Description

Reports TCCS for dedicated LVDS transmitters.

In designs that implement the LVDS I/O standard, transmitter channel-to-channel skew (TCCS) is the
timing difference between the fastest and slowest output transitions, including tco variations and clock
skew.

Example

project_open top
create_timing_netlist
