Hi Shubham,

I understand that you are trying to import test vectors from an Excel sheet to a Simulink model without using signal generator block.

Here are the alternative methods you can try:

Using "From Spreadsheet" block:

Before importing, make sure the test data in the Excel sheet is in the correct format supported by "From Spreadsheet" block (refer to documentation)
Import test vectors from Excel to "From Spreadsheet" variable and run your desired test by using this block as signal generator.

Using "From Workspace" block:

Import the test vectors from Excel to a MATLAB workspace variable and convert the test data into the supported data type for loading ( refer to documentation below )
Use the "From Workspace" block to read this test data variable into the Simulink model and run your desired test

Links to relevant documentation and examples:

From Spreadsheet block: https://in.mathworks.com/help/simulink/slref/fromspreadsheet.html

From Workspace block: https://in.mathworks.com/help/simulink/slref/fromworkspace.html?searchHighlight=from%20workspace&s_tid=srchtitle_support_results_1_from%20workspace

Load data using the "From Workspace" block: https://in.mathworks.com/help/simulink/ug/load-data-using-the-from-workspace-block.html

Hope this helps!
