open-hardware-repository-cern-path Наравне с репозиторием, специалистами CERN так же был написан текст новой лицензии, ответственной за дистрибуцию такого железа: Open Hardware Licence (OHL). Вот что по этому поводу говорит один из инженеров CERN — создатель репозитория Хавьер Серрано (Javier Serrano): «Для нас стремление к открытому оборудованию во-многом мотивировано завистью к коллегам, которые разрабатывают драйверы для устройств под Linux — они являются частью огромного сообщества людей, которые делятся собственными знаниями и временем для того, чтобы в итоге построить наилучшую операционную систему.  Конечно, специалисты CERN не оказались первопроходцами в этой области, не во всем. The project I’m talking about is CERN’s Open Hardware Repository. The OHR has its roots in the White Rabbit project, a timing system developed for experimental physics facilities able to synchronize ~1, nodes with sub-nanosecond accuracy over fiber optic cable lengths of up to 10 km.  After developing a clear idea of how to bring his ideas for an open electronic design approach into reality, Serrano gained the support of CERN’s knowledge transfer group. In , the OHR started its outstanding track record of success. Over the last few years, the OHR has become the de facto place on the web where electronics designers at experimental facilities collaborate on open hardware designs, sharing much of the attitudes and beliefs of the free software movement. Open Hardware Repository — проект созданный сотрудниками CERN для организации сообщества вокруг проектов с открытой аппаратной архитектурой и их реализации. Open Source Hardware Association — создана для продвижения Open Source устройств, дизайн которых свободно доступен под открытой лицензией. Такие устройства, микросхемы, печатные платы вот уже полтора года помечаются логотипом с шестерёнкой, так что каждый сразу видит, что это — свободное устройство. Базовые требования, которые нужно соблюдать при разработке открытого аппаратного обеспечения.

Alternatively, you may choose to forgo installing anything in your Python environment and simply directly run from the source by creating a launch script. In my my open hardware repository cern path youth I hung about with a lot of kids who were into grafitti. It shares the same principles as free software or open-source software: anyone should be able to see the source — the design open hardware repository cern path in the case of hardware — study it, modify it and share it.

It shares the same principles as free software or open-source software: anyone should be able to see the source — the design documentation in the case of hardware — study it, modify it and share it. The first two variants mean that if any product is made using an open hardware design, the design of that product, including any improvements or modifications, should be made available under the same licence as that of the original product.

Permissive licences do not impose this condition. News News Topic: Knowledge sharing. Knowledge transfer open hardware. We start by cloning the repository and getting into the SPEC reference design tested with Release v4. In this example, you have the option of fetching all of the dependencies for all of the reference designs provided in the downloaded source code by using the git submodule mechanism, this is:.

Alternatively, if you only want to download the design submodule dependencies the design needs, we can use the hdlmake fetch feature as the required remote modules are already listed in the provided Manifest. Once we have all the dependencies, we can run hdlmake to automatically generate a synthesis Makefile.

Once we have done this, we can just run Make to automatically generate the bitstream:. If you experience any problem, please perform a make clean before running Make. Once this is done, hdlmake will only clone the listed repositories in the fetchto folder and then will checkout the appropriated commits by previously interrogating the git submodule mechanism.

In this example, doing. This project makes use of custom Xilinx Vivado properties and custom Python code , so it is a very valuable example as a template for custom setups. Here, you can see a copy of the top Manifest. If you are generating HDL code from a Xilinx IP library, you may need to select the target language by setting the language top manifest variable to either vhdl or verilog.

If the language variable is not defined, hdlmake will choose vhdl as the default HDL language. If you want to regenerate the Quartus project by using your custom Quartus properties , you may replace the provided Manifest. From the provided simulation examples, we will use the following one. In some version of Modelsim e. Modelsim PE As an example, we may apply the modifications highlighted in the following diff patch:.

Once everything is ready, we can compile the design sources. As the HDLMake SystemVerilog parser is not very accurate yet and it is not able to successfully solve the complete hierarchy, we will need to pass the -a flag to the makefile generation command so that all the files are parsed and passed to the compiler — even if we cannot relate them to the top entity by using dependency relations:.

Alternatively, we may provide the full path to the Unisim library required Xilinx sim components , e. In this point, if everything goes OK, Modelsim window will open and we will see the waveform progress for the design under test:.

This is the default command for hdlmake and its basic behaviour will be defined by the value of the action manifest parameter in the hierachy Manifest.

In order to allow for a more agile development, we have included these shortcuts when using the hdlmake makefile command:. Otherwise, the process will fail. It is assumed that a projects can consist of modules, that are stored in different places locally or a repo. The same thing is about each of those modules - they can be based on other modules. Hdlmake can fetch all of them and store them in specified places.

For each module one can specify a target catalog with manifest variable fetchto. Its value must be a name existent or not of a folder.

The folder may be located anywhere in the filesystem. It must be then a relative path hdlmake support solely relative paths. List all the modules involved in the design described by the top manifest and its children hierarchy. The output list will be printed in stdout, being each of the modules represented by a single text line made up of two entries separated by a tab.

The first entry in a line associated to a module is the relative path to the specific directory where the module is stored, while the second entry is a identifier indicating the origin of the module. If we provide the --with-files argument to list-mods , the files being directly included by a specific module will be printed just after the line pointing to this specific module.

Each of the printed lines associated to a file will be composed by two entries too, the first one pointing to the relative path to the file and the second one indicating that the resource is a file. In addition to the lines representing modules and files, list-mods will also print to standard output some comments providing additional information about the structure of the module hierarchy.

This modules will start with a sign, following in this way the usual shell convention. Summing everything up, the following table compiles the different kind of resources that can be printed when listing the modules:.

Now, here we have some examples of the outputs we should expect when using the list-mods command:. List all the files that are defined inside all of the modules included in the hierachy in the form of a string of elements separated by a DELIMITER and print this list to stdout. In order to build the file list, hdlmake will parse the HDL files to find the required dependencies that a top entity needs to be successfuly compiled.

We can configure the name of the HDL module that will be considered as the top entity to build the required file hierarchy by using the --top TOP optional argument to the list-files command. If no top entity is defined, all of the design files will be listed. Finally, by using the --reverse optional argument we are able to reverse the order of the listed files.

Hdlmake can be run with several arguments. The way of using them is identical with the standard one in Linux systems. The order of the arguments is not important. Hereafter you can find each argument with a short description.

Gives a short description of each available option. Print the version of the hdlmake instance on execution an quit. Disable the stage in which hdlmake purges the files that are considered as not dependent on the top entity. In this way, by activating this flag all of the files listed by the module hierarchy will be used for the issued action.

Set logging level for the Python logger facility. You can choose one of the levels in the following tables, in which the the associated internal logging numeric value is also included:. Use a file to store all of the log information generated by hdlmake.

Add arbitrary Python code from the command line that will be evaluated before each Manifest. As an example, this command will generate the Makefile and will try to print Hello hdlmake before each Manifest. Add arbitrary Python code from the command line that will be evaluated after each Manifest.

As an example, this command will generate the Makefile but will try to print Bye, bye hdlmake after each Manifest. Navigation index hdlmake 3. Microsemi Actel Libero Yes n. Lattice Semi. It can also be used by any designer wishing to share design information using a licence compliant with the OSHW definition criteria.
