OpenVera Native Testbench
ntb_options -ntb_incdir /usr/muddappa/include+/usr/vera/include
-ntb_opts no_file_by_file_pp
File by file preprocessing is done on each input file, feeding the
concatenated results to the parser. To disable this behavior, use
no_file_by_file_pp.
-ntb_opts tb_timescale=value
Specifies an overriding timescale for an OpenVera program. This
option allows you to generate different timescale values for each
OpenVera program.
Example:
-ntb_opts tb_timescale=1ns/10ps
-ntb_opts dep_check
Enables dependency analysis. Files with circular dependencies are
detected. VCS issues an error message when it cannot determine
which file to compile first.
-ntb_opts print_deps
Supplied with dep_check. Tells the compiler to output the
dependencies for the source files to standard output or to a user
specified file.
-ntb_opts use_sigprop
Compiling the OpenVera program with this option enables the signal
property access functions.
The functions supported are:
• function integer vera_is_bound()
