[partial-reconfig] Question on DPR tutorial by Gregory Mermoud

["Ye Zijia" <yezijia@xxxxxxxxxx>]

Hi, 

     thanks for your reply Peter. Another question i have is if i am using Virtex II Pro instead of Spartan 2. What should i change or modify from the original design files ? I tried using the bus macro file ,bm_4b_v2p.nmc and changing the bm8.vhd files bus1 and bus2 to bm_4b_v2p.nmc from bm_4b_s2.nmc but this is the error i get using ngdbuild.

ERROR:NgdBuild:76 - File "C:\DPR\implementation\top_level_initial/bm_4b_v2p.nmc"

   cannot be merged into block "busIncToReg_bus2" (TYPE="bm_4b_v2p") because one

   or more pins on the block, including pin "LI<3>", were not found in the file.

    Please make sure that all pins on the instantiated component match pins in
   the lower-level design block (irrespective of case).  If there are bussed
   pins on this block, make sure that the upper-level and lower-level netlists
   use the same bus-naming convention.

Can anyone tell me whats went wrong and what i should do to rectify it ? Please advise. 

Thanks for your time !

Regards,

Zijia
