AR# 42827: MIG v3.8 Virtex-6 QDRII+ - ChipScope cores are not detected in the JTAG device chain
MIG v3.8 Virtex-6 QDRII+ - ChipScope cores are not detected in the JTAG device chain
ChipScope Analyzer cores are not detected when the BIT file is downloaded on board for MIG v3.8 Virtex-6 QDRII+ SRAM designs due to an issue with BITGEN options. The default option for the QDRII+ designs is "-g next_config_addr:0x00000000". This causes the ChipScope Analyzer to not find the core units after configuration:
"INFO: Found 0 Core Units in the JTAG device Chain."
To work around the problem the BITGEN option "next_config_addr" can be removed or set to "-g next_config_addr:None" in the "bitgen_options.ut" file located in the "par" folder.
This is scheduled to be fixed in the 13.3 release.
