Command Reference2.  FPGA Express Shell Commands      script_chip



_N_A_M_E
          script_chip    Write a synthesis script


SYNTAX
          string script_chip [-dir _p_a_t_h__n_a_m_e]
                 [-dc] [-fe]

         string    _p_a_t_h__n_a_m_e


ARGUMENTS
          -dir _p_a_t_h__n_a_m_e Specify the output directory for the
                         script file.


          -dc            Write a Design Compiler shell script
                         template.


          -fe            Write an FPGA Express shell script
                         template.


DESCRIPTION
          This command creates a file that contains fe_shell or
          Design Compiler commands based on the current chip.
          The current chip may be either pre-optimized or
          optimized.  The file can be used as a template for more
          complex synthesis scripts.  The name of the script file
          is based the name of the current chip with the .fes or
          .dcsh extension.  The default behavior is to create an
          fe_shell script.

          When generating Design Compiler scripts, script_chip
          will read the timing constraints on the current chip
          and write equivalent Design Compiler constraint
          commands.  The clock information that is automatically
          determined by FPGA Express is translated to equivalent
          Design Compiler commands.  The commands to read and
          analyze the source files are also translated.  Comments
          are provided in the Design Compiler script in areas
          where the user must supply additional information.

          When generating fe_shell scripts, commands needed to
          regenerate the current chip are written.  Currently,
          not all constraints are supported.

EXAMPLES
          This example creates a Design Compiler script
          AM2910.dcsh in the current working directory.
               fe_shell > current_chip AM2910

               fe_shell > script_chip -dc


          This example creates an fe_shell script AM2910-
          Optimized.fes in the the directory named `out_dir'.
               fe_shell > current_chip AM2910-Optimized
               fe_shell > script_chip -dir out_dir
