Description

The XPS_LL_TEMAC, while using the soft TEMAC option, inserts the IODELAY components on the GMII interface inherently.

Solution

This tactical patch allows you to directly hook up the PCS/PMA core to the GMII interface of XPS_LL_TEMAC by setting the parameter, C_INCLUDE_IO= 0.

1. Download the archive: http://www.xilinx.com/txpatches/pub/applications/misc/ar33840.zip.
2. Extract the archive to the pcores folder in the project.
3. Rescan the user repositories in XPS.
4. Disable the IODELAY components by selecting C_INCLUDE_IO = 0 during configuration of the IP.
5. Reimplement the design.

NOTES:

• This patch is for use in version 11.4 or later of EDK containing v2.03.a of the XPS_LL_TEMAC core.
• The PCS/PMA core is not included with XPS_LL_TEMAC or any IP delivered through EDK and should be added externally.
