NGDBuild - "ERROR:bascp:94 - Invalid UCF/NCF file entry value "" detected on line 4, offset 64..."

説明

When Constraints Editor writes out a UCF file based on the EDIF file with parenthesis as bus notation, the following error might show up in NGDBuild: 

 

bascp:94 - Invalid UCF/NCF file entry value "" detected on line 4 

(which is the line that this TIMEGRP appears). 

 

The following is an example of the constraint from the Constraints Editor: 

 

TIMEGRP "test" = FFS( "rac_num(0)" "rac_num(1)" "rac_num(2)" );

ソリューション

This is an issue with NGDBuild.  

 

There are two work-arounds: 

 

- Use wildcard character (*): 

TIMEGRP "test" = FFS( "rac_num*" ); 

 

- Use the following syntax, replacing the close parenthesis with ?: 

 

TIMEGRP "test" = FFS("rac_num(0?" "rac_num(1?" "rac_num(2?" ); 

 

This problem will be fixed in a future release.  

 

 

If the bus notation is an angle bracket (<>), there is no problem in NGDBuild with or without the double quotes. The contraint from the Constraints Editor will work fine.
