Address and Command Signals
Address (ddr_ad) and command signals (ddr_cas, ddr_ras, ddr_we) should meet set-up (t
timings at DDR interface with respect to positive edge of ddr_clk. Address and command signals are clocked
using negative edge of pll_mclk inside the FPGA as shown below. The ddr_clk signal is a delayed by pad
delay and board delay at DDR interface compared to pll_mclk inside the FPGA. As a result, 1/2clkx of set-up
and hold is provided by design.
