xilinx microblaze and picoblaze on a spartan 3e starter kit

Dear all,

I'm trying to make an IP for microblaze using code including a Picoblaze processor. So that's a pico/micro blaze mix on a spartan 3e and it seems to be incompatible because of BSCANS: Number of BSCANs: 2 out of 1 200% (OVERMAPPED)

Does anyone has a clue on how to solve that?

thanks in advance, Laurent

Hi,

Seems like you try to use to BSCAN in your FPGA. IP that uses BSCAN are ChipScope and MDM, these can share one BSCAN but needs to be configured for it. What is using the two BSCAN primitives in your design?

Hi,

The only way to share a BSCAN is that the designs are created for sharing. The MDM is designed for sharing since it can be used together with ChipScope which also uses BSCAN. But I don't think the picoblaze usage are made for sharing the BSCAN and thus you would need to modify the code to allow sharing.
