Problem Title:
Foundation 1.4, MAP: ERROR:basnu:93 - logical block <instance number> of type "OBUF" is
unexpanded... when OMUX2 is used in XNF netlist
Problem Description:
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.
Solution 1:
Exporting the design to XNF file format is not supported for
XC4000XL and XC4000EX devices. Instead, use the default EDIF
(.EDN) flow.
