In the Origen 2 documentation system, how do you reference things like the dut and origen when building a web document?
For example, I currently have an example code block like this where the version is hardcoded:
$ origen -v
Origen: 2.0.0-pre0
I would like to make the version a reference to origen.version, how would I do that?
This can be done using Jinja and some of the context provided by default. The entire origen module is available, so {{ origen.version }} in any RST file, but is also not in a .. raw block, should do it.
You can stick this in a code block as well: ``{{ origen.version }}`` to get something like:
(this is still using the old styling. It'll update with the new styling when available)
I realize the Jinja context is omitted in the documentation. I opened an ticket on O2 to acknowledge some of the documentation lapses.
Thanks!

I wrote a code and used concert technology(cplex and C++). Now I want to get some information about variable selection. For example I want to know that at each node which variable is selected among 10 variables.
how can i write this and add it to my code?
As #IagoCarvalho suggested, you should have a look at the Branch callback:
https://www.ibm.com/support/knowledgecenter/SSSA5P_12.9.0/ilog.odms.cplex.help/CPLEX/UsrMan/topics/progr_adv/callbacks_basic/15_catalog.html.
Examples using a branch callback can be found in an installation of the product. Look for "branch callback" in the cplex/examples/src directory and you will find, among others, cpp/iloadmipex3.cpp.
I am working on transferring one application from rgen to Origen.
I added environment/j750.rb in my application.
added the below code into j750.rb
# environment/j750.rb
$tester = OrigenTesters::J750.new
in Target folder, I also added $test as below:
$tester = OrigenTesters::J750.new
however, when I tried to generate pattern, it still failed and showed'uninitialized constant OrigenTesters'.
When and how to initialize it?
Thanks a lot in advance!
Normally this is something that Origen users don't particularly need to worry about, if you add:
gem 'origen_testers'
to your application's Gemfile, then it will be required automatically and a reference like OrigenTesters in your environment file or anywhere else will just work.
However, I note that you mention upgrading from an rgen app, which means that your application must be very old and in fact may not even have a Gemfile.
If you contact me internally I can send you the link to our intranet page which has a guide on how to update these really old apps.
Sorry if the title is a bit confusing, but what are the options/conventions that Origen provides for setting up subblocks that aren't necessarily silicon models, or are just general helpers?
For example, I have a scan helper plugin that guides the user through creating a scan test program. I'd like to add a list of options/customizations to the top-level app. There are a few ways to do this:
I can add a list of attr_readers/methods. I think this looks a bit ugly though and adds a bunch of stuff to the toplevel that isn't used by anything else, and it blows up $dut.methods.
I could use parameters as defined here: http://origen-sdk.org/origen/guides/models/parameters/ and just call of them in the scan tester app. But looking at the guides I don't think that is the desired use case. It looks more like context switching, but maybe that was just the example use case.
I could add a scan_tester.setup method or something on the toplevel. This just seems unnecessary though since its basically doing the same thing as #2, but requires a 'setup' method to be called. Yeah, its only 1 line, but if you mess up or forget to add that line then you've got some debug to do avoided by #2 (I can print a warning for example if the scan parameters aren't provided to help warn of typos, etc.).
I can set it up as a subblock (currently how I've got it), but this doesn't really fit. Scan isn't a silicon model, so base address is useless, but required. It has no registers, etc.
Then there's other 'Ruby' things I could do (setup via on_create, use global variable etc.) but these all seem not as great as any of the options above for one reason or another (mainly, more setup required on my part than using any of the existing options).
Any one of these would work. But from a convention standpoint, which direction should my scan tester setup go? Is there another option I hadn't considered? I'd lean towards option #2 as it looks the cleanest.
Thanks
This is a really good question.
There are actually two other options:
Add application config parameters from the plugin: http://origen-sdk.org/origen/release_notes/#v0_7_24
Define a constant as used by the JTAG and other early plugins: http://origen-sdk.org/jtag/#How_To_Use
I think #2 is using parameters in a way that was not originally intended, maybe it could work though but I just can't picture it.
I don't really like #5 or #6 since they provide application-level and class-level configuration, which is sometimes what you want, but often these days I see the need more for (DUT) instance-level configuration.
So, my best answer here is that I don't know, but you are touching on a good point that we need to have an official API or at least a recommendation for this.
I think you should be open to the possibility of adding something new to Origen for this if you can think of something better.
As I'm writing this, I suppose #5 would also support instance-level configuration, albeit a bit long-winded:
def initialize(options = {})
Origen.app.config.scan_chain_length = 6
end
My comment wouldn't keep its format, so here it is but looks better:
#Ginty
What would you think of a 'component' API. For example, we could have:
# components.rb
component(:scan, TIPScan::ScanTester,
# options
wgl_dir: ..., # defaults to Origen.app.root/pattern/wgl
custom_sort: proc do {|wgl_name| ...},
)
# then we can do things like:
$dut.scan #=> TIPScan instance
$dut.component(:scan) #=> same as above
$dut.components #=> [TIPScan instance, ...]
$dut.has_component(:scan) #=> true etc.
Pretty much just a stripped down subblock class to handle these. I think our IAR/C compilers and even CATI could benefit from this and make the setup cleaner and more customizable.
What I mean by this is:
I have a program. The end user is currently using it. I submit a new piece of source code and expect it to run as if it were always there?
I can't find an answer that specifically answers the point.
I'd like to be able to say, "extend" or add new features (rather than fix something that's already there on the fly) to the program without requiring a termination of the program (eg. Restart or exit).
Yes, you can definitely do that in python.
Although, it opens a security hole, so be very careful.
You can easily do this by setting up a "loader" class that can collect the source code you want it to use and then call the exec builtin function, just pass some python source code in and it will be evaluated.
Check the package
http://opensourcehacker.com/2011/11/08/sauna-reload-the-most-awesomely-named-python-package-ever/ . It allows to overcome certain raw edges of plain exec. Also it may be worth to check Dynamically reload a class definition in Python
I came across echofunc.vim today (from a link in SO). Since I'm rubbish at remembering the order of function parameters, it looked like a very useful tool for me.
But the documentation is a bit lean on installation! And I've not been able to find any supplementary resources on the internet.
I'm trying to get it running on a RHEL box. I've copied the script into ~/.vim/plugin/echofunc.vim however no prompt when I type in a function name followed by '('. I've tried adding
let g:EchoFuncLangsUsed = ["php","java","cpp"]
to my .vimrc - still no prompting.
I'm guessing it needs to read from a dictionary somewhere - although there is a file in /usr/share/vim/vim70/ftplugin/php.vim, this is the RH default and does not include an explicit function list.
I'm not too bothered about getting hints on the functions/methods I've defined - just trying to get hints for the built-in functions. I can see there is a dictionary file available here which appears to provide the resources required for echofunc.vim, I can't see how I set this up.
TIA,
It expects a tags file, the last line of the description describes exactly how to generate it:
ctags -R --fields=+lS .
It works here with PHP but not with JS. Your mileage may vary.
I didn't know about this plugin, thanks for the info.
You should try phpcomplete.vim, it shows a prototype of the current function in a scratchpad. It is PHP only, though.
