I am using the SignalTap II logic analyzer on Quartus Prime Version : 18.1.1 Build 646 04/11/2019 SJ Standard Edition. I want to know if there is any significance of the background color in the waveform data display. I provide two BMPs. The file named stp1_UT_ADC_DATA.bmp has a white background. The file named stp1_10_27_11_59.bmp has a blue background.
