10.1 ChipScope Coregen - ERROR:PhysDesignRules:10 / WARNING:PhysDesignRules:10 - The network > is completely unrouted.

Description

When I have ChipScope Cores in my design, I see the Design Rule Errors with the CONTROL bus in FPGA Editor or Bitgen.

FPGA Editor

WARNING:PhysDesignRules:10 - The network <CONTROL<2>> is completely unrouted.

Bitgen

ERROR:PhysDesignRules:10 - The network <CONTROL<2>> is completely unrouted.

How do I work around this issue?

解决方案

This is related to how XST handles the Bidirectional CONTROL bus. To work around this issue, use the following Implementation options:

XST

-keep_hierarchy No

-read_cores No

NGDBUILD

Remove the -insert_keep_hierarchy option.
