Instead, Chipyard uses TSI commands to bringup the core (which normally results in a faster simulation). +TSI simulations use the SimSerial interface to directly write the test binary into memory, while the DTM +executes a small loop of code to write the test binary byte-wise into memory. However, if you want to use JTAG, you must do the following steps to setup a DTM enabled system. Creating a DTM/JTAG Config
