Description

I created a constraint similar to the following and I am receiving errors: 

PIN "and*" TPSYNC = "and_star_tpsync" 

 

My error(s) look similar to the following: 

 

"ERROR:ConstraintSystem:58 - Constraint <PIN "and*" TPSYNC = "and_star_tpsync"> 

[bufpll_div1.ucf(23)]: PIN "and*" does not match any design objects."

Solution

The * and ? will work for part of a component name, or for part of a PIN name, but not for both at the same time. 

 

Generally, a PIN is referred to with the following syntax: 

<COMP>.<PIN> 

 

In the above example, 'and*' would not be able to find any PINs. To work around this issue, use 'and*.*'. This change allows the Constraints System to search both component names and PIN names.  

 

Following is the required modifications performed on the above example: 

PIN "and*.*" TPSYNC = "and_star_tpsync" 

 

This issue is scheduled to be fixed in the next major release of software.
