Editable XXICC documentation files rev 0.1a

johnbeetem — Tue, 25 Jun 2019 15:08:20 GMT

These are the .xoe files for "Programming in the GalaxC Language", "The XXICC Anthology", install.pdf, compile.pdf, and TamingWB.pdf. It also includes the .gal files for collecting the individual .xoe chapter files into a book with cross-references. This has not been documented yet.

The .xoe files include chapter copyright and licensing text that is excluded when printing a complete book, since that is in the front pages of the book.

XXICC executable binary for Windows rev 0.1a

johnbeetem — Tue, 25 Jun 2019 15:04:56 GMT

This is a compiled and linked XXICC executable binary "xxicw.exe" for Microsoft Windows on x86 PCs for users who do not want to build it from source code. "xxicw.exe" was built as described in Installing and Running XXICC rev 0.1 and tested on both Windows 2000 and Windows 7. See the enclosed ReadMeExe.txt for more information.

Previous XXICC releases included other GNU/Linux executables as well. I have decided to drop those, since it's pretty simple to recompile "xxicc" for Debian, Raspbian, and Ubuntu using the instructions in Installing and Running XXICC rev 0.1. If you are having difficulties compiling XXICC or need a pre-compiled executable, let me know in the comments.

XXICC code patches release 0.1

johnbeetem — Wed, 27 Feb 2019 19:01:28 GMT

This file contains code patches for XXICC release 0.1. These are simple bug fixes and not worth making a new release.

The only updated file is icemap.gal, which fixes a minor bug in generating BLIF for iCE40 FPGAs. Release 0.1 does not initialize multi-bit registers properly.

patch01jun.zip replaces patch01.zip uploaded in February.

To install this patch, go to your XXICC directory -- the one that has the xxicc executable and object code. Download and unzip patch01.zip, which replaces icemap.gal. Then run "./xxicc fla". This will compile icemap.gal and replace the object code icemap.gi.

Editable XXICC documentation files rev 0.1

Data files for FlaviaLB60 release 0.1 for LOGI-Bone

johnbeetem — Thu, 31 Jan 2019 17:27:13 GMT

FlaviaLB60-01.zip contains data files for the FlaviaLB60 implementation of the Free Logic Array, described in Flavia: the Free Logic Array and Chapter 12 of The XXICC Anthology rev 0.1. FlaviaLB60 is for the ValentF(x) LOGI-Bone FPGA board, rev R1.0. To reduce chances of confusion, I recommend that you only install this file if you want to synthesize Flavia logic for the LOGI-Bone.

FlaviaLP60 rev 0.1 uses n-bit integers in SevenSegLB.xoe.

Unless you're using JTAG, FlaviaLB60 rev 0.1 may not work with the new LOGI-Bone-2, marked R1.5.1 on the PC board. LOGI-Bone-2 has a different I2C GPIO expander and changes its pin assignment, so programming LOGI-Bone-2 directly from BBone is slightly different. Flavia 0.1 programs LOGI-Bone by writing a bitstream to "/dev/logibone" (used by original LOGI-Bone) or to "/dev/LOGIBone" (used by LOGI-Bone-2). However, I haven't tried it since I don't have a LOGI-Bone-2.

If you've been able to get Flavia running on LOGI-Bone-2, please add comments below telling us what worked. If you're having trouble getting LOGI-Bone-2 to work, add comments and/or e-mail me and we'll figure it out.

Note: LOGI-Bone-2 changed the default FPGA configuration mode from Slave Serial to Master Serial/SPI, i.e., self-config. So when you power it on, LOGI-Bone-2 tries to read a valid bitstream from on-board serial Flash. Flavia can override it, but if there's a valid bitstream it will affect whatever you have hooked up to LOGI-Bone-2 pins.

There may be other LOGI-Bone-2 changes that affect Flavia. I don't have the new board to test things at this time.

Flavia is part of XXICC. For more information on GalaxC and XXICC, see the 'blog post XXICC (21st Century Co-design) release 0.1 and XXICC's home page xxicc.org.

Data files for FlaviaLP60 release 0.1 for LOGI-Pi

johnbeetem — Thu, 31 Jan 2019 17:20:30 GMT

FlaviaLP60-01.zip contains data files for the FlaviaLP60 implementation of the Free Logic Array, described in Flavia: the Free Logic Array and Chapter 12 of The XXICC Anthology rev 0.1. FlaviaLP60 is for the ValentF(x) LOGI-Pi FPGA board, rev R1.2. To reduce chances of confusion, I recommend that you only install this file if you want to synthesize Flavia logic for the LOGI-Pi.

FlaviaLP60-01.zip is the same as rev 0.0r except it uses n-bit integers in SevenSegLP.xoe.

Unless you're using JTAG, Flavia rev 0.1 won't work with the new LOGI-Pi-2, marked R1.5.1 on the PC board. LOGI-Pi-2 has an I2C GPIO expander, so programming LOGI-Pi-2 directly from RasPi is different. I'll add LOGI-Pi-2 to a future release if there's enough demand.

Flavia is part of XXICC. For more information on GalaxC and XXICC, see the 'blog post XXICC (21st Century Co-design) release 0.1 and XXICC's home page xxicc.org.

GCHD examples for IceStorm rev 0.1

johnbeetem — Thu, 31 Jan 2019 17:04:22 GMT

GCHD example files for generating Lattice iCE40 FPGA using IceStorm, as described in Chapter 15 of The XXICC Anthology rev 0.1. Synthesis targets are Lattice iCEstick and Nandland Go Board. Rev 0.1 uses n-bit integers for the SevenSeg examples.

GCHD is part of XXICC. For more information on GalaxC and XXICC, see the 'blog post XXICC (21st Century Co-design) release 0.1 and XXICC's home page xxicc.org.

Installing and Running XXICC rev 0.1

johnbeetem — Thu, 31 Jan 2019 03:04:44 GMT

This document describes how to install and run XXICC on your computer, either by compiling XXICC source code or installing binaries.

This is revision 0.1, which is almost identical to 0.0q. Current users don't need to do anything differently.

For more information on XXICC and GalaxC, see the ’blog post XXICC (21st Century Co-design) release 0.1 and XXICC's home page: xxicc.org

install01.pdf has instructions for installing XXICC for all versions (GNU/Linux and Windows) and for all purposes. This means finding all the steps you need for a particular platform can be a little involved. Here are the specific steps for installing XXICC and Flavia on a 32-bit GNU/Linux machine that uses an FTDI FT2232H or FT232H USB serial IC as a JTAG controller.

Create a directory for XXICC. You can call it anything you want, but the instructions assume you have called it XXICC and it’s in your home directory.

cd ~
mkdir XXICC
Change to your XXICC directory: cd ~/XXICC
Download the XXICC source code code00q.zip into your XXICC directory and unzip it:

unzip code00q.zip
Before compiling XXICC, you need to install the libxft developer’s libraries:

sudo apt-get update
sudo apt-get install libxft-dev
Make a subdirectory for XXICC object code: mkdir xxicc.od
Compile XXICC’s C files: make T=XGL

This should create the XXICC executable xxicc.
Install libftdi.so, which XXICC needs to talk to an FTDI FT2232D/H or FT232H USB serial IC:

sudo apt-get install libftdi1

This installs libftdi.so.1. However, XXICC needs it to be named libftdi.so, so you must add a symbolic link in /usr/lib/arm-linux-gnueabihf (or similar /usr/lib subdirectory such as /usr/lib/i386-linux-gnu):

cd /usr/lib/arm-linux-gnueabihf
sudo ln -s libftdi.so.1 libftdi.so
cd ~/XXICC
Compile XXICC’s GalaxC source code, including the files needed for Flavia:

./xxicc fla

XXICC will compile the GalaxC files and link in libftdi.so. If the library is not present, you will get an error message. Review Step 7 and/or install00q.pdf to see how to deal with this.

When XXICC finishes compiling, it should bring up a file selection dialog. For now, close the dialog and xxicc terminates. The next time you run xxicc it will load object code and come up in less than a second.
Before you use JTAG, download 85-ftdi.rules (udev rules file for FTDI FT2232D/H, FT232H, and Papilio DUO) and copy it (using sudo) to /etc/udev/rules.d. 85-ftdi.rules to set permissions so that XXICC can talk to FTDI serial devices without having to run as superuser. 85-ftdi.rules takes effect when you reboot or you can reload udev rules with the command:

sudo udevadm control --reload

85-ftdi.rules requires that you are a member of the dialout group. See if you’re in dialout by giving the groups command. If you’re not in dialout, give the command:

sudo adduser <userid> dialout

You will need to log out and log back in again for the change to take effect.

That should do it! Please comment if you have any questions or helpful suggestions.
