# Filename    : ila_1.sh
# Simulator   : Synopsys Verilog Compiler Simulator
# Description : Simulation script for compiling, elaborating and verifying the project source files.
#               The script will automatically create the design libraries sub-directories in the run
#               directory, add the library logical mappings in the simulator setup file, create default
#               'do/prj' file, execute compilation, elaboration and simulation steps.

# Prerequisite:- To compile and run simulation, you must compile the Xilinx simulation libraries using the
# 'compile_simlib' TCL command. For more information about this command, run 'compile_simlib -help' in the
# Vivado Tcl Shell. Once the libraries have been compiled successfully, specify the -lib_map_path switch
# that points to these libraries and rerun export_simulation. For more information about this switch please
# type 'export_simulation -help' in the Tcl shell.
#
# You can also point to the simulation libraries by either replacing the <SPECIFY_COMPILED_LIB_PATH> in this
# script with the compiled library directory path or specify this path with the '-lib_map_path' switch when
# executing this script. Please type 'ila_1.sh -help' for more information.
