Thefollowing error occursin NGDBuild when I attempt to synthesize EtherCAT IP Core:
"ERROR:NgdBuild:604 - logical block <instance name> with type <component> could not be resolved. A pin name misspelling can cause this, a missing edif or ngc file, or the misspelling of a type name. Symbol <name> is not supported in target <device>."
How do I fix the problem?
This issue is caused by an XST bug in 11.4.
To fix this issue, download the following patch:
Extract the attached ZIP file to the $XILINX folder.
Example : WIN : C:\Xilinx\11.1\ISE\
Linux : $XILINX/data/
Run XST againand the implementation tools.
This issue is scheduled to befixed in ISE 12.1.
