iam using spartan3 with xc3s200 stater kit.
i connected my user ip to the microblaze the sysnthesis is going well but when iam implementing the design the following error is dispalyed:
"NgdBuild:604 - logical block ‘U0’ with type ‘come’ could not be resolved.
A pin name misspelling can cause this, a missing edif or ngc file, or the
misspelling of a type name. Symbol ‘come’ is not supported in target
‘spartan3’. "
‘come’ is my vhdl file added as an ip to the microblaze. i used OPB to connect my ip.

plz any one’s help would be appreciated…



Are you using an Opal Kelly XEM, or the Xilinx supplied XC3S200 Stater Kit? If you’re using the Xilinx product, they should be able to help you out.

Opal Kelly will have a beta release of a MicroBlaze peripheral in the near future that connects as an OPB peripheral and gives communications to and from the PC via the standard Opal Kelly Wire, Trigger, and Pipe HDL modules, along with the okHostInterface module.
