XST - "ERROR:Xst:624 - Could not find instance <inst_my_sub> of cell <my_sub> in <top>"

描述

Keywords: 5.1i, 4.1i, incremental synthesis

Urgency: Standard

General Description:
When I use incremental synthesis in XST, the following error occurs:

"ERROR:Xst:624 - Could not find instance <inst_my_sub> of cell <my_sub> in <top>"

解决方案

This error occurs either because your design was run in non-incremental synthesis mode and was then changed to run in incremental mode, or because the decomposition of your design changed.

To avoid this error, delete all versions of the NGC file that were previously generated by XST.

If the above suggestion still doesn't solve the problem please open a webcase with Xilinx Technical support at http://www.xilinx.com/support/clearexpress/websupport.htm
