Foundation 1.4, MAP: ERROR:basnu:93 - logical block <instance number> of type "OBUF" is unexpanded... when OMUX2 is used in XNF netlist
説明
Keywords: basnu:93, OMUX2, xnf, OBUF
Urgency: Standard
General Description:
In F1.4 if user uses an OMUX2 in an XC4000EX or XC4000XL schematic and exports the design to an XNF netlist, the following error will appear in the MAP stage of the implementation:
ERROR:basnu:93 - logical block <instance> of type "OBUF" is unexpanded. Errors detected in general drc.
ソリューション
Exporting the design to XNF file format is not supported for XC4000XL and XC4000EX devices. Instead, use the default EDIF (.EDN) flow.
