The generator tile +plugs into the existing SoC generator as what looks like a CPU. However, +instead of running programs, the tile generates fixed memory requests out to +the L2. There are both cached and uncached generators. The cached generator +has an intervening L1 cache, the uncached generator sends TileLink requests +directly to the L2. + +Assertions are set to fail if the wrong data comes back or if a request times +out waiting for the response.
