Launch OpenFPGA Shell
---------------------
OpenFPGA employs a shell-like user interface, in order to integrate all the tools in a well-modularized way.
Currently, OpenFPGA shell is an unified platform to call ``vpr``, ``FPGA-Verilog``, ``FPGA-Bitstream``, ``FPGA-SDC`` and ``FPGA-SPICE``.
To launch OpenFPGA shell, users can choose two modes.
.. option:: --interactive or -i
Launch OpenFPGA in interactive mode where users type-in command by command and get runtime results
.. option:: --file or -f
Launch OpenFPGA in script mode where users write commands in scripts and FPGA will execute them
.. option:: --help or -h
