Example of Classic Timing Analyzer Tcl Script
This section has provided an overview of Tcl commands for applying
timing constraints.
For more information on the application of timing constraints using Tcl
commands, refer to the Tcl Packages and Commands chapter in the
Quartus II Scripting Reference Manual.
Once all global assignments, resource assignments, and timing
assignments have been specified, the next step in the design process is to
compile the Stratix II FPGA prototype design. The execute_flow
command is provided for this purpose and supports various arguments
affecting the compilation process. The syntax for this command is:
tcl> execute_flow \
[-analysis_and_elaboration] \
[-attempt_similar_placement] \
[-check_ios] \
[-check_netlist] \
[-compile] \
[-compile_and_simulate] \
[-early_timing_estimate] \
[-eco] [-export_database] \
[-fast_model] \
[-generate_functional_sim_netlist] \
[-import_database]
