General Description: 

An error similar to the following occurs in NGDBuild when I run a command line script to implement the Xilinx PCI-X LogiCORE: 

"ERROR:NgdBuild:393 - Could not find INST (S)'XPCI_WRAP/XPCI_CORE/XPCI_FRAMET' in design 'PCIX_TOP'.  

INST entry is 'INST "XPCI_WRAP/XPCI_CORE/XPCI_FRAMET" IOB = TRUE;"

ソリューション

These errors are generated when NGDBuild cannot find the netlist for the PCI-X core. The netlist for the PCI core is called  

"pcix_core.ngo". 

This file is located in the following directory: 

<LOGICORE_PCI-X_INSTALL_DIR>/<hdl>/src/xpci 

The XPCI directory must be sourced by the NGDBuild command line. 

Command Line Example: 

ngdbuild -sd ../../src/xpci  

-sd ../synthesis  

-uc ../../src/ucf/2v1000fg456_64s.ucf  

../synthesis/pcix_top 

The best implementation method is described in the implementation guide, which is located in the <LOGICORE_PCI-X_INSTALL_DIR>/docs directory.

The "pcix_core.ngo" file represents the PCI-X LogiCORE. NGDBuild takes in this file and merges it with your netlist. The resulting file is a single NGD file that contains both the user application and PCI-X LogiCORE.
