151 Creating tag release-1.0 from revision 150 of branches/rc-1.0. rfajardo 3219d 17h /minsoc/tags/release-1.0/sim/
147 Updating minsoc_bench.v to correctly acquire uart data.

Uart drivers: when an end of line character was sent, the driver appended a carriage return to it. This is not necessary and has been removed.
-Eth and Uart firmwares also had a carriage return after the end of line, also removed.

Minsoc_bench_defines.v: Renaming VCD_OUTPUT define to WAVEFORM_OUTPUT

run_bench: selecting -lxt2 for waveform output format. This output format size is 10 times smaller than vcd.

minsoc-install.sh: lxt2 output format requires that Icarus Verilog be installed with zlib support. For that, we now check if zlib is supported on script run.
rfajardo 3224d 16h /minsoc/branches/rc-1.0/sim/
134 run_sim.bat for ModelSim updated to acquire the firmware_size for command line input when running the testbench. rfajardo 3240d 17h /minsoc/branches/rc-1.0/sim/
133 Roll back minsoc_bench.v to timed simulation. Merge minsoc_bench_core and minsoc_bench_clock again.

Applying Rubén Diez patch to avoid warnings on firmware load for simulation.
rfajardo 3240d 18h /minsoc/branches/rc-1.0/sim/
132 ModelSim simulation, running top_module minsoc_bench_clock now, instead of minsoc_bench. rfajardo 3244d 14h /minsoc/branches/rc-1.0/sim/
121 Asserting svn:executable properties of modelsim/*.bat scripts.

Including corrected patch for advanced debug system watchpoints under utils/setup. Configure script updated to use this instead of advanced debug system patches. This will remain so until the patch is corrected. The previous line still has the correct command.
rfajardo 3251d 08h /minsoc/branches/rc-1.0/sim/
119 Tricking Subversion to accept bat files that are now executable. rfajardo 3251d 12h /minsoc/branches/rc-1.0/sim/
109 Creating a branche for release candidate 1.0. rfajardo 3252d 08h /minsoc/branches/rc-1.0/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)
rfajardo 3259d 18h /minsoc/trunk/sim/
85 Central project definition under prj. Synthesis and simulation take their project files from here. rfajardo 3302d 12h /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 3328d 10h /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.
rfajardo 3421d 14h /minsoc/trunk/sim/
72 Adding Windows batch files to run a Modelsim simulation.
-prepare_modelsim.bat, compile_design.bat, run_sim.bat
rfajardo 3421d 15h /minsoc/trunk/sim/
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 3421d 18h /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 3426d 10h /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
rfajardo 3428d 17h /minsoc/trunk/sim/
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.
rfajardo 3433d 05h /minsoc/trunk/sim/
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.
rfajardo 3628d 13h /minsoc/trunk/sim/
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 3705d 20h /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.
