8.1.1.1. PHY or Core

Timing analysis of the PHY or core path includes the path from the last set of registers in the core to the first set of registers in the periphery (C2P), or the path from the last set of registers in the periphery to the first of registers in the core (P2C) and the ECC related path if it is enabled.

Core timing analysis excludes user logic timing to or from EMIF blocks. The EMIF IP provides a constrained clock (for example: ddr4_usr_clk) with which to clock customer logic; pll_afi_clk serves this purpose.

The PHY or core analyzes this path by calling the report_timing command in <variation_name>_report_timing.tcl and <variation_name>_report_timing_core.tcl.
