3.1i XFLOW - ERROR:Trace:19 - Unable to access design file after Control-C (Ctrl-C) is used to interrupt PAR


Keywords: XFLOW, XFlow, Xflow, PAR, TRCE, control-c, ctrl-c, interrupt, ERROR, 19, post_par_trce, error code 1

Urgency: Standard

General Description:
If a Control-C (Ctrl-C) is used to interrupt XFLOW while it is running PAR, a menu of
choices is presented.

Selecting choice 3, "Exit program immediately," results in PAR terminating
immediately. However, XFLOWdoes not terminate and attempts to run
POST_PAR_TRCE, resulting in the following errors:

ERROR:Trace:19 - Unable to access design file: <design>.ncd
ERROR: Xflow - Program post_par_trce returned error code 1. Aborting flow execution...


This error occurs because PAR does not pass the proper exit code to
XFLOW on termination, resulting in the continuation of XFLOW's
processing. Although inconvenient, this issue causes no harm
to the design files.

This problem is fixed in the latest 3.1i Service Pack available at: The first
service pack containing the fix is 3.1i Service Pack 4.
