4.1i Virtex MAP - Error: "DesignRules:324 - Blockcheck: Dangling RAMCONFIG input..."


Keywords: Blockcheck, Dangling, RAMCONFIG

Urgency: Standard

General Description:
MAP fails with the following error:

"ERROR:DesignRules:324 - Blockcheck: Dangling RAMCONFIG input.
RAMCONFIG of comp Ubufgdll/Uclk/U4x/NET8262 is configured, but BYMUX is not used."


This problem can occur when the D input of an SRL16 is left undriven.

In the 5.1i software, the error message was improved so that it better explains the situation.
