To proof reliability of the complicated CCD imaging system and to debug it easily
self-check figures are indispensable as image data simulation source. These figures should have the characteristic of push-scan similar to linear CCD
and have variety in gray in column and row direction. As one of numerous figures
this paper elaborates on the distinguishing figure's design procedure
implement and significance. This design was implemented with VHDL language programming based FPGA. The author applied TEXTIO function to export figure data to a text through gate-level simulation with Modesim
then imported the text and showed the expected figure in MATLAB. These figures have been applied and proved out in a CCD imaging system.
