HELP FOR MEMGEN

Usage: memgen <filename> [-vo] [-b]

OPTIONS:
-------
   -v       Create a VIEWlogic(tm) schematic symbol.
   -o       Create an OrCAD(tm) schematic symbol.
   -b       Compress address and data signals into busses.
            (Makes a smaller schematic symbol)

The MEMGEN program reads in the definition of the memory from an ASCII text
file with a '.mem' extension. If MEMGEN is invoked and the specified file
does not yet exist, then MEMGEN will prompt for the WIDTH and DEPTH of the
memory.  A '.mem' file will automatically be created for the design.


PARAMETERS:

file_name        -- Input Memory File Name (extension is '.mem')
                  This parameter takes a character string value.
                  must be ".mem" and is automatically added if not specified.
                  
type             -- Type of memory.
                  This parameter takes a character string value.
                  The valid values are 'RAM'. 'ROM', 'SYNC_RAM', 'DP_RAM'.
                  
parttype         -- 'parttype=<name>' target LCA device
                  This parameter takes a character string value.
                  The default value is "4005pg156".
                  If specified, this part will define the PART record in the
                  output XNF file.
                  
memory_depth     -- 'memory_depth=<n>' the depth of the memory.
                  Takes an integer value between 2 and 256, inclusive.
                  
                  
word_width       -- 'word_width=<n>' the width of each memory word.
                  Takes an integer value between 1 and 32, inclusive.
                  
                  
v                -- '-v' automatically generates a VIEWlogic(tm) symbol.
                  This parameter takes a boolean value {TRUE,FALSE}
                  The default value is FALSE.
                  
                  
b                -- '-b' symbol generator will use bus inputs.
                  This parameter takes a boolean value {TRUE,FALSE}
                  The default value is FALSE.
                  
                  
o                -- '-o' automatically generates an OrCAD(tm) symbol.
                  This parameter takes a boolean value {TRUE,FALSE}
                  The default value is FALSE.
                  
                  
old_library      -- '-old_library' XNF file will be made in the old style.
                  This parameter takes a boolean value {TRUE,FALSE}
                  The default value is FALSE.
                  
                  
output_directory -- 'output_directory=<name>' directory name for data.
                  This parameter takes a character string value.
                  The default value is "".
                  
                  
helpall          -- Show all help information
                  You can type "-helpall" to this tool to get help for ALL its
                  parameters. The default is not to show help for all
                  parameters.
