Project Navigator - X_ROC and T_ROC appear as undefined in Simulation Hierarchy

描述

If I attempt Post-PAR Timing Simulation, question marks appear to the left of specific Xilinx simulation primitives (e.g., X_ROC and X_TOC).

Example:

This problem is illustrated in the following screen shot. Observe that under Testbench -> UUT the boxes to the left of "NlwBlockROC - X_ROC" and "NlwBlockTOC - X_ROC" have question marks inside them.

The icon with a question markusually signifies that the tools are unableto locate a themodule or the library where the the module is located.However, simulation completes as expected.

Is this an issue I should be concerned about?

解决方案

In this case, the questionmark iconis misleading and should be ignored.

This icon is being used becauseProject Navigator does not have a user file to associate the module to, and therefore,uses the default undefined module icon.
