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:
Common Block Parameters
Block Specific 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?
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.
