LogiCORE 3GPP LTE Turbo Encoder v3.0 - Release Notes/README for 3GPP LTE Turbo Encoder v3.0 rev 1 Patch


This Answer Record contains the Release Notes for the CORE Generator 3GPP LTE Turbo Encoder v3.0 rev 1 Patch which deals with the inability to target the core at Virtex-6 or Spartan-6.


During synthesis, XST now checks that the generated core meets the IEEE VHDL Standard and is LRM (Language Reference Manual) compliant. As a result of these checks since ISE 11.3 the core will not generate for Virtex-6 or Spartan-6 families

In order to target Virtex-6 and Spartan-6, you need to install the patch described below:

1. Before you install this patch, ensure that you have the following installed on your machine.

NOTE: If you need any of the service packs, libraries, or IP Updates, you can obtain them from the Download Center at:


- ISE 11.3i

2. Download the 3GPP LTE Turbo Encoder v3.0 patch from:


3. Extract the ar33617_3gpp_lte_turbo_encoder_v3_0_rev1.zip to a temporary directory so as to read the AR33617_3GPP_LTE_Turbo_Encoder_V3_0_REV1_readme.txt file for more information on whether to extract the zip file to %XILINX% installation directory or use MYXILINX environmental variable.

Patch Fixes

Issue: The core cannot be generated for either Virtex-6 or Spartan-6 using ISE 11.3.

Symptom: When generating the core, the error message "ERROR:coreutil - XST has returned an error: ERROR:HDLCompiler:432"? appears and the core is not created.

Please see (Xilinx Answer 30631 ) for a detailed list of LogiCORE 3GPP LTE Turbo Encoder Release Notes and Known Issues.
