XAPP1276: PICXO v2.5 example design hangs during route_design step with memory leak issue


When the PICXO v2.5 example design is implemented in non-project mode, it hangs at the route_design step with a memory leak issue, and ultimately results in tool crash with the following message:

terminate called without an active exception
Abnormal program termination (6)

This issue is OS independent and occurs only in non-project mode. Project mode implementation works without issues.


This is a problem with the IP which is currently under investigation. To work around this issue, the following steps can be used.

After completion of the place_design step and generation of post_place.dcp, use the following commands:

  • close_project
  • open_checkpoint $dcp_dir/post_place.dcp
  • source $ip_dir/PICXO_FRACXO_0/picxo/picxo/pre_route.tcl
  • route_design
