I am using the Piecewise Lienar Source to generate a random voltage waveform stored in 2 separate .csv files. I have 4000 data points per .csv file and am combining the two .csv files to generate the single voltage source. Individually each .csv file reproduces the waveform accurately but when I combine the 2 .csv files, I see that the second half of the waveform seems to use lesser samples(data points) than available leading to a waveform that looks "digitized" with insufficient samples. Why does this happen wherein the data points entered in the PWL list seem to be dropped randomly leading to an inaccurate source? Is this an issue with the PWL source(max no. of data points it can handle) or with the waveform viewer?
