When I try to run implementation from PlanAhead software, I receive the following error:
ERROR: [HD-Project 3] Cannot launch run 'impl_1' :
ERROR:HACSCoregenInvoker:Could not locate coregen IP repository in ISE
installation. Please source the settings script included with your ISE
installation before executing the Xilinx Core Generator. ERROR:
[HD-Project 3] Cannot launch run 'impl_1' : Failed to implement
Why is this happening? I do not have any cores in my design.
This is a known issue with PlanAhead software, where it tries to launch the CORE Generator tool and is unable to do so.
This has been fixed in the 11.3 version of PlanAhead, and the software will not try to run CORE Generator when there are no cores in the design.
To work around the issue, please upgrade to the latest version of PlanAhead.
