Problem Title:
**Obsolete**Foundation Schematic: PPR ERROR 9028 when using COMPMC8 macro in 5200 design
Problem Description:
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.
Solution 1:
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.
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'.
Solution 2:
For the correct schematics, refer to Page 3-48 in On Line Libraries Supplement Guide.
