Foundation Schematic - "PPR ERROR 9028" encountered when using COMPMC8 macro in a 5200 design
Description
Keywords: PPR, Foundation, 9028
Urgency: Standard
General Description: The following error may occur during the Place and Route of an XC5200 design:
*** PPR: ERROR 9028: The following block of the set $I2/hset does not represent a legal block configuration for this device. Check the logic shown below against the requirements of RLOC constraints, BLKNM parameters, and X and P signal parameters.
Symbol Name = $I2/$1I3 Type = CY_MUX RLOC = R1C1.LC0 Symbol Name = $I2/$1I1965 Type = CY_MUX RLOC = R1C1.LC0 ....
Note that in the line "RLOC = R1C1.LC0", the RLOC attributes refer to column 1 instead of column 0. This is an error in the Foundation XC5200 library.

In order to use the COMPMC8 in an XC5200 design, you must make a local copy of the macro and edit it to correct the RLOC attributes.
Please see (Xilinx Solution 1657) for instructions on copying a Xilinx library component.
Open up the macro schematic and modify all the RLOC attributes for the 'LT' logic to use column 0 'C0'.
