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...
解决方案
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.
