    Arty7

    Hi I have a brand new Arty project board never been used has been unpacked. Im asking $100.00 no lower? If interested please email me at traymond20@gmail.com Thank you, traymond
  2. I went with using Lattice Diamond 2016 software and I have an older 2005 MACH XO Breakout project board I think this supports prototyping, but would this board support working with really basic simple FPGA projects? Can I still use this forum for none Xilinx projects, Lattice only supports College students and businesses and the regular guy wanting to learn FPGA is almost left in the cold, not quite. I like the Diamond software menu, it seems to better support older chip compilers etc, is why I went back to Lattice. With my MachXO board it has a USB cable but Im thinking would it need a driver, I dont really understand how Im supposed to get the correct driver and need some help please. Im stuck on learning VHDL code, is there any latest books covering this, please provide ISBN number. I finally figured out as far as code goes, do you use a text editor to: Create VHDL/Verilog code, Edit code? Do the beginners projects teach simple code to learn code? Just a newbie Thank you traymond

    ASIC Custom libraries

    Dan, yeah 1million is out of my budget too. Commodore MOS or CSG (Commodore Semiconductor Group) always made a million wafers at a time, so it would cost them a Million dollars per run, probably double or triple that these days, which is why Approximation with FPGA is the best. So ASIC seems too expensive. I have decided to go with a different FPGA vendor since Xilinx would let me approximate CBM MOS IC's in a project board or newer circuit but doesn't support the older 8-bit Circuits, with the same Pinouts for the programmable chips. I would want to try and compile into programmable chips with the DIP thru hole pins what was used on older 8-bit computers. There is www.visual6502.org they do decapp older chips and have decapped a few CBM MOS chips so there would be a guide, if one knows how to read or dechipher chip wafers that have been decapped, its awe inspiring. The awesome SID (Sound Interface Device) chip there is the decapped: SID 6581R4AR and the SID 8580R5 (I believe). there was the SID 6582A but those are hard to find. But the SID was a very complex little sound synthesizer chip, its designer was Bob Yannes, at least with the 6581, Commodore MOS just changed the SID filters for the 6582A and the 8580 R5, commodore didn't know anything about Music Synthesis is why they couldn't make anymore cool changes to SID. The earlier 6581 used 12VDC, so it ran way hotter and the heat killed them, so CBM changed the higer voltage to 9VDC. Ahh I remembered I'm changing to Lattice one of their software in the menu has a compiler menu to support compiling actual programmable chips, that's my issue with Xilinx they support newest circuits but not the older8 bit circuits I want to support, hopefully. I can see Chip Approximation is no easy task, wow. So yeah ASIC is out of the question. There is a Forum that has been around for years: Commodore Hacking this group discusses a lot of ASIC and MOS chips and some approximation, there must be a way of using an older Eprom programmer to read the Pins of the chip to figure out all of the Pins, IO pins and voltages etc, I did not know the software for Eprom programmers would do this, but its interesting, yeah yeah its my old hobby. Thanks for your info on ASIC Western Design Center might have ASIC librairies but the main problem is that making these older MOS chips is way too expensive for WDC, because it cost Commodore a million dollars just for building a million chips per run, double or triple that these days, which is why approximation may be the way to recreate them. traymond I

    ASIC Custom libraries

    Well approximating older MOS CBM chips like in the C=64 8-bit computers etc. One individual on Xilinx forum explained just what ASIC is and how the library creates what you need if a company provides the Libraries. Commodore went bankrupt and so records of those gates havent been around for years, so youre guessing and figuring out approximately all gates, IO pins, voltages etc The biggest problem is to possibly *maybe* create a remade IC somehow but be able to have the ability to plug that remade programmable IC into the 8-bit circuit but would ASIC be better because Xilinx doesnt support older 8-bit technology. In the 80's and late 1990's CBM MOS made runs of a million ICS orr run, costing a million dollars, it would be double or triple prices to produce MOS chips in the traditional way CBM MOS made them, so uts just too costly, so FPGA using ASIC I have heard is the way to go. My issue is starting simple and learning the basics of FPGA though. I heard that ASIC doesnt compile so how then can the gates and everything be made, so does ASIC hand this over to FPGA to sonehow make all gates etc in a chip? I understand that FPGA can compile Code to the level of the FPGA and makes all that is needed. So ASIC I assume doesnt handle the compiling, just the making of inner gates and hardware? But to me to recreate a programmable chip with approximation you need some type of programmer, but is it a compiler is what I dont understand. Granted nowadays technology has advanced past older 8-bit computers but this is a hobby im fond of and willing to work hard to try and recreate. I know of a small company that has decapped most older chips: www.visual6502.org but then you have to learn what each decapped circuits use is but the decapping reveals all this and about the only way to figure out all of the CBM MOS chips. Refreshing history, without Chuck Peddle we wouldnt of had CPU's and William Mensch and others worked together in the late 1960's etc. William Mensch provides some earlier MOS chips but not what was used on later CBM 8-bit computers. Mr Mensch cant make MOS chips but could NMOS but they arent tested that would be very expensive to test so not cost effective to produce. Mr Mensch told me in an email that NMOS uses 9VDC and would only support the latter C64C Rev-E, C128DCR, Plus4 etc. So the earlier C=Pet, Vic-20, C64(breadbin) these computers chips work at 5 volts etc. Just need to start simple but with simple FPGA projects. traymond

    ASIC Custom libraries

    I heard that ASIC has a CUSTOM library. Does Vivado Suite2016 still support these libraries? Is there a PDF that would explain ASIC and its libraries? or is it Library? I assume the code is still written with Verilog or VHDL? I heard that ASIC doesnt compile, does it program somehow? Im interested in chip approximation using ASIC what tools would I need, programmers etc? Since Im just starting out with Vivado should I only install the basic software, I installed everything would that make learning the menus harder etc? traymond
  6. Where can I find: Vivado getting started guide? Im just getting started and need to brush up on Vivado and familiarize myself with it more before I proceed to trying new Arty projects. Thanks. traymond
  7. Hi all. I have many questions: I am new to FPGA and using: Vivado Design Suite 2006 and have a FREE 30 day license. Have Arty-7 Evaluation board Are there beginner projects here for beginners that would work with Vivado and Arty? Which beginners projects should I start with then? Does Vivado have its own built in USB drivers for its cable? Other than that I'm ready I just need to know how to start. Thank you. traymond
