Pathological SDI test pattern

The SDI pathological test pattern is specifically designed to stress test the SDI equalizer and PLL performance.
The test pattern consists of a static test image with the top half of the lines filled with a shade of magenta, and the bottom half of the lines filled with a shade of gray.
The option to add a border around the SDI pathological pattern is not enabled because this would reduce the effectiveness of this test for SDI interfaces.
The table lists the values used for each bar in both RGB and YCbCr color spaces for 8 bits per color sample. If the requested output is not in 8 bits per color sample, the IP core truncates or increases these values accordingly.
| Main AC | |||
|---|---|---|---|
| Color | RGB | RGB 0x00 | YCbCr |
| Magenta (Upper bar) | (195, 35, 215) | (C3, 23, D7) | (102, 192, 192) |
| Gray (Lower bar) | (68, 68, 68) | (44, 44, 44) | (68, 128, 128) |
