calibre 中怎么用 v2lvs 把 verilog 网表转换成 spice 网表 v2lvs -v verilog_design_file -o output_spice_file [-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] Arguments · -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
