From 216826a9e5ca17776c6d30e24ca3dcc26c6e1cc7 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 21 Apr 2017 14:12:15 +0200 Subject: [PATCH] adv7511: audio_clkgen: Disable clock source buffer insertion Depending on the configuration of the clock source type of the input clock the clocking wizard will instantiate all kinds of buffers on the input clock signal. For these particular projects there is no need to add any kind of buffer since the source is already coming from a global clock buffer. So set the configuration accordingly. Avoids the following warning: [Opt 31-32] Removing redundant IBUF since it is not being driven by a top-level port. i_system_wrapper/system_i/sys_audio_clkgen/inst/clkin1_ibufg Resolution: The tool has removed redundant IBUF. To resolve this warning, check for redundant IBUF in the input design.
