Problem Title:
1.5i Virtex MAP - ERROR:baste:263 - The LOC constraint "M19" (a PCIIOB location) ...
Problem Description:
Locate attibute on OBUFT fails Virtex PCIIOB location:
ERROR:baste:263 - The LOC constraint "M19" (a PCIIOB location) is not valid for OBUFT symbol "LO_A0_
A_OBUF" (output signal=LO_A0_A, enable signal=un270_i), which is being mapped to the following site
types:
TBUF
IOB
ERROR:xvkma - IOB PAD LO_A0_A.PAD cannot merge IO buffer LO_A0_A_OBUF, incompatible loc constraint.
ERROR:xvkma - IOB PAD LO_A0_A.PAD does not have a valid IO buffer.
Solution 1:
A work around is to place LOC properties on Pad Nets instead:
NET "net_name" LOC = "M19" ;
Where net_name is the net connecting the OPAD to the OBUFT.
