Compile-Time Options
files for processing in OpenVera encrypted IP mode. Unlike the
-ntb_filext option, the default encrypted-mode extensions
.vrp, .vrhp are not overridden, and will always be in effect. You
can pass multiple file extensions at the same time using the plus
(+) character.
-ntb_vl
Specifies the compilation of all Verilog files, including the design,
the testbench shell file, and the top-level Verilog module.
Options for Different Versions of Verilog
+systemverilogext+ext
Specifies a file name extension for SystemVerilog source files. If
you use a different file name extension for the SystemVerilog part
of your source code, and this option, you can omit the -sverilog
option.
+verilog2001ext+ext
Specifies a file name extension for Verilog 2001 source files. If
you use a different file name extension for the Verilog 2001 part
of your source code, and this option, you can omit the +v2k option.
+verilog1995ext+ext
Specifies a file name extension for Verilog 1995 files. Using this
option allows you write Verilog 1995 code that would be invalid in
Verilog 2001 or SystemVerilog code, such as using Verilog 2001
or SystemVerilog keywords, like localparam and logic, as
names.
Note:
Do not enter all three of these options on the same command line.
