General Board / Re: SVN

« on: January 14, 2022, 12:34:49 pm »

It's worth considering using a more robust database to hold the model and not using versioning. The svn process is cumbersome doesn't scale well (in my opinion). We've used Postgres backends for our last few projects and it's much easier (of course, you need to get the Postgres server set up). That's served our purpose well.

If you consider moving on past the svn approach, the more powerful relational databases work well in my experience.

Try opening the diagram's properties and then Elements/Collapse Embedded Elements.

General Board / List the flow properties that are in an interface block in a document?

« on: August 11, 2021, 10:34:23 am »

I know how to get attributes and methods to appear in a document. I'm using the standard document generator. Does anyone know how to get the flow properties held in an interface block to appear in a document? What boxes do I check?

Thanks

General Board / Re: How does one filter Ports and Objects out of a document?

Never mind. It's much simpler to use the "One of..." and opt types in rather than opt them out.

General Board / How does one filter Ports and Objects out of a document?

« on: August 09, 2021, 12:55:03 pm »

I generating a document and I don't want Port descriptions, Object descriptions, or Constraint descriptions to show up in it. I can filter out Ports with the element filter and settings shown below. If I add similar lines for Object and Constraint, then nothing, including Ports, gets filtered out. I've tried many combinations of Optional and Required. Anyone know how to prevent more than one type of element from showing up in a document?

Thanks

General Board / Re: Unwanted diagram padding in documents

« on: August 06, 2021, 10:14:28 am »

The side effect is that EA starts report memory allocation issues when it generates the document, I suppose because the bitmaps are large. I cut the resolution down to "High" from "Very High" and then it was OK, but I'm guessing the malloc issue will come back with longer documents.

It would be nice if Sparx would fix this obvious problem with the unwanted padding. I suppose I'll file a bug report, but I'm guessing they know about it already.

The problem seems to go away when I switch to a "bitmap" format rather than a "metafile" format. There may be side effects I haven't run across yet.

General Board / Unwanted diagram padding in documents

« on: August 04, 2021, 10:18:53 am »

I'm generating documents and getting a lot of white space around the diagram frame (see below - I clicked the diagram to show all the useless white space).  How do I get diagrams in documents to not have that extra space? I want the document to treat the diagram frame as the diagram's width.



Thanks

General Board / Re: EA slow when using networked repo

« on: July 13, 2021, 01:45:12 am »

EA interacts with the database a lot and any latency in the network (due to routers, firewalls, etc) will make it painfully slow. We typically use Postgres backends and run into the same slowness problem (it can be unusable). We get around that problem by setting up virtual machines at the same location as the database server and use remote desktop to run EA on them. We have no significant performance issues with that configuration.

There are some synchronization options under Start/Preferences/Source Code Engineering/C++

Those don't cover everything you ask about.

General Board / Re: SysML requirement id tagged value

« on: July 02, 2021, 01:32:37 am »

You could also export the requirements (include the guid so the imports will update the existing requirements, not add new ones), assign the tag value, and re-import them.

We've used auditing on requirements. It can be helpful to what changes have been made.

General Board / Protobuf Generation?

« on: June 11, 2021, 03:17:22 am »

I'm doing "due diligence." Does anyone know of a way to generate Google Protocol Buffers (protobufs) from a model? I've searched and haven't found anything. I know I could write a code-generation template to do it, but that would be an extensive project. I suspect there's a broad need for this capability and I'm surprised there's no solution.

Thanks

General Board / Interfaces and receptions - what sends the signal?

« on: June 03, 2021, 01:54:38 am »

I understand that, in SysML, a reception in an interface shows that the entity that supports the interface will accept asynchronous signals of the designated type (eg. IMU_Measurement in the image below). Is there a way to show that an interface will send those messages? (What's the opposite of a reception?). Do I have the wrong understanding?



Thanks

General Board / Re: Can't setup an EA database in Postgres - it's always worked before

« on: March 31, 2021, 06:58:10 am »

I figured it out. There's a bug in the EASchema_1558_PostgreSQL.sql script (and probably in the EASchema_1220_PostgreSQL.sql). I added the line noted below so the script wouldn't stop running if the "CREATE" line failed in the sql tool I use. Then the script ran through to completion and things worked out.

(There was a larger sequence of events, including updating the ODBC driver for Postgres, but the missing sql line could cause problems for others under the right circumstances).
