LogiCORE IP Defective Pixel Correction v5.00.a (Vivado 2012.1) - Why is my design containing the Defective Pixel Correction core failing with a multiple driver error when using Vivado Synthesis?

描述

Why are my outputs always driven to zero when using Vivado Synthesis?

ERROR: [Synth-442] multi-driven net

解决方案

This is a known issue in the Defective Pixel Correction core v5.00.a when generated from Vivado 2012.1 software.

This issue can be worked around by changing the project synthesis options in Vivado to XST.

  • Select the "Synthesis Settings" link on the left hand side of the Vivado GUI and choose "XST Default" from the drop-down menu.

This issue is fixed in Vivado Design Suite 2012.2.
