When "ASY Symbol File" option has been selected in the CORE Generator project option, the following error occurs after generating the core:
"ERROR:sim:158 - Tcl error detected while configuring symbol pins.
ERROR:sim:159 - An internal error has occurred. Closing SPI-4.2 Lite GUI.
This error occurs because there is no Symbol file available for this core.
Deselect the ASY Symbol File option and try generating the core again.
If you are creating a schematic design, and need the symbol file, contact Xilinx Technical Support:
This issue has been fixed in SPI-4.2 Lite v4.1 Core available with ISE 8.2i IP Update #1. Please upgrade to the latest core.
