Clock Domains and Clock Generation for the Application LayerThe following illustrates the clock domains when using coreclkout_hip to drive the Application Layer and the pld_clk of the IP core. The Intel-provided example design connects coreclkout_hip to the pld_clk. However, this connection is not mandatory. Inside the Hard IP for PCI Express* , the blocks shown in white are in the pclk domain, while the blocks shown in yellow are in the coreclkout_hip domain.
As this figure indicates, the IP core includes the following clock domains: pclk, coreclkout_hip and pld_clk.
