Description

Solution

The NGC files are in ASCII, non-readable format and as a result cannot be compared directly for verification purposes. 

However, the NGC files can be compared in the following ways:

1. Convert the NGC file to a simulation model .v|.vhd file and then compare the Verilog/VHDL simulation models.

    The simulation model can be generated in the following ways.

• Run "Generate Post-Synthesis Simulation Model" in the GUI.
• Run the below "netgen" command in the Tcl Console in the GUI or in a command line prompt:

netgen -w -sim -ofmt vhdl|verilog <name>.ngc <name>_synthesis.vhd |<name>_synthesis.v

2. Convert from NGC to EDIF and compare the EDIF files. 

    To generate the EDIF file:

• Run the below "ngc2edif" command in the Tcl Console in the GUI or in a command line prompt:
  

ngc2edif -w <name>.ngc <name>.edif
