Hi I'm a beginner in learning UEFI and trying to find out the logic of using protocols.
I've read the source code of CoreOpenProtocol, CoreCloseProtocol and CoreLocateProtocol.
What I've found that while CoreOpenProtocol will create a OPEN_PROTOCOL_DATA structure and linked into PROTOCOL_INTERFACE->OpenList, CoreLocateProtocol does not create such structure.
CoreCloseProtocol will actually delete the OPEN_PROTOCOL_DATA from PROTOCOL_INTERFACE->OpenList and free the memory that it took.
So since CoreLocateProtocol do not create OPEN_PROTOCOL_DATA, the close procedure seems meaningless.
Is that true?
Thanks a lot!

I am trying to develop a OPC UA server on my own, but since I am quite a newbie in coding, it is quite hard for me.
I have started from the QuickstartApplication found here: https://github.com/OPCFoundation/UA-.NET-Legacy
in particular I edit the ModelDesign.xml file to customize it as I wish
https://github.com/OPCFoundation/UA-.NET-Legacy/blob/master/ComIOP/Common/Common/ModelDesign.xml
I would like to define some nodes with NodeId as string (all the NodeId in the ModelDesign.xml in the example are numeric)
Following this xsd, I have found "StringId" and "NumericId" that look like what was looking for
https://github.com/OPCFoundation/UA-ModelCompiler/blob/master/ModelCompiler/UA%20Model%20Design.xsd
but changing their value in ModelDesign.xml does nothing about the NodeId. There is no error, just the compiler assigns new NodeIds (all numeric) as if it does not consider the changes I have made.
As a compiler, I am using the ModelCompiler found on GitHub
https://github.com/OPCFoundation/UA-ModelCompiler
Can somebody help me, please? How can I customize the NodeId of the nodes?
Thank you

the best suggestion that I can offer at this stage is to clone the UA-.NETStandard and run the NetCoreConsoleServer in
UA-.NETStandard/SampleApplications/Samples/NetCoreConsoleServer
through the debugger. The boiler node manager, if my memory serves me well, uses stringIDs. The Interface INodeIdFactory in ISystemContext.cs offers some insight in how ID's are generated.
IMHO, the model designer has no switch to enforce string ID's as you know. So you'll need to programmatically allocate stringID's rather than numeric ID's to nodes upon server boot. I haven't figured it out yet either.
So, you may set breakpoints in the BoilerNodeManager.cs and see how the nodeID is actually constructed.
We are in process to migrate our TB to UVM.
I am working on first IP that will be verified using UVM.
I have to find out if it is possible to reuse my uvm_sequences in SOC that remains in OVM mean time.
In case it is possible , like find example how it's done.
Thanks in advance.
You cannot mix OVM and UVM that way. You should be able to write your uvm_sequence in such a way that it work in both by simply changing your u's to o's. You would have to limit your sequence to functionality that exists in both.
If you use UVM RAL. there is a package that integrates that functionality back into OVM.
There is another package, ovm_container, that gives you the functionality of uvm_config_db.
I'm working on a script to convert a Simulink library to a plain model, meaning it can be simulated, it does not auto-lock etc.
Is there a way to do this with code aside from basically copy-pasting every single block into a new model? And if it isn't, what is the most efficient way to do the "copy-paste".
I was not able to find any clues as how to approach this problem here, or on Google, or on the official documentation or on the MathWorks forum so I'm at a loss on how to proceed.
Thank you in advance!
I don't think it's possible to convert a library to a model, but you can programmatically add library blocks to models like so:
sys = 'testModel';
new_system(sys);
open_system(sys);
add_block('Simulink/Sources/Sine Wave', [sys, '/MySineWave']);
save_system(sys);
close_system(sys);
sim(sys);
You could even use the find_system command to list all the blocks in a library and then loop through them all and create a new model for each using the above code.
I am trying to run Omnet++ and matlab software in parallel and want them to communicate. When Omnet++ is running, I want to update the position of the node and for that I want to edit the .ned and .int files with matlab results continuously. During simulation I want to generate the result file using the updated files. I want just to update the position and don't want to add or delete any node. Please suggest me a way for proceeding?
matlab_loop
{
matlab_writes_position_in_ned_file;
delay(100ms);
}
omnet_loop
{
omnet_loads_ned_and_simulates;
//sca and vec should update;
delay(100ms);
}
Thank you.
NED and Ini files are read only during initialization of the model. You can't "read" them again after the simulation started. On the other hand, you are free to modify your parameters and create/delete modules using OMNeT++'s C++ API. What you want to achieve is basicaly: set your node position based on some calculations carried out by matlab code. The proper way to do it:
Generate C code from your matlab code.
Link that code to your OMNeT++ model
Create a new mobility model (assuming you are using INET) that is using the matlab code
What you are looking for seems to be more of a project rather than a question/problem which can be solved in Q&A site like stackoverflow.
Unfortunately, I have little understanding of matlab and V-REP to provide you a satisfactory answer. However, it seems that you will need to play around with APIs in lower levels.
As an example of coupling different simulation tools to form a simulation framework in case of need consider reading this paper and this
Also note the answer given by #Rudi. He seems to know what he is talking about.
Are there any easy ways (i.e. libraries) to create testing data for Caché, similar to the Populator and Faker gems for Ruby/Rails?
** edit **
I am trying to create test data for an Epic implementation. In addition to the electronic-medical-record (EMR) application, the implementation includes a tool called 'Text'. I'm hoping that I can use the data-generator with Text.
The %Populate class has a bunch of methods designed to help you create test data for your persistent classes.
Do ##class(MyApp.MyClass).Populate()
Could also use %PopulateUtils class directly to get random data returns directly.

mccrackend is right. The docs on this can be found here:
