Hello,
I am trying to synthesize an opensource risc-v core on the ZC706 board. The implementation step terminated after "Attempting to get a license for feature 'Implementation' and/or device 'xc7z045'", shown by the log below. I think I have all the licenses installed. If not, Vivado would have complained even before starting the implementation phase.

The original project which compiled successfully was using the Nexys Video board. I am porting it to the ZC706 board. I modified the top level module and the constraint file accordingly. My changes are mainly disabling the unavailable peripherals and using the differential clock on the board.
The "hs_err_pid27787.log" log is attached. I cannot understand anything from this file. Therefore, any help is greatly appreciated!
