10.1 NGDBuild/Constraint - "ERROR:XdmHelpers:xxx - processing property '' on signal '' ...encountered bad token"

Description

When I run the "Translate" step in NGDBuild, an error similar to the following occurs: 

 

"ERROR:XdmHelpers:683 - Processing property "TNM_NET=hierarchy1/busname(15)_repl1" on signal "hierarchy1/busname(15)_repl1": Encountered bad token "_repl1" while parsing TNM_NET value "hierarchy1/busname(15)_repl1"." 

 

My constraints file contains the following, which seems to cause the problem: 

 

NET "hierarchy1/busname(15)_repl1" TNM_NET = "hierarchy1/busname(15)_repl1";

Solution

Although NGDBuild is reporting the error on the token "_repl1," it is actually unable to parse the "/" and "()" characters in the time name. To avoid these errors, change the constraint so that it conforms to the following format: 

 

NET "hierarchy/busname(15)_repl1" TNM_NET = "busname_15_repl1"; 

 

Be sure to change the use of the TNM elsewhere in your constraints as well, so that the same format is followed.
