing requirements in implementation. Most of the violations are marginal, and some only occur because not all constraints are defined correctly. 2ns of negative hold slack is not marginal, but since it's on an inter-clock path, it's probably just a matter of underdefined constraints.
If you find a way to improve this situation, I'm sure the developers will be thrilled to hear about it ;O)
