Example errors

Hello

I’m trying to implement the First example in ISE 10.1 with FrontPanel-FC7-3.0.11b. It synthesizes fine but when it tries to implement the Design I get the following errors:

ERROR:NgdBuild:604 - logical block ‘ep00’ with type ‘okWireIn’ could not be
ERROR:NgdBuild:604 - logical block ‘ep01’ with type ‘okWireIn’ could not be
ERROR:NgdBuild:604 - logical block ‘ep02’ with type ‘okWireIn’ could not be
ERROR:NgdBuild:604 - logical block ‘ep20’ with type ‘okWireOut’ could not be
ERROR:NgdBuild:604 - logical block ‘ep21’ with type ‘okWireOut’ could not be
ERROR:NgdBuild:604 - logical block ‘okHI/hicore’ with type ‘okHostInterfaceCore’
ERROR:NgdBuild:455 - logical net ‘ok2’ has multiple driver(s):

ERROR:NgdBuild:455 - logical net ‘ok2’ has multiple driver(s):

Any idea why this is happening.

I also commented out the
–library okFPsim;
–use okFPsim.all;

as I assume these are for the simulation.

Thanks Bren

As a side note I tried with counter and it works fine!

Bren-

Do you have the .ngc files available to the implementation tool in the proper directory?

I add all the ngc files the same way that I added them for the counter example that worked. Will try again this afternoon but any hints/help would be useful.
