8.1i Spartan-IIE PAR - An incorrect DRC check of DLL connectivity causes an invalid error (ERROR:Place:110)

Description

The DLL configuration of a Spartan-IIE triggers an incorrect placer error; the error refers to secondary DLLs that do not exist in Spartan-IIE devices. The following error occurs: 

 

"ERROR:Place:110 - The DLL iCLKDLL_A (Secondary DLL) is one of a pair of DLLs. The other DLL (Primary DLL) is iCLKDLL_2X. Because they are a pair, they must be placed together. The Secondary DLL is NOT placed in a secondary DLL location."

Solution

This issue is currently under investigation. Meanwhile, you can work around this problem by setting the following environment variable: 

 

PCs: 

set SKIP_PLACE_DLLDRC=1 

 

Workstations: 

setenv SKIP_PLACE_DLLDRC 1
