Documentation revision 1.1, thanks to Wojciech A. Koszek for many comments on it.
Also updating howto, splitint it in INSTALL, HOWTO, FAQ and synthesis_examples, so it should be more clear now what to do when and not to try too much when you don't need. Like everyone was trying to debug the simulation but didn't even test the regular simulation before. Again thanks to Wojciech A. Koszek for his view on this matter. |

Adaption to or1200_r3. It is still important to change or1200_defines.v:
-`define OR1200_BOOT_ADR 32'hf0000100 to `define OR1200_BOOT_ADR 32'h00000100 |

minsoc SoC documentation had 2 small typo corrections. Performance penalty due to addition of register addresses was a wrong assumption. On project description "is composed by" -> "consists of". Thanks to Wojciech A. Koszek.
howto, at some places the howto did not tell the path from the files being talked about. I tried to always specify the path for every commented file.
Scripts for running the simulation called bash instead of sh. For compatibility reasons sh is now used, this should affect noone. Scripts do not use bash specific commands and generally every UNIX like computer has sh. Thanks again to Wojciech A. Koszek, who adapted that to port it to FreeBSD. |

Finishing the howto for Spartan3E Starter Kit with Ethernet. Last hint, change uart baudrate to 9600 to avoid the baudrate skew problem due to truncation.
Following the howto to implement Ethernet on Spartan3E Starter Kit will work flawlessly now. |

1) Period calculations through 1/freq on testbench use now a numerator definition in order to extract nano seconds of the divisions. Previously the number 1e9 was being repeatedly typed as numerator, now FREQ_NUM_FOR_NS is used.
2) There is a possibility of enabling the GENERIC_CLOCK_DIVISION for the testbench, so that you can test the outcome of different system clock inputs and internal clock adjustments. To do so, NO_CLOCK_DIVISION definition of minsoc_bench_defines.v has to be commented out.
-This also requested the initialization of the internal registers clk_int and clock_divisor of the minsoc_clock_manager.v, this is made by the testbench in case the NO_CLOCK_DIVISION definition is NOT defined.
3) Howto part of implementing Ethernet for the Spartan3E Starter Kit has been completely described. (Chapter 7, subitem 3) |

Simulation library fpga_memory_primitives.v had an issue with its lpm_ram_dq module, which did not output its data.
The data was being output to doq instead of q, the declared output. doq was also not defined anywhere else.
Icarus Verilog did not detect this, because Verilog-2001 allows internal wires to be used without being defined. To detect this errors, one can define "`default_nettype none". After doing this, Icarus Verilog detected that error and nothing else.
doq changed to q, error corrected. |

On version 34 of the Advanced Debug System the signal debug_tdo_o from the altera_virtual_jtag has changed to debug_tdo_i.
This commit adapts minsoc_top.v accordingly. |

Updated the howto document to adapt minsoc to a new update of the Advanced Debug System.
-Compilation of adv_jtag_bridge needs a Makefile adjustment.
-Simulation and Implementation have to remove a definition on the adbg_defines.v file.
Both adjustments simply removes the new JSP (JTAG Serial Port), which has been included in the new release of the Advanced Debug System. |

minsoc_defines.v had a semicolon at the end of the two reset polarity definitions.
minsoc_top had a signal array for two different signals which was for backward compatibility. The compatible debugging module is so old that there is no reason for keeping it.
Documentation has been updated to better explain how to use the definitions files, minsoc_defines.v and or1200_defines.v. An example for Altera devices has been added too. |

Documentation update. How To: 7) Examples:
-Spartan 3E Starter Kit no Ethernet has been already tested and is known to work.
-Spartan 3E Starter Kit with Ethernet not yet.
-change of sw/support/orp.ld cannot be done by only commenting and uncommenting line, the instruction, documentation line, which said so has been removed.
-Further possibilities -> Further area optimization possibilities. |

Ethernet testbench speed penalty solved. Now Ethernet of testbench and minsoc can be enabled by only uncommenting `define ETHERNET on minsoc_defines.v.
send_mac, get_mac and uart_send tasks have been included/improved. Also a testbench, which works for both included firmwares is added. (eth and uart)
If ETHERNET is defined for the SoC, both firmwares will complete successfully. If not, the eth firmware will stall when trying to access the Ethernet module. |

Updating spartan3e_starter_kit.ucf so that it does not deliver errors on mapping. Moreover it has been changed to off the shelf only have uart support. Ethernet support and generic JTAG can be added by uncommenting the corresponding lines. |
