このChiselコードは問題なく動作します:
chiselMainTest(Array[String]("--backend", "c", "--genHarness"), () => Module( new Cache(nways = 16, nsets = 32) )){c => new CacheTests(c)}
ただし、これは小さなバリエーションですが、実行時エラーが発生します。
val cache_inst = new Cache(nways = 16, nsets = 32)
chiselMainTest(Array[String]("--backend", "c", "--genHarness"), () => Module(cache_inst)){c => new CacheTests(c)}
