6.1i System Generator for DSP - What are parameter variable names and definitions for each Xilinx block that controls the S-Function?

Description

General Description: 

How do I find information on the variable names and functions that drive the S-Function simulating a given Xilinx block? These variables are often referred to by the following names: 

 

Model Parameters 

Common Block Parameters 

Block Specific Parameters 

Mask Parameters 

 

Simulink block parameters are described in the Help information at: 

 

Help -> Content -> Simulink -> Using Simulink -> Model and Block Parameters -> Mask Parameters 

 

Does the help information in System Generator for DSP offer similar parameters?

Solution

Currently, no detailed help on this topic is available; however, you can find this information in the following two ways: 

 

1. Block Data Tips 

 

Block data tips offer insight into the variables underneath the masked Xilinx blocks. You can activate these tips by selecting the following menus in a Simulink model: 

 

View -> Block data tips options -> Parameter names and values 

 

If you rest the mouse pointer on any block, the parameter names will appear.  

 

2. Unmask a Subsystem 

 

Each Xilinx block is a masked subsystem that hides the details of the simulation function for that block and presents the block parameters to you in a readable, user-friendly manner. These block parameters control the parameter variables that drive the S-Function simulation model.  

 

To unmask a block and view its details, you must first unlink the block from its library as follows: 

 

Right-click on the block -> Link options -> Break Link 

 

This enables editing of the block so that it can be unmasked: 

 

Right-click on the block -> Edit Mask 

 

This reveals the Mask Editor -- you can view all parameter variables under the Parameters tab.
