calibre自带v2lvs命令使用指南

做为现今流行的 深亚微米集成电路物理验证工具,calibre 有其强大的功能,其 v2lvs命令能够方便的把verilog格式网表转为spice格式网表,对于IC后端的工程师来说是非常有用,且有必要掌握的。命令: v2lvs

可用参数:[-l verilog_lib_file] [-lsp spice_library_file] [-lsr spice_library_file] [-s spice_library_file] [-s0 groundnet] [-s1 powernet] [-sk] [-p prefix] [-w warning_level] [-a array_delimiters] [-c char1[char2]] [-u unnamed_pin_prefix] [-t svdb_dir] [-addpin pin_name] [-b] [-n] [-i] [-e] [-h] [-cb][-ictrace]

参数介绍:·
·-v verilog_design_file
Specifies the filename of the input Verilog structural netlist.
· -o output_spice_file
Specifies where to place the output LVS SPICE netlist. Default is standard out.
· -l verilog_lib_file
Specifies the location of the Verilog primitive library file. It is not translated.
· -lsp spice_library_file
Specifies SPICE library file name using pin mode. The SPICE file is parsed for interface configurations. Pins with pin select ([ ]) annotation are kept as individual pins using escaped identifiers.
· -lsr spice_library_file
Specifies SPICE library file name using range mode. The SPICE file is parsed for interface configurations. Pins with pin select ([ ]) annotation are assembled into Verilog ranges.
· -s spice_library_file
Specifies that the -o output file have a .INCLUDE statement placed at the beginning that points to the SPICE library file.
· -s0 groundnet
Specifies the default net name for mapping to pin connections with a value of zero (0). Outputs the specified names in place of Verilog supply0 nets and generates .GLOBAL declarations in the output netlist.
· -s1 powernet
Specifies the default net name for mapping to pin connections with a value of one (1). Outputs the specified names in place of Verilog supply1 nets and generates .GLOBAL declarations in the output netlist.
· -sk
Specifies that Verilog supply0 and supply1 nets are not connected to the global
power and ground nets.
· -p prefix
Adds prefix to Verilog gate level primitive cells.
· -w warning_level
Controls the amount of warning message output. Possible level choices are:
0 Selects to output no warning messages.
1 Selects to output warning messages for skipped blocks and modules only.
2 Selects to output level 1 and calls to undeclared modules and pin arrays
with widths wider than ports. This is the default.
3 Selects to output level 2 and called port array mismatches and
unsupported compiler directives.
4 Selects output level 3 plus all ignored constructs.
· -a array_delimiters
Changes the array delimiter characters. The default is [ ].
· -c char1[char2]
Sets the substitution characters for escaped identifier characters illegal in
SPICE. char1 replaces $, comma, (, ), and =. char2 replaces /. No space is
needed between the two user-supplied arguments.

· -u unnamed_pin_prefix
Specifies a prefix to add to unnamed pin connections in module instantiations.
· -t svdb_dir
Adds source netlist pin direction information to the SVDB. This is used in
Calibre xRC.
· -addpin pin_name

大多数时候是把 .V的网表转为CDL或SP的时才用, GDS的DRC和LVS也会用到
