Some designs choose to swap the positive and negative side of the of the JESD204 lanes. One reason for this would be because it can simplify the PCB layout. To support this add a parameter to the jesd204_soft_pcs_tx module that allows to specify whether the lane polarity is inverted or not. The way the polarity inversion is implemented is for free since it just inverts the output mapping of the 8b10b encoder LUT tables. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> |
