71 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.		 rfajardo 4732d 14h /minsoc/trunk
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 4732d 14h /minsoc/trunk
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 4737d 06h /minsoc/trunk
68 Still one configuration mismatch on minsoc_defines.v:
-MEMORY_ADR_WIDTH now 15
-orp.ld is defined accordingly		 rfajardo 4739d 10h /minsoc/trunk
67 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.		 rfajardo 4739d 10h /minsoc/trunk
66 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.		 rfajardo 4739d 11h /minsoc/trunk
65 Files missing in the last commit.
backend/std/configure
sw: eth, uart and driver Makefiles		 rfajardo 4739d 12h /minsoc/trunk
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 4739d 13h /minsoc/trunk
63 Adding a functional synthesis Makefile system. Still needs a reviews and enhancements, but at least it is something. rfajardo 4743d 07h /minsoc/trunk
62 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		 rfajardo 4743d 14h /minsoc/trunk
