这段代码的问题在于,在ST2结构体初始化时,使用了花括号而不是方括号。此外,在ST4结构体中,st2_arr数组的声明中缺少花括号。以下是修改后的代码,应该可以通过vcs编译:
```verilog
module test;
typedef struct packed {
logic [9:-1][2:0] a; //REQ-EXT-10001, REQ-EXT-10004
} ST1;
typedef struct {
ST1 st1;
logic [2:0] b;
} ST2;
typedef struct {
logic [31:0] c;
} ST3;
typedef struct {
ST3 st3;
ST2 st2_arr[3:0];
} ST4;
initial begin
ST2 st2;
ST2 st2_1 = {3'b101, {{10'b110}}, {{20'b10101010101010}},{{30'b1}}};
ST2 st2_2 = {3'b010, {{10'b101}}, {{20'b01010101010101}},{{30'b0}}};
st2 = {3'b1, {{10'b110}}, {{10'b1010101010}}, {{10'b1010101010}}, {{10'b1010101010}}, {{10'b1}}};
$display("%p",st2);
$display("st2_1:%p", st2_1);
$display("st2_2:%p", st2_2);
ST4 st4 = '{0, '{'{10'b0}}, '{'{10'b0}}, '{'{10'b0}}, '{'{10'b0}}};
$display("st4:%p", st4);
end
endmodule
```
