Nand2Tetris-project5, Error: No such built-in chip used: RAM16K

Question

当我通过 computerAdd.tst 脚本测试 computer.hdl 时，我的硬件模拟器显示错误：No such built-in chip used: RAM16K，但我已经将 RAM16K chip.hdl 复制到这样的文件夹中。有谁知道为什么吗？

Computer.hdl:

CHIP Computer {

    IN reset;

    PARTS:
    // Put your code here:
    ROM32K(address=pc, out=instruction);
    CPU(inM=inM, instruction=instruction, reset=reset, outM=outM, writeM=writeM, addressM=addressM, pc=pc);
    Memory(in=outM, load=writeM, address=addressM, out=inM);
}

computerAdd.tst:

load Computer.hdl,
output-file ComputerAdd.out,

// Load a program written in the Hack machine language.

repeat 6 {
    tick, tock, output;
}

// Second run, to check that the PC was reset correctly.
set reset 0,

}
