What Is Simulation? 4

Posted by Guy Rouleau,

What Is Simulation?  This week we are taking a break from Simulink features and capabilities to take a step back and look at the history of simulations. What Is Simulation? Sometimes it is good to take a step back and remember why we do simulations in the first place. What is simulation? What kind... read more >>

Frames… from signals to blocks 5

Posted by Guy Rouleau,

Frames… from signals to blocks Today I want to talk about an important topic for DSP System Toolbox and Communication System Toolbox users: Frame-Based Processing Beginning in R2010b, MathWorks started to significantly change the handling of frame- and sample-based processing. Currently, we are in a transition phase and it's time to update your models to the... read more >>

How Many Blocks are in that Model? 12

Posted by Seth Popinchalk,

How Many Blocks are in that Model? My colleague Sam and I wanted to find an example model with about 10,000 blocks.  I suggested the HL-20 model from the Aerospace Blockset, asbhl20.mdl.  Sam decided to measure the total number of blocks by running sldiagnostics: >> [t,s] = sldiagnostics('asbhl20','CountBlocks'); s(1) ans =     isMask: 0       type: 'asbhl20 Total blocks'      count: 5700 Sam quickly sent me... read more >>

Better Bus Modeling (How to remove Bus/Mux confusion) 5

Posted by Seth Popinchalk,

Better Bus Modeling (How to remove Bus/Mux confusion) Earlier this week, Guy and I were discussing the sometimes-strange behavior of mux and bus signals.  Sometimes people find a Mux block in their model that appears to output a bus signal.  In this post, I will explain the underlying cause of this behavior and give you a short Simulink history lesson. Don’t let your... read more >>

The Answer for Large Scale Modeling: Model Reference 20

Posted by Seth Popinchalk,

The Answer for Large Scale Modeling: Model Reference Your model is someone else’s component.  The Model block allows you to treat a Simulink model as a component within a larger system.  In this post I will discuss the basic concepts of model reference and look at what is new for R2008b. What is Model Reference? Model reference is the Model block from the... read more >>

R2008b Simulink: Sample Time Colors 6

Posted by Seth Popinchalk,

R2008b Simulink: Sample Time Colors Simulink models present a schematic layout of your algorithm.  The diagram encodes information about the system in the form of block icons, data type annotations, and sample time colors.  In technical support, I have seen many questions like, How can I print on a black and white printer and show... read more >>

A Historical Tour of the Library Browser 19

Posted by Seth Popinchalk,

A Historical Tour of the Library Browser When I started using Simulink, the libraries were organized a little differently than they are today. There were fewer blocks and no such thing as a Library Browser. Take a look at Simulink 1.3c from 1996. This version was a little before my time. However, users of that... read more >>
