The general-purpose clock,
clk50
, is used for switch debounce and by the init-run-park
state machine and is a 50 MHz free-running clock.
A free-running 100 MHz clock, clk100
, is used by the test pattern
generator.
Both clocks are generated by a single PLL (AMD - Xilinx IP), and are phase-aligned.
The reference clock for the PLL is sysclk_p/n
.
