5.x PPR - Timing constraints ignored when invoked from the command line

Description

A user choosing to run the xmake flow by running the programs individually from the command line or via a batch file may see that PPR is ignoring all timing constraints written in the .cst file, even if that file is explicitly specified.

解决方案

Timing constraints are written into the .xtf file by XNFPREP. Therefore, the "cstfile=" option must be specified for command-line execution of XNFPREP in order for .cst file timing constraints to be read.
