ppi2040:[Error] The instance '$1I1/O' of component type 'OBUFT' is not supported or...
Description
When compiling an XC7000 design with the 5.2.0 EPLD software tools (workstation only), the following error may be encountered:
xemake 5.2.0 ppi2040:[Error] The instance '$1I1/O' of component type 'OBUFT' is not supported or the netlist was not generated with the XC7000 library.
This is caused by errors in the xnf7000 library for version 5.2.0.
解决方案
The problem has been fixed in XACT v5.2.1.
Either upgrade to XACT v5.2.1, or replace the xnf7000 directory with the files from the XACT v5.2.1 release.
