To work around this issue, use a value of 1 for the dbg_hub core and use 2, 3, or 4 for any other IP that uses the BSCAN primitive element (such as the ChipScope Pro ICON core).
To change the
Debug Core Options on the dbg_hub core, post-synthesis:
- Select the dbg_hub instance (under the Instance Properties window).
- Select Debug Core Options, and set the C_USER_SCAN_CHAIN attribute value.
To change the
Debug Core Option on the ChipScope Pro ICON core, configure the core using the CORE Generator tool.
