There is little we can help with with only the error message. 

Try increasing the P&R effort.

what about the previous warnings on signals with no driver? Are these your signals or from the wrapped core?

How does the simulation look ?
You have a bunch of logic with no drivers reported.
thats not good start

Whats its telling you is you either have code that has no input or output some where, and as such is being optimised away by the placer.
Or you have tried to do something that this chip cant do, like connect an internal clock net to an output , or drive a pin that can not be driven

Always simulate first. That gets rid of the first group of problems, and leaves you with the simpler second group.

that are signals with no driver

[harinatha.reddy@eldaas.com]

ya i simulated. there is no problem in simulation

[drjohnsmith]

Its time to share your project with us so we can help further,

[drjohnsmith]

what are you doing with unisim.vcomponents.all

You decalre it at the top inside pragma synthesis of f/ on,

then re definfe it again so synthesis can see it !

ok please find the attached project file file. i have on doubt in chipscope inserter, i am anable to get all topmodule ports can anyone help me how to get all ports in chipscope.if any reference designs for pci32 are there please provide me 

[drjohnsmith]

looks like the complete PCI core is empty !

could it be that you have no purchased licence for the core ?

@drjohnsmith 

LoL

[harinatha.reddy@eldaas.com]

i haved purchased license. but i am newly using chipscope. so please provide me any references how to use chipscope analyser

[drjohnsmith]

No chipscope in the files you shared,

so that can't be your problem...

Is this a new problem ?

If so please lcose this forum, and open a new one.

[harinatha.reddy@eldaas.com]

chipscope is there sir in that files. it is Top_CDC.cdc file. in topmodule project it is there

[rofl]
