How can I use the embedded parameters taken by the S-function block as input to the block?

• I have a S-function block that has some _ input ports_ in simulink.
• It also has some _ input parameters_ that need to be specified in block properties.
• I want to use those _ input parameters_ at the _ input port_ such that I can use variable values of those parameters during simulation.
• One way to do it is to use the workspace. But I want to use the online generated parameters rather than those saved in the workspace.
