* IO Ring
* JTAG Boundary Scan
-JTAG
+JTAG also contains a Wishbone Master for direct access to Memory
+and also a DMI Interface for controlling the core. In simulations
+a JTAG client was implemented both in nmigen HDL as well as
+verilator. The exact same openocd scripts and direct
+JTAG connectivity using jtagremote can then be used on:
+
+* nmigen HDL simulations
+* verilator simulations
+* FPGA
+* ls180 ASIC
