AR# 25042

説明

When EDK uses DCM in a Virtex-4 system, the following warning occurs at simulation. 

"# ** Warning: Attribute Syntax Warning The attribute FACTORY_JF on DCM_ADV instance * is set to 1100000010000000. 

 # Legal Values for this attribute is F0F0 hex 

 # Time: 0 ps Iteration: 0 Instance: /system/dcm_0/dcm_0/using_dcm_adv/dcm_adv_inst"

ソリューション

You can safely ignore this warning. EDK sets the DCM attribute "FACTORY_JF" to "C080"; however, BitGen sets the attribute to the correct value "F0F0." 

This problem has been fixed in the latest EDK 9.1i Service Pack, available at:
