AR# 75374

描述

In Vivado 2020.1, some designs cause a crash when the report_qor_suggestions command is run twice in the implementation flow, i.e when running report_qor_suggestions on existing suggestions in the design.

For Example:

place_design
report_qor_suggestions -of_objects [get_qor_suggestions ] -name test
phys_opt_design
report_qor_suggestions -of_objects [get_qor_suggestions ] -name test

解决方案

This issue will be resolved in the 2020.2 release of Vivado.

A tactical patch has been created to avoid the issue in Vivado 2020.1.

Below are the instructions for the attached patch file.

METHOD 1: (Vivado 2014.4 and later only)

1. Navigate to the $XILINX_VIVADO/patches directory (Linux) or C:\Xilinx\Vivado\<vivado_version>\patches (Windows) directory (create this directory if it does not exist)
2. Extract the contents of the ".zip" archive to a directory starting with the name AR75374
   Note: most extraction tools will allow you to automatically create a directory the same name as the zip file
3. Run Vivado software tools from the original install location.

METHOD 2:

1. Creating a separate directory containing patched files
2. Extract the contents of the ".zip" archive to the desired patch directory location.
3. Set the XILINX_PATH environment variable to point to this patch directory
    i.e. set XILINX_PATH=C:\XILINX_PATH\vivado-patch-AR75374\vivado\
4. Run Vivado software tools from the original install location.
