I understand the difficulty of keeping up with the latest
vendor tools and in some cases not embracing the latest toolset.
Unfortunately, I need to be at vivado 2015.2 due to the
- There is a pcie core reset issue that is resolved in vivado
- There is a transceiver reset/pll lock issue which has been
resolved in 2015.2
This is one of those cases for the reasons stated above
which we need the latest version. Without vivado 2015.2, PCIE is
unreliable during power cycles due to reset not be asserted/deasserted
correctly and the unreliable state of the transceivers based on the pll lock
I’ve tried multiple ways of upgrading the current project
above to a new vivado version without success:
- Just upgrading the IP doesn’t work
- Open a newer tool version and go through the complete process of
setting up the project fails due to a version check which is buried somewhere
Any assistance would be greatly appreciated.
