Options for NetGen Simulation Flow
This section describes the supported NetGen command line options for timing
simulation.
• -aka (Write Also-Known-As Names as Comments)
• -bd (Block RAM Data File)
• -bx (Block RAM Init Files Directory)
• -dir (Directory Name)
• -fn (Control Flattening a Netlist)
• -gp (Bring Out Global Reset Net as Port)
• -insert_pp_buffers (Insert Path Pulse Buffers)
• -intstyle (Integration Style)
• -mhf (Multiple Hierarchical Files)
• -ofmt (Output Format)
• -pcf (PCF File)
• -s (Speed)
• -sim (Generate Simulation Netlist)
• -tb (Generate Testbench Template File)
• -ti (Top Instance Name)
• -tp (Bring Out Global 3-State Net as Port)
• -w (Overwrite Existing Files)
-aka (Write Also-Known-As Names as Comments)
This option includes original user-defined identifiers as comments in the netlist. This
option is useful if user-defined identifiers are changed because of name legalization
processes in NetGen.
Syntax
-aka
-bd (Block RAM Data File)
This option specifies the path and file name of the file used to populate the Block RAM
instances specified in the .bmm file. Data2MEM can determine the ADDRESS_BLOCK in
which to place the data from address and data information in the .elf (from EDK) or
.mem file. You can include more than one instance of -bd.
Optionally, you can specify tag tagname, in which case only the address spaces with
the same name in the .bmm file are used for translation, and data outside of the tagname
address spaces are ignored.
Syntax
-bd filename[.elf|.mem] [tag tagname]
Note When using this option, you must also use -bx (Block RAM Init Files Directory) to
specify the directory into which the Block RAM Initialization files will be written.
-bx (Block RAM Init Files Directory)
This option specifies the directory into which the Block RAM Initialization files will
be written.
