M1.5 Timing analysis doesn't use TPTHRU as more specific than FROM:TO

描述

FROM:THRU:TO, Constraints.

General Description: Timing analysis doesn't prioritize a FROM:THRU:TO

as more specific than FROM:TO.

解决方案

The resolution is to place a PRIORITY on the FROM:THRU:TO

Example:

TIMESPEC TS01=FROM:FFS:THRU:ABC:TO:FFS:20:PRIORITY:1;

This will cause TRCE to analyze this above all other FROM:TO

timespecs in the design.
