I use the opb_iic core in my EDK design. PlatGen generates the error below when I set the parameter C_GPO_WIDTH to 0:
'ERROR:MDT - H:\Case\Case_551217\system.mhs:42 - PARAMETER C_GPO_WIDTH has value 0 which does not fall in the range (1:8), specified in MPD"
To solve this problem, you can edit the file C:\EDK\hw\XilinxProcessorIPLib\pcores\opb_iic_v1_01_c\data\opb_iic_v2_1_0.mpd.
The incorrect line:
PARAMETER C_GPO_WIDTH = 1, DT = INTEGER, RANGE = (1:8),
The correct line is:
PARAMETER C_GPO_WIDTH = 1, DT = INTEGER, RANGE = (0:8),
This problem is not seen with v1.01.b as there is no range for this parameter.
1.00c is now deprecated, and the specification is correct in 1.00d indicating the valid range is 1 - 8.
This problem is fixed in the latest 6.3 EDK Service Pack, available at:
The first service pack containing the fix is EDK 6.3 Service Pack 2.
