Description
Keywords: timegroup, grouping, missed, question mark, asterisk, TNM
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.
