2017.3 IP Flows - Synthesis fails on Video Mixer IP in Block Design; "Synthesis target needs to be generated before calling compile_c."

Description

In Vivado 2017.3 I am seeing the following error on the Vivado Mixer IP.

The error appears when synthesizing the IP core when using either OOC generation mode, or as part of the complete design.

ERROR: [Vivado 12-3761] C:/Project_1/ Project_1.srcs/sources_1/bd/design_1/ip/design_1_v_mix_0_0/design_1_v_mix_0_0.xci: Synthesis target needs to be generated before calling compile_c.

Resetting and regenerating the output products does not resolve the issue. 

The design worked successfully in Vivado 2017.2.

Solution

A problem was found in Vivado 2017.3 where not all files of Hierarchical IP (HIP) are being generated when there is a hardware evaluation license for the IP in use.

During generation, the files are considered delivered but will not be found by Vivado.

When using a Full license, all of the files are delivered correctly.

A fix is targeted for the Vivado 2017.4 release.

A tactical patch has been created to correct this behavior for the 2017.3 release. 

With the patch applied, the files will be generated correctly for Vivado 2017.3 using the hardware evaluation license of the Video Mixer IP.

METHOD 1:

  1. Navigate to the $XILINX_VIVADO/patches directory (create this directory if it does not exist)
  2. Extract the contents of the ".zip" archive to a directory starting with the name AR70182
    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. Create a separate directory for the patched files
  2. Extract the contents of the ".zip" archive to the desired patch directory location
  3. Set the MYVIVADO environment variable to point to the Vivado directory under this patch directory
    For example:
    set MYVIVADO=C:\MYVIVADO\vivado-patch-AR70182\vivado\
  4. Run Vivado software tools from the original install location.
