4.2i Virtex-E MAP - Guided MAP fails with "ERROR:MapLib:206 - Cannot guide LUT with output..."

描述

Keywords: ERROR:MapLib:206, guide, LUT

Urgency: Standard

General Description:
Guided MAP fails and reports the following error:

"ERROR:MapLib:206 - Cannot guide LUT with abc because two of its enclosed frags (xyz/N_455_i) have incompatible packing constraints."

解决方案

The error is due to an order-of-processing issue. The guiding of buffer/inverter pushes must occur before the guiding of LUT packing.

This problem is fixed in the latest 4.2i Service Pack, available at:
http://support.xilinx.com/support/techsup/sw_updates
The first service pack containing the fix is 4.2i Service Pack 3.
