| DMI DPI module for OpenOCD remote_bitbang driver |
| ================================================ |
| |
| This DPI module provides a "virtual" JTAG connection between a simulated chip and [OpenOCD](http://openocd.org/). |
| It makes use of the `remote_bitbang` JTAG driver shipped with OpenOCD, which forwards JTAG requests over TCP to a remote server. |
| The `dmidpi` module is instantiated in the hardware simulation to receive the JTAG requests from OpenOCD and drive DMI pins directly. |
| |
| Note that this module replaces the JTAG Debug Transport Module ("DTM") inside the debug system. |

| The `remote_bitbang` protocol is documented in the OpenOCD source tree at |
| `doc/manual/jtag/drivers/remote_bitbang.txt`, or online at |
