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.

24 E-mail in the documentation has been corrected. rfajardo 3648d 02h /minsoc/trunk/doc/minsoc.pdf
23 Paragraph minor changes, used in announcement and double checked. rfajardo 3652d 07h /minsoc/trunk/doc/minsoc.pdf
21 Including the first draft project documentation. How to and status progress docs are now separate from documentation. rfajardo 3652d 09h /minsoc/trunk/doc/minsoc.pdf
20 minsoc_defines.v had a semicolon at the end of the two reset polarity definitions.

minsoc_top had a signal array for two different signals which was for backward compatibility. The compatible debugging module is so old that there is no reason for keeping it.

Documentation has been updated to better explain how to use the definitions files, minsoc_defines.v and or1200_defines.v. An example for Altera devices has been added too.

19 Documentation update. How To: 7) Examples:
-Spartan 3E Starter Kit no Ethernet has been already tested and is known to work.
-Spartan 3E Starter Kit with Ethernet not yet.
-change of sw/support/orp.ld cannot be done by only commenting and uncommenting line, the instruction, documentation line, which said so has been removed.
-Further possibilities -> Further area optimization possibilities.
rfajardo 3690d 13h /minsoc/trunk/doc/minsoc.pdf
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.

12 1) spi_top.v:
-TX_NEGEDGE bug reported and recommended solution by Blaise Gassend. (Thank you)
2) minsoc howto extended to:
-synthesis of minsoc for Spartan3E Starter Kit with Ethernet
3) spartan3e_starter_kit.ucf changed:
-it had problems regarding pin definitions and IO logic types for mapping and place&route. Working flawless now.

6 No implementation relevant changes.

Testbench used generic memory from minsoc_onchip_ram.v has been changed to reflect the correct model of the FPGA's onchip rams: address register and write accesses are sensitive to rising clock edge.

Documentation updated to reflect another trial and next steps to speed up the memory access from 2 clocks to 1. The negated clock approach is not standard. The right way to do it would be to use the wishbone signals cti and bte and change the minsoc_onchip_ram_top.v.

5 vpi path corrected in how to. rfajardo 3780d 13h /minsoc/trunk/doc/minsoc.pdf
4 minsoc_bench.v had a big memory declaration to load the firmware, which was not necessary.

jp-io-vpi.vpi has to be compiled for different systems so removed from the project. Documentation now explains how to do it.

Documentation now includes:
-vpi module compilation
-gdb patch for adv_jtag_bridge
-ideas for future work on minsoc (To Do v.2)
rfajardo 3780d 13h /minsoc/trunk/doc/minsoc.pdf
3 Changed documentation
-advice to compile sw/utils before compiling target software
rfajardo 3784d 11h /minsoc/trunk/doc/minsoc.pdf
2 First commit of project. Beta status:
-testbench: working
-firmware: working
-RTL: Working for: Xilinx Spartan-3A DSP Development Kit
