hi, I have to use special character & in the module name and I have named the file name same as module name (added space at the end of the module name). I wasn't able to compile, looks like vcs is not accepting space in the file name : ------------------ module \&abc_123 ; integer \&$$abc ; initial begin \&$$abc =20; $display("&$$abc =%d",\&$$abc ); #10 $finish; end endmodule ------------- Did I miss anything? Any help Please.
