6.2i MAP/PAR - Timing-driven packing runs out of memory during phase 6.8

描述

Keywords: -timing, timing, driven

Timing-driven packing runs out of memory on a 2 Gb Windows machine during phase 6.8 on a design that is using only 1.1 Gb of memory early in the phase. The reported memory usage at failure is only 1.43 Gb. This problem also occurs during PAR.

NOTE: The timing-driven packing messages are displayed when the following environment variable is set:

SET XIL_MAP_TMSG=1

For general information about setting ISE environment variables, see (Xilinx Answer 11630).

This Answer Record is a good match for your issue only if the failure occurs in MAP or PAR during phase X.8, where X is any number. This particular memory issue does not occur when the same design is run on a Linux machine. This problem originally occurred with Virtex-II designs; however, now all device families are affected.
