68 Still one configuration mismatch on minsoc_defines.v:
-MEMORY_ADR_WIDTH now 15
-orp.ld is defined accordingly
rfajardo 3819d 04h /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 3819d 04h /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.

65 Files missing in the last commit.
backend/std/configure
sw: eth, uart and driver Makefiles
rfajardo 3819d 06h /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 3819d 07h /minsoc/trunk/
63 Adding a functional synthesis Makefile system. Still needs a reviews and enhancements, but at least it is something. rfajardo 3823d 01h /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 3823d 08h /minsoc/trunk/
61 Removing supposely defined external function, which don't exist anymore. rfajardo 3823d 08h /minsoc/trunk/
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 3823d 19h /minsoc/trunk/
59 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. rfajardo 3823d 20h /minsoc/trunk/
