OpenVera Native Testbench
For example:
x == 0;
x == 5;
Allowed values are 0, 1, and 2. The default value is 2.
If +ntb_enable_solver_trace_on_failure is specified
without an argument, the default value is 1. The default is 2, if the
option is not specified.
+ntb_exit_on_error[=value]
Causes VCS to exit when value is >0. The value can be:
- 0: continue
- 1: exit on first error (default value)
- N: exit on nth error.
When value = 0, the simulation runs to completion regardless of
the number of errors.
+ntb_load=path_name_to_libtb.so
Tells VCS which testbench shared object file libtb.so to load.
+ntb_random_seed=value
Sets the seed value used by the top level random number
generator at the start of simulation. The random(seed) system
function call overrides this setting.
Value can be any integer number.
