149 Merging differences of release candidate 1.0 revision 140:148 with trunk. rfajardo 2914d 06h /minsoc/trunk/sim/
141 Merging with rc-1.0 revision 140. I doubt rc-1.0 will still change much in the last days. rfajardo 2920d 05h /minsoc/trunk/sim/
104 Enabling modelsim simulation for current project definition.
vhdl and verilog projects have to be separated:
-prj/Makefile defines VHDL_PROJECTS and VERILOG_PROJECTS, they are merged into PROJECTS. Tools which don't care about VHDL or Verilog use PROJECTS list while other tools use VERILOG_ or VHDL_PROJECTS.
-Simulation uses VHDL_PROJECTS and VERILOG_PROJECTS independently.
-prj/scripts/simprj.sh splitted in:
-simvhdl.sh
-simverilog.sh
(they generate the input files in the right format for simulation tools)

85 Central project definition under prj. Synthesis and simulation take their project files from here. rfajardo 2997d 01h /minsoc/trunk/sim/
75 Adapting minsoc_top.v and minsoc_verilog_files.txt to new names for top modules and define file of ethmac ip core. rfajardo 3022d 23h /minsoc/trunk/sim/
73 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.

72 Adding Windows batch files to run a Modelsim simulation.
-prepare_modelsim.bat, compile_design.bat, run_sim.bat

70 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.
rfajardo 3116d 06h /minsoc/trunk/sim/
69 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.
rfajardo 3120d 22h /minsoc/trunk/sim/
64 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

60 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.

34 start_server changed: '-t' option of adv_jtag_bridge for vpi connection on simulation removed. or1200_v3 will not pass on CPU self test.

FAQ completed with asked questions since Februrary 2010.

INSTALL informs bsdl files only have to be copied to home directory for Xilinx devices.

synthesis_examples title includes Minimal OpenRISC System on Chip.

31 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
rfajardo 3400d 08h /minsoc/trunk/sim/
30 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.

18 Deprecated comments removed from the file listing files. rfajardo 3653d 07h /minsoc/trunk/sim/
17 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.

10 Added a file containing models for each FPGA memory instances used in or1200. The file is in bench/verilog/sim_lib/fpga_memory_primitives.v.

With it, people who change the or1200_defines.v inside of the project structure will still be able to simulate, using house-made models, not from manufacturers.

minsoc_bench.v had to be extended by the task, init_fpga_memory, to initialize the dual or two port memories instances of or1200. This has to be done based on the type of memory used, so many different instantiations based on definitions. Somehow or1200 expects all memory values to be 0 upon start, so this is necessary.
