ERROR: [PlanAhead 12-727] Error: Multiple ChipScope ICON cores detected during netlist scan

Hi,

I want to instance two ILA in different source file.

When I only copy two "ICON + ILA" in code, there is an error. As topic shows.

Does it mean, for one project, only one ICON can be instanced?

How to instance multipy ILA in project?

 

Thanks.

Jie

you can have multiple ILA / VIO cores but only 1 ICON is needed to communicated over JTAG. Does 1 ICON work for you?

Hi Jheslip,

Thanks for your reply.

Do you mean in my codes, only one module instance ICON, while ILAs are instanced in different other modules?

Then my concern is how to define the CONTROL[35:0] in the moudle that only include ILA.

I will try later...

Dear sunje,

 

I would recommend not instantiating the ILA cores manually in your design and instead use Planaheads Debug feature to add the ILA cores. Planahead takes care of generating and connecting the ICON automatically.

 

Best regards,

Martin
