XST - "ERROR:HDLParsers:1209 - .vhd Line xx. : Undefined symbol (last report in this block)"

描述

General Description:

When I synthesize a VHDL design with XST, the VHDL parser issues the following error:

"ERROR:HDLParsers:1209 - <file>.vhd Line xx. <inst>: Undefined symbol (last report in this block)"

Why is this error message occurring?

解决方案

This message is followed by similar messages: "HDLParsers:3312" and "HDLParsers:3313". The messages indicate that multiple instances of the unknown component have been found, and rather than reporting the same message many times, the errors are stopped to save report file space.
