Fatal when run a case in VSIM

Hi, I write a simple case test.S.After the compilation,I want to simulate it in VSIM. But it gave me a hint :

Fatal: "/home/lh/rocket-chip/src/main/resources/vsrc/TestDriver.v", 147: TestDriver: at time 1000000500 ps
$finish called from file "/home/lh/rocket-chip/src/main/resources/vsrc/TestDriver.v", line 147.
$finish at simulation time            100000050

I find the cause is timeout in TestDriver.v

my case test.S is following:

       .section .text.init
        .align  6
        .weak stvec_handler
        .weak mtvec_handler
        .globl _start
_start: 
li a1, 0xAAAAAAAA
li a0, 0xAAAAAAAA
add a2, a1, a0
	j pass
pass:
	fence
	li gp, 1
	li a7, 93
	li a0, 0
	ecall
RVTEST_CODE_END
    .data
RVTEST_DATA_BEGIN
EXTRA_DATA


TEST_DATA

RVTEST_DATA_END

The last 5 are macros in riscv_test.h. And there is another macro called RVTEST_CODE_BEGIN, when I use it , it will succeed; but when it not be used ,the fatal will appear:
Fatal: "/home/lh/rocket-chip/src/main/resources/vsrc/TestDriver.v", 147: TestDriver: at time 1000000500 ps $finish called from file "/home/lh/rocket-chip/src/main/resources/vsrc/TestDriver.v", line 147. $finish at simulation time 100000050

So what should i do ?
My environment is Ubuntu18.04 ,

Start by reading src/main/resources/vsrc/TestDriver.v around line 147 and compare the test with and without RVTEST_CODE_BEGIN in riscv_test.h. Reproduce the VSIM command using the supplied test.S and determine why the run reaches the timeout; done means explaining the difference and identifying the required test setup or a verified fix.
