2013.1 Vivado Implementation - opt_design crashes during the sweep phase while trying to remove an unused IDELAYCTRL instance


opt_design can crash during the sweep phase while attempting to remove an unused IDELAYCTRL instance.


This bug has been fixed in the Vivado 2013.3 release.

In 2013.1 and 2013.2 the crash can be avoided in the following ways:

  • Apply a dont_touch property to the unused IDELAYCTRL
  • Remove the unused IDELAYCTRL from the source
  • Skip the sweep phase of opt_design
