 By default, Chipyard uses the Tethered Serial Interface (TSI) to communicate with the DUT.
 TSI protocol is an implementation of HTIF that is used to send commands to the RISC-V DUT.
 These TSI commands are simple R/W commands that are able to access the DUT's memory space.

 Assuming this example test chip is taped out and now ready to be tested, we can communicate with the chip using this serial-link.
 For example, a common test setup used at Berkeley to evaluate Chipyard-based test-chips includes an FPGA running a RISC-V soft-core that is able to speak to the DUT (over an FMC).
 This RISC-V soft-core would serve as the host of the test that will run on the DUT.
-This is done by the RISC-V soft-core running FESVR, sending TSI commands to a ``SerialAdapter`` / ``TLSerdesser`` programmed on the FPGA.
+This is done by the RISC-V soft-core running FESVR, sending TSI commands to a ``TSIToTileLink`` / ``TLSerdesser`` programmed on the FPGA.
 Once the commands are converted to serialized TileLink, then they can be sent over some medium to the DUT
 (like an FMC cable or a set of wires connecting FPGA outputs to the DUT board).
 Similar to simulation, if the chip requests offchip memory, it can then send the transaction back over the serial-link.
