Makefile does not automatic clean anymore. In Windows rm -f leads to errors and abort synthesis.
minsoc/syn/setup.bat added. Asks for Xilinx settings32|64.bat script and completely implements MinSoC. On completion or error, it holds window open until user input ENTER.
minsoc/sim/modelsim/: *.bat holds window open until user input ENTER.
run_sim.bat asks for target firmware, check if it exists before running simulator. Holds window open and output error message if not found. Does not hold for simulator. |

Modelsim whines about missing timescales:
-minsoc_bench.v, minsoc_memory_model.v and dbg_comm_vpi.v updated to include timescale.v
modelsim simulation working under Windows. Modelsim PE Student Edition 10.0a
Simulation<->adv_jtag_bridge<->gdb communication not working perfectly. I believe VPI module has to be recompiled, used pre-compiled one for now. |

Including a global timescale under minsoc/rtl/verilog to control simulation. It is under the implementation because the implementation files include it.
Removing timescale definition of minsoc_bench_defines.v files.
Creating a modelsim simulation directory. Everything is working under Linux. For Windows, run_sim.sh has to be changed:
-pli ../../bench/verilog/vpi/jp-io-vpi.so
to:
-pli ../../bench/verilog/vpi/jp-io-vpi.dll
These files have to be compiled/copied from minsoc/rtl/verilog/adv_debug_sys/Software/adv_jtag_bridge/sim_lib/modelsim_platform to minsoc/bench/verilog/vpi. |

backend update:
-minsoc_bench_defines.v
-gcc-opt.mk
Both files should now be under minsoc/backend to proper system functionality.
backend subdirectories have been given those files. Configure script updated accordingly.
They are searched there from system scripts and Makefiles.
-sim/bin/minsoc_verilog_files.txt has the files for Icarus Verilog, minsoc_bench_defines.v is now referenced from backend directory.
-sw/support/Makefile.inc now references to gcc-opt.mk inside backend.
backend/spartan3e_starter_kit_eth:
-It is the system configuration for Spartan 3E Starter Kit with Ethernet. |

Still one configuration mismatch on minsoc_defines.v:
-MEMORY_ADR_WIDTH now 15
-orp.ld is defined accordingly |

Constraint file for backend spartan3a_dsp_kit.ucf was configured to include the STARTUP module.
This module is not enabled under the respective minsoc_defines.v. Thus, its pins had to be commented out. |

spartan3e_starter_kit requires special configuration of or1200_r3.
For that, configure script was specially adapted and that is reported on script execution.
For release-1.0 of MinSoC this should not be required, because or1200_r1 already has the
required configuration. |

firmware makefiles:
-every firmware makefile has now complete dependency. This also includes dependency on files under minsoc/backend (target specific files). That means, that if some target specific header changes, the support library dependent on it will be compiled. That will always happen, even if you compile the uart firmware. In other words, if you want to use uart firmware, you can always simply compile uart by issuing make all. If anything has changed, backend files, support library, drivers, it will update everything for you.
-TODO: dependency can be automatic created by using make together with gcc. Use it instead of declaring all dependencies manually.
Makefile system for synthesis:
-the dependency for every implementation step has been checked and is working fine.
-Makefile plus support files have been moved to minsoc/syn/src
-make usage is still under syn through files generated by backend bashscripts
Backend:
-files under backend are target specific files used for the system to work
-firmware compilation
-system simulation
-system implementation
-This directory is populated by visiting one of its subdirectories and typing ./configure
backend/spartan3a_dsp_kit:
-working on FPGA
backend/spartan3e_starter_kit:
-has to be tested
backend/ml509:
-missing files have to be copied and adapted, configure script has to be copied and adapted
backend/std:
-include files necessary for firmware compilation and system configuration
-it does not include files for synthesis and is not synthesizable |

Wrapping different family modules of same manufacturer in a single module.
minsoc_clock_manager.v: uses fpga manufacturer wrappers
xilinx_dcm.v: selects between different Xilinx FPGA families and implements the module
altera_pll.v: selects between different Altera FPGA families and implements the module |

Selection of memory model or implementation memory is now made on minsoc_bench_defines.v. It is done by a definition instead of including different files for simulation.
minsoc_bench_defines.v definition of reset level was not correct. It based the level decision on defineds POSITIVE_RESET or NEGATIVE_RESET, which couldn't be defined by then, since minsoc_defines.v is not included in minsoc_bench_defines.v. The decision has been moved to minsoc_bench.v and made a localparam instead of a definition. |

undefinition of NEGATIVE_RESET on minsoc_bench_defines.v cannot affect other inclusions of minsoc_defines.v. Instead, the testbench now works with the right reset level to avoid the implementation ordering problem. |

Standard definitions depended on implementation order. Now, this should be solved.
minsoc_bench_defines.v: when setting reset to be positive (`define POSITIVE_RESET), NEGATIVE_RESET is undefined. This override the implementation order, so that independent of it, POSITIVE_RESET will be used.
minsoc_defines.v: when setting GENERIC_FPGA, FPGA_TAP and FPGA_CLOCK_DIVISION are undefined. This way, even if FPGA_TAP would come prior to GENERIC_TAP on the correspondent implementation, GENERIC_TAP would still be selected.
IMPORTANT: GENERIC_MEMORY must still be implemented first on minsoc_onchip_ram.v, because FPGA's memory is automatically selected from other definitions and cannot be undefined a priori. Since some other memory types can be selected, there is no trivial solution. However, this shouldn't be a big problem, since the beginning of this file will probably not be modified. |

If a FPGA manufacturer is selected, the FPGA families of other manufacturers are automatically ignored.
Some updated to comments.
CLOCK_DIVISOR back to 5. The number does not matter much, but 1 is a bad standard number, since it should never be selected. Comment says, use NO_CLOCK_DIVISION instead.
Changing standard FPGA back to Xilinx and Spartan3A. I'm only doing this because the synthesis examples page of wiki still assume this FPGA to be standardly selected. |

Adjusting Makefiles to compile correctly with new firmware updates.
1) except.o not included into libsupport.a.
2) libsupport.a linked to except.o, now in correct order: ld libsupport.a except.o -o executable (not the other way around)
3) int.c was not being compiled because of a #ifdef which is not set anywhere |
