 cache parameters. For example, by changing L1I, NWays to 4, you will get
 a 32KB 4-way set-associative L1 instruction cache rather than a 16KB 2-way
 set-associative L1 instruction cache.

 To build the emulator with `DefaultConfigRBB` configuration we use the command:
 
     rocket-chip$ cd emulator
-    emulator$ CONFIG=freechips.rocketchip.system.DefaultConfigRBB make
+    emulator$ CONFIG=DefaultConfigRBB make
 
 We can also build a debug version capable of generating VCD waveforms using the command:
 
-    emulator$ CONFIG=freechips.rocketchip.system.DefaultConfigRBB make debug
+    emulator$ CONFIG=DefaultConfigRBB make debug
 
 By default the emulator is generated under the name `emulator-freechips.rocketchip.system-DefaultConfigRBB` in the first case and `emulator-freechips.rocketchip.system-DefaultConfigRBB-debug` in the second.
