Lvds_io

Hi, I am working on a project and a part from it is using LVDS_IO with the buffer as a comparator to compare 2-input signals. My question is how we send the analog signal to the FPGA even though i...

LVDS input buffers aren't designed as analog comparators and have limited common mode range, please refer to the datasheet section of the device manual for details.

They nevertheless may work as comparators, there's nothing to do but assigning an LVDs IO-standard to the input.

It's not clear what you want to simulate and with which tool?
