2016.x Vivado - Implementation log file (.vdi) in the reports view gets overwritten if Generate Bitstream is rerun


In the Vivado GUI, the Reports window lists "Vivado Implementation Log" for each implementation step:

  • place_design
  • route_design
  • write_bitstream

When any of these reports are selected, Vivado opens the .vdi file in the implementation run directory.

This works in general but, if I re-run the write_bitstream step (with some other setting for example), the .vdi file contains only the log of the last write_bitstream call.

The logs of the previous steps are lost. As a result, when I double click on the Place Design "Vivado Implementation Log", I get a report that does not contain any place log.


To work around this issue do one of the following:

  • Open the Design Runs window, right click on the implementation run (for example, impl_1) and select Display Log.
  • Navigate to the implementation run directory (my_proj/my_proj.runs/impl_1) and open the runme.log file.
