ncvlog: *W,UNBINS: Unbound instance found:

[dipakg]

Hi,

I am trying to instiate the interface inside .v file and passing that interface instance in other two separate .v files.

Following are the files and content inside files. I am using ius6.2 version to run using ncsim command.

1. my_tb.v -> inside ./project/v_files/
`include my_intf.sv
module my_tb();
my_intf my_if();

my_driver d1(my_if);

my_wrapper w1(my_if);
endmodule

2. my_driver.v -> inside ./drivers/v_files/
`include my_intf.sv
module my_driver(interface m1_if);
m1_if.getData();
drive();
endmodule

3. my_wrapper.v -> inside ./project/v_files/
`include my_intf.sv
module my_wrapper(interface m2_if)
m2_if.setData();
endmodule

4. my_intf.sv -> inside ./project/intf_files/
interface my_intf;
task setData();
task getData();
endinterface


When I run the test, it gives me following error message:

ncvlog: *W,UNBINS: Unbound instance found: my_if::my_intf in unit worklib.my_tb:module.
ncvlog: *E,UNBERR: (1) unbound instance(s).
Total errors/warnings found outside modules and primitives:
errors: 1, warnings: 3
ncverilog: *E,VLGERR: An error occurred during parsing. Review the log file for errors with the code *E and fix those identified problems to proceed. Exiting with code (status 1).
ncsc_run: *E,TBSIMF: ncverilog returned non-zero exit status
make: *** [build_simulator] Error 1

Build execution time = 0:00:04

Can anybody tell me what can be the issue? If I get the answer today, it would be a great help.

Thanks,
