EOF (end of file) within comment [2.3(IEEE)

hi,
I was executing the top module of an sv environment and this error showed up

`include "counterinterface.sv"
`include "counterdut.v"
`include "countertestbench.sv"

module top();
bit clk;

always #2 clk = ~clk;

counterintf intf (clk);
counter dut (.d(intf.d),
             .clk(intf.clk),
             .reset(intf.reset),
             .load(intf.load),
             .up_down(intf.up_down),
             .qd(intf.qd));
testbench tb (intf);

endmodule

The error goes like this **ncvlog: *E,NOEFIC (countertop.sv,19|9): EOF (end of file) within comment [2.3(IEEE)].
irun: 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).

Can u please help me to find the reason behind this error?

In reply to jwl1806:

Somewhere you have a ‘/’ without a matching '/’. Since you are `including a lot of files, it is probably in one of those.

Thanks for the help. It was a /* *\ mismatch.
