Hello,
I am trying to use some custom IP (an Interrupt controller) with my SOC (Coldfire CFv1) and I tried using a custom IP from the devices.vhd for my controller but when I did, the free GRMON doesn’t allow me to open it. Is this a feature or handicap of using the free GRMON 
The evaluation version only allows GRLIB GPL cores and vendor VENDOR_CONTRIB cores.
Try changing your vendor ID to VENDOR_CONTRIB.
So, if I make VENDOR_CONTRIB and CONTRIB_CORE1, 2 or 3 for the IP name?
Hi Salman,
Yes, your IP need to output VENDOR_CONTRIB in the “vendor” part of the PnP vector and CONTRIB_CORE#, where # is 1, 2 or 3, in the “device” part of the vector.
Best regards,
Martin
I think that is giving some issues with GRMON. But I will double check I spelled everything correctly.
