7.1i PAR - "ERROR:Place:543 Due to placement constraints, the following 1 component"

描述

General Description:

My design fails during timing-driven mapping with the following error:

"ERROR:Place:543 - Due to placement constraints, the following 1 components

cannot be placed. The relative offsets of the components are shown in

brackets next to the component names.

FF mp4i_core_u0/mac_pkt_hdr_proc_u0/fr_cpu_out_port[1] (0, 0)"

I have tried to find the listed component name in my design so that I can analyze the failing constraints, but it does not exit.

解决方案

This failure is occurring in a placement algorithm that involves the "physical design." The names of the physical components are derived from output net names, not from the associated instance names in the "logical design." This logic can be identified by searching for the net name and identifying the logic that drives it.
