Serial RapidIO v5.6 - ERROR:MapLib:979 - LUT5 symbol "srio_icon_gen.i_srio_icon/U0/U_ICON/U_TDO........

描述

While implementing Serial Rapid IO v5.6 (Gen 1) core in ISE Design Suite, the following error messages are reported during the map stage:

ERROR:MapLib:979 - LUT5 symbol
"srio_icon_gen.i_srio_icon/U0/U_ICON/U_TDO_MUX/U_CS_MUX/I4.U_MUX16/Mmux_O11"
(output
signal=srio_icon_gen.i_srio_icon/U0/U_ICON/U_TDO_MUX/U_CS_MUX/I4.U_MUX16/Mmux
_O1) has input signal "srio_icon_gen.i_srio_icon/CONTROL0<3>" which will be
trimmed. See Section 5 of the Map Report File for details about why the input
signal will become undriven.

解决方案

To resolve this issue, please follow the steps below:

1. Right-click on "Synthesis - XST" in the Processes box,
2. Click on Process Properties
3. Change Property display level to "Advanced"
4. Uncheck the box, "Read Cores"

The issue hereis that the cores are getting wrapped into the synthesis level, when they should be getting pulled in at the NGDBUILD level. Pulling in too early prevents the ChipScope component from getting integrated properly.
