5.1isp1 NGDAnno - "ERROR:Anno:252 - Error occurred during close of BRAM update process. Tantiation of 'xxx' failed. The design unit was not found."

描述

Keywords: NGDAnno, error, 252, DATA2BRAM, BRAM, update, process, Tantiation, found, info, NCD, 564, block RAM, blockRAM, BMM

Urgency: Standard

General Description:
When I use NGDAnno to perform a post-MAP simulation, the following info and error messages occur if I have specified a .mem or .elf file:

"INFO:Ncd:564 - BlockRam comp(s) not placed. The BlockRam specified in the BMM File is not LOC'ed. No update of placement information has occurred for the BMM File."

"ERROR:Anno:252 - Error occurred during close of BRAM update process. Tantiation of 'counter_module' failed. The design unit was not found."

解决方案

This error occurs because the software is trying to receive BRAM placement information from the NCD file. As this is a mapped NCD file, no placement information exists, and the software reports the above error.

This problem is fixed in the latest 5.1i Service Pack, available at:

The first service pack containing the fix is 5.1i Service Pack 2.
