Creating multiple time entities from a single SimEvents entity generator
显示 更早的评论
I am trying to build a CAN bus simulation with multiple messages. The message list may change in size depending on the program. I can initialize the message list and sizes in the workspace prior to running the simulation.
What I'd like to do is have one Time-Based Entity Generator generate more than one CAN message (i.e., entity). The intergeneration times for each entity will be different. I'm trying to input a vector of times, and every time I do, I get an error saying the time must be a scalar.
Is it possible to do what I'm thinking? Thanks!

In the Time-Based Entity Generator block, set the "Generate entities upon" parameter to be "Intergeneration time from port t". Now you can use an Event-Based Sequence block to feed in a vector of intergeneration times. If you want multiple simultaneous entities at a given time, then use 0 as the intergeneration time, e.g. [1 1 0 0 0 1] will generate entity at T = 0,1,1,1,1,2.

I do not see why not. If you feed the entities into the SET ATTRIBUTE block, you should be able to set values for simultaneous entities simultaneously. This is where the beauty of event-based SimEvents comes out.

You can also try to use this: -Set Attribute for one entity. -Split the entity using the "Entity Splitter" block under Entity Management library; this should give you multiple entities with the same Attribute values.
