The PDI_SPI_SEL, PDI_SPI_DI and MII_RX_CLK0/1/2 signals are used as clock inputs for a few registers at low speed. ISE/EDK/PlanAhead: CLOCK_DEDICATED_ROUTE=FALSE constraint required You should now have a file named rdiArgs.bat Copy the new rdiArgs.bat file to C:Xilinx14. Solution Either set Global optimization to OFF or add the CLOCK_DEDICATED_ROUTE=FALSE constraint. Open C:Xilinx14.7ISEDSPlanAheadbin and rename rdiArgs.bat to Download the attached zip file Extract it. This issue is reported to Xilinx and present at least until ISE 14.5. This issue occurs especially when the MAP option “Global optimization” is different from OFF. This results in an error message suggesting to add a CLOCK_DEDICATED_ROUTE=FALSE constraint to the clocks. Under certain circumstances, the tools insert additional BUFGs into the clock signals to the EtherCAT IP Core (CLK25, CLK100), or the BUFGs are not placed at optimal sites. ISE/EDK/PlanAhead: Additional BUFG inserted This issue is approved by Xilinx, but there will not be any future version of ISE. The crash was caused by libSecurity_FNP.dll. Now, Xilinx should be just as stable as it. Now do this to this new directory: rename 'libPortability.dll' to '', and rename 'libPortabilityNOSH.dll' to 'libPortability.dll'. After installing both ISE 14.7 and Vivado 2014.1 on a Microsoft Windows 7 64 bit operating system, a crash occurred while synthesizing the EtherCAT IP Core using ISE 14.7. Now, copy the file libPortabilityNOSH.dll from 'C:Xilinx14.7ISEDSISElibnt64' into 'C:Xilinx14.7ISEDScommonlibnt64'.
