7.1i EDK - Virtex-4 Chipscope_icon_v1_01_a: Why are my ChipScope cores being removed when C_SYSTEM_CONTAINS_MDM is set to 1?

Description

Keywords: icon, OPB_MDM

When I target a Virtex-4 device, the ChipScope cores are being removed when C_SYSTEM_CONTAINS_MDM is set to 1.

Why is this occurring?

Solution

The paramter C_SYSTEM_CONTAINS_MDM should be set to 0 (even when including a opb_mdm core) for Virtex-4, since there are four independent BSCAN_VIRTEX4 primitives and they do not need to be shared between chipscope_icon and opb_mdm.
