Synopsys VCS Warning for `define redefined

Question

Is it possible to generate a warning or error in Synopsys VCS compiler if a `define macro is redefined?

 `define DATWIDTH_SZ  `DAT_SZ
 `define DATWIDTH_SZ  512

Answer 1

It works for me:

$ cat tb.v
`define DATWIDTH_SZ  `DAT_SZ
`define DATWIDTH_SZ  512

module tb;
endmodule

$ vcs tb.v
