LogiCORE IP Video Timing Controller v6.0 - Why does the VTC lock signal remain asserted when the video clock is removed?

Description

Why does the VTC lock signal remain asserted when the video clock is removed?

Solution

When the video clock (clk) is lost then the VTC stops updating all of the registers.

To work around this users can use a clock mux to switch to another clock when the video clock (clk) is lost.
