Hi @farhathsuj,

Right click on the signal name, then select "Properties", next select "Format" tab, then click on the "Analog" type option and then change the scale as required in the analog display window.

Three possibilities to look at.  You may be displaying a signed number as unsigned, you may be displaying an insigned number as signed, or one of yur busses needs an extra bit and your signal is overflowing, thus wrapping around.
