How to mirror VHDL signal in verilog Top Test bench

 What kind of problem are you having? There is pretty good documentation on nc_mirror in the NC-Verilog and NC-VHDL manuals if you just need some examples.

 A couple of clarifications:

1. I assume you meant "$nc_mirror" instead of "nc_mirror" since "nc_mirror" is a VHDL command
2. I assume "pali_digit_inst" is instantiated from the testbench and the testbench is "pali_epp_test"

 If those two assumptions are correct, then try using full pathnames for the $nc_mirror command:

•  $nc_mirror("pali_epp_test.ba8p_ready", "pali_epp_test.pali_digit_inst:pali_inst:HS_P_TESTSITE_C:ba8p:hc:hssprtready", "");

Here is the help message for your error in case it might provide more insight:

% nchelp ncelab cuvmur
ncelab/cuvmur =
        An instance of a unit could not be resolved in the libraries,
        where unit is defined in Verilog to be either a module,
        macromodule, primitive, interface or program block or a config.
        In VHDL a unit would be either an entity or a configuration.
        It is also possible that a 5.X configuration view could not be
        resolved in the libraries.
        The error could arise because the Verilog/VHDL unit or the
        5.X configuration view being instantiated in the Verilog
        module needs to be built. A rebuild is needed if a new
        version of the software was installed after the last build.
        Another reason for the problem could be an incorrect or missing
        library name, in which case it could be resolved by supplying
        the correct library name.

Venkat,

The problem in your case is that the path specified in your nc_mirror is not correct. You need to get the correct path.

The most likely cause seems to be that the vhdl top path starts with a ":" So instead of the top level entity/architecture, you replace it with ":"

Moreover, there are a few easy ways to find out the correct path with the help of tool:

a) Open the Simvision design browser (ncsim -gui or irun -gui) and drill down to the signal and then see its correct path from Right click menu "Describe" option. You can get the correct pathname which is printed in the console window.

b) On the ncsim tcl prompt (ncsim -tcl or irun -tcl), confirm the path by doing "describe <objectname>" to confirm the path.

c) Use the tcl find command to find the path name of object.

I hope it helps.
