The TIMESPEC primitive is a table that you can use to specify up to eight timing attributes (TS). TS attributes can be any length, but only 30 characters are displayed in the TIMESPEC window. The TIMESPEC table is displayed in the following figure.
For more information on "TS" timing attributes refer to the “TSidentifier” section of the “Attributes, Constraints, and Carry Logic” chapter.
