13.x ChipScope Pro - How do I include an ICON in a design which contains an MDM debug module?


When I add ChipScope cores to a design that has an EDK project as a module (including an MDM debug module), MAP errors similar to the following occur:

"ERROR:PhysDesignRules:1683 - Unsupported programming for BSCAN block and JTAG_CHAIN attribute value 2. The BSCAN
component debug_module/debug_module/Use_E2.BSCANE2_I has placement which requires the JTAG_CHAIN attribute to be set
to the value 1. The JTAG_CHAIN attribute must be changed or the programming for the BSCAN block must be moved to a
location corresponding to the JTAG_CHAIN attribute setting"

How do I include an ICON in a design which contains an MDM debug module?


You need to ensure that a different USER instruction and hence, BSCAN primitive, is selected for the ICON than the MDM. The MDM defaults to USER1, so in the CORE Generator toolor the ChipScope Inserter, you should use USER2/3/4. This prevents a conflict on the BSCAN primitives. The USER instruction is selectable in the CORE Generator tool and ChipScope Inserter flows. By using the PlanAhead tool, this issue should be automatically resolved.
