A longer than usual runtime has been reported during the call to pre_route.tcl. The message PICXO-106 shows a very high number of seconds to complete pre_route.tcl.
In 2016.1, the tool crashes with an "out of memory" message.
Why is the runtime increased? How can I speed it up?
The runtime is increased because the license server is called every time route_design is called.
pre_route.tcl calls route_design a number of times and so the runtime can increase significantly if the license server checkout is slow.
To work around the problem in versions prior to 2016.1:
Note: Two messages relating to PICXO-210 appear. The first one states that the Tcl file should be used post placement but this is incorrect. It must be used pre-placement or post opt_design.
To work around the problem in Vivado 2016.1:
The next release, v2.5, will resolve the runtime and crash issue.
